Saint Tammany County

Saint Tammany Parish (often referred to as a county equivalent) is located in southeastern Louisiana on the north shore of Lake Pontchartrain, across from New Orleans and bordering Mississippi to the east. Formed in 1810 during Louisiana’s early territorial period, it developed historically around lake and river transport and later expanded as part of the Greater New Orleans metropolitan region. The parish is mid-sized and among the more populous jurisdictions in the state, with roughly 270,000 residents. Its landscape includes piney woods, wetlands, and waterways such as the Tchefuncte River and Lake Pontchartrain, supporting outdoor recreation and a mix of suburban and semi-rural communities. The economy is anchored by local services, retail, health care, construction, and commuting ties to regional employment centers. Cultural life reflects a blend of Gulf Coast and North Shore influences. The parish seat is Covington.

Saint Tammany Parish (often referenced as Saint Tammany County in national datasets) is located in southeastern Louisiana on the north shore of Lake Pontchartrain, directly across from the New Orleans metropolitan area. It is part of the state’s Greater New Orleans region and serves as a major residential and employment center in the Northshore subregion.

Population Size

According to the U.S. Census Bureau QuickFacts for St. Tammany Parish, Louisiana, Saint Tammany Parish had an estimated population of approximately 269,000 (2023 estimate). The same Census Bureau profile lists a 2020 decennial census population of about 264,000.

Age & Gender

Age and sex structure for Saint Tammany Parish is reported in the Census Bureau’s county profile tables (QuickFacts):

• The U.S. Census Bureau QuickFacts for St. Tammany Parish provides the share of residents under age 18, age 65+, and related age indicators.
• The same Census Bureau profile provides the female share of the population, which can be used to describe the county’s gender ratio in percentage terms (female vs. male).

Racial & Ethnic Composition

Racial and Hispanic/Latino origin composition is reported in the Census Bureau’s county profile:

• The U.S. Census Bureau QuickFacts for St. Tammany Parish lists percentages for major categories such as White, Black or African American, Asian, two or more races, and Hispanic or Latino (of any race), along with additional categories where available.

Household and Housing Data

Household structure and housing characteristics are available in the Census Bureau’s county profile tables:

• The U.S. Census Bureau QuickFacts for St. Tammany Parish includes key measures such as number of households, average household size, owner-occupied housing rate, median value of owner-occupied housing units, and median gross rent (where reported in the selected profile year).

Saint Tammany Parish spans suburban and semi-rural communities north of Lake Pontchartrain; denser areas near the I‑12 corridor generally support stronger fixed-network options than lower-density areas, shaping how residents access email and other online services.

Direct county-level email usage statistics are not routinely published; broadband and device access are used as proxies for likely email adoption, based on standard internet access requirements. According to the U.S. Census Bureau (data.census.gov), key digital access indicators for Saint Tammany include household broadband subscription and computer ownership, which track the share of homes positioned to use webmail or app-based email reliably. Age composition also influences adoption: Census age tables for the parish show a large working-age population alongside substantial older cohorts, and older age groups tend to have lower internet adoption rates than younger and middle-aged adults, affecting email uptake patterns. Gender distribution is available in the same Census profiles, but it is generally a weaker predictor of email use than age and connectivity.

Connectivity constraints reflect typical parish-wide patterns: service availability and speeds can vary by neighborhood and distance from infrastructure; federal broadband availability maps (see FCC National Broadband Map) document provider coverage and technology limits.

Saint Tammany County (often referenced locally as St. Tammany Parish) lies on Louisiana’s north shore of Lake Pontchartrain, directly across from New Orleans. The parish includes fast-growing suburbs and exurbs (e.g., Mandeville, Covington, Slidell) as well as lower-density, forested and wetland-adjacent areas near river systems and the lake. This mix of higher-density corridors along I‑10/I‑12 and lower-density residential/rural tracts affects mobile connectivity: coverage and capacity tend to be strongest near major roadways and population centers, while performance variability is more common in heavily vegetated areas, near water, and in lower-density tracts where fewer cell sites serve larger areas.

Key distinction: network availability vs. adoption

Network availability describes whether mobile broadband service is reported as offered in an area (coverage). Adoption describes whether residents actually subscribe to and use mobile service (household access, device ownership, and internet subscriptions). Availability can be high while adoption varies due to cost, preferences (fixed broadband), device access, and demographic factors.

Mobile penetration / access indicators (adoption)

County-specific “mobile penetration” is not typically published as a single metric. The most commonly used, publicly available adoption indicators at local geographies come from the U.S. Census Bureau’s American Community Survey (ACS), which measures household internet subscriptions and computer/device availability, including cellular data plans.

• Household internet subscription indicators (ACS): The ACS includes estimates for households with:

  • a cellular data plan (with or without another subscription),
  • broadband such as cable/fiber/DSL,
  • satellite, and
  • no internet subscription.
    These tables support analysis of mobile-only reliance (households with a cellular data plan but no fixed subscription) versus households using mobile as a complement to fixed service. Data are available at county/parish level and for smaller geographies where sampling permits. Source: Census.gov data portal (ACS “Internet Subscriptions in Household” tables).

• Device access indicators (ACS): The ACS also reports whether households have computing devices such as smartphones, tablets, or computers, which can be used to approximate the prevalence of smartphone access relative to other device types (not a direct measure of active service). Source: Census.gov (ACS computer and internet use tables).

Limitations (county level):

• ACS provides estimates (survey-based) and margins of error; device categories are household-level and do not directly measure individual subscriptions or carrier market share.
• Carrier “subscriber counts” are generally proprietary and not published for Saint Tammany as a standalone public statistic.

Mobile internet usage patterns and network availability (4G/5G)

Availability in Saint Tammany is best described using coverage reporting and broadband availability datasets. The principal federal source is the FCC’s Broadband Data Collection (BDC).

• 4G LTE and 5G availability: FCC BDC includes provider-reported coverage for mobile broadband, including technology categories that can be used to map where 4G LTE and 5G are reported available. Coverage is generally strongest in and around the parish’s incorporated and higher-density areas and along major transportation corridors, with more variable footprints in lower-density or environmentally complex areas. Source: FCC National Broadband Map.

• Service quality vs. availability: The FCC map is a coverage/availability dataset and does not directly represent real-world throughput at every location, indoor coverage, congestion effects, or performance during peak demand. It is possible for an area to be listed as covered yet experience weaker indoor signal or lower speeds due to terrain, building materials, and cell loading.

• State broadband context: Louisiana’s broadband initiatives and mapping work provide additional context on regional connectivity constraints and funding priorities that can indirectly relate to mobile vs. fixed reliance. Source: ConnectLA (Louisiana Office of Broadband Development and Connectivity).

Usage patterns (adoption-side proxies):

• The most defensible county-level proxy for mobile internet reliance is the ACS measure of households with a cellular data plan, including mobile-only households (cellular data plan without a fixed subscription). These statistics describe adoption and reliance patterns rather than network capability. Source: Census.gov (ACS internet subscription data).

Limitations (county level):

• County-level public datasets generally do not publish Saint Tammany-specific breakdowns such as “percentage of mobile traffic on 5G vs LTE,” average data consumption per user, or handset-based radio attachment rates; these are typically held by carriers or third-party analytics firms.

Common device types (smartphones vs. other devices)

Publicly available, county-level device-type data are limited. The ACS provides household device availability categories that are widely used for local reference.

• Smartphone availability: ACS includes estimates for households with a smartphone, which serves as the primary county-level indicator of smartphone access.
• Other connected devices: ACS also tracks items such as tablets and traditional computers, enabling a high-level comparison between smartphone presence and other device access at the household level. Source: Census.gov (ACS computer/device availability).

Limitations:

• ACS device availability does not indicate whether devices are used on cellular networks versus Wi‑Fi, nor does it capture device models, operating systems, or 5G-capable handset share.

Demographic and geographic factors influencing mobile usage and connectivity

Geography and built environment (availability and performance):

• Population distribution: Higher-density areas and commercial corridors support more cell infrastructure and higher capacity, which typically improves availability and reduces congestion risk compared with sparsely populated tracts.
• Vegetation and water: Forested areas and proximity to water bodies (Lake Pontchartrain and river systems) can affect propagation characteristics, contributing to coverage variability and indoor signal attenuation in some locations.
• Transportation corridors: Major routes (I‑10, I‑12 and principal arterials) tend to correlate with stronger and more continuous coverage footprints due to demand and infrastructure placement.

Socioeconomic and housing factors (adoption):

• Income and affordability: Household adoption of cellular data plans and fixed broadband is strongly associated with income and affordability constraints. Mobile-only reliance is commonly higher where fixed broadband is less affordable or less available. County-level adoption patterns are best supported using ACS internet subscription tables. Source: Census.gov (ACS).
• Age structure: Older populations generally show lower rates of smartphone-centric adoption and may maintain voice-centric usage or rely on household-shared connectivity patterns; ACS age cross-tabs for device/internet measures are limited, and detailed breakdowns may require careful use of available tables and margins of error.
• Urban/suburban vs. rural residential patterns: Lower-density housing patterns can raise per-household infrastructure costs for both fixed and mobile networks; for mobile, fewer sites covering larger areas can reduce capacity and indoor reliability compared with denser neighborhoods.

Practical interpretation for Saint Tammany County (data-grounded summary)

• Availability: 4G LTE and 5G availability should be treated as coverage claims best verified through the FCC National Broadband Map, with strongest continuity expected in population centers and along major corridors and more variability in lower-density/forested areas.
• Adoption: The most authoritative public indicators of mobile access and reliance are ACS measures of household cellular data plan subscriptions and household smartphone availability, accessible via Census.gov.
• Device mix: Public county-level data can describe smartphone presence in households versus other device categories, but not detailed handset capabilities (such as the share of 5G-capable phones).
• Limitations: Carrier subscriber counts, network performance metrics, and usage volumes specific to Saint Tammany are not generally available in public county-level datasets; published sources primarily support analysis of reported coverage (FCC) and household adoption (ACS).

Saint Tammany Parish (county-equivalent) sits on the north shore of Lake Pontchartrain in southeast Louisiana and is part of the Greater New Orleans region, with major population centers including Covington, Mandeville, Slidell, and Madisonville. Its commuter ties to New Orleans, comparatively higher household incomes than many nearby parishes, and frequent use of regional news/weather and storm-preparedness updates are factors that tend to support high mobile and social media adoption.

User statistics (penetration / share of residents using social media)

• No robust, parish-specific social media penetration dataset is publicly available at the county level from major national survey programs; most high-quality measurement is reported at the U.S. and state level rather than for individual parishes.
• Benchmarks used to contextualize Saint Tammany typically rely on national survey findings:
  • About 7 in 10 U.S. adults use social media (usage varies by age), according to the Pew Research Center report on U.S. social media use.
  • A large majority of U.S. adults use YouTube, and major platforms such as Facebook and Instagram remain widely used, per the same Pew source.
• In practice, local planning and public information efforts in Saint Tammany commonly assume broad adult reach via Facebook, YouTube, and Instagram, consistent with national patterns for suburban counties in large metro areas.

Age group trends (who uses social media most)

• Age is the strongest predictor of social media use in high-quality U.S. survey data:
  • Adults ages 18–29 and 30–49 show the highest social media usage rates, while 65+ shows the lowest overall usage, per Pew Research Center.
  • Platform-by-platform differences are substantial in Pew’s findings: younger adults over-index on visually oriented and creator-centric platforms (notably Instagram, TikTok, Snapchat), while middle-aged and older adults maintain heavier Facebook usage.
• For Saint Tammany’s population mix (suburban, family-oriented communities plus retiree presence), these national age patterns generally translate into:
  • High Facebook reach among 30+
  • Higher Instagram/TikTok intensity among 18–29
  • Lower adoption and lighter usage among 65+ relative to younger cohorts

Gender breakdown

• County-specific gender splits by platform are not published in standard public datasets at the parish level.
• Nationally, gender differences tend to be smaller than age differences for overall social media use; however, platform preferences vary. Pew’s platform tables provide the clearest public benchmark for U.S. adults by demographic group (including gender) in its social media use report.
• Applied to Saint Tammany, the most reliable statement supported by public data is that gender effects are secondary to age and life-stage (students/young adults, working-age households, retirees) in explaining platform mix.

Most-used platforms (with percentages where possible)

Because parish-level platform penetration percentages are not available from major public surveys, the most defensible percentages are U.S.-level benchmarks:

• YouTube: used by a large majority of U.S. adults (Pew reports YouTube as the top platform in the U.S.). Source: Pew Research Center, Social Media Use.
• Facebook: used by a substantial share of U.S. adults and tends to skew older than Instagram/TikTok. Source: Pew Research Center.
• Instagram: widely used, strongest among younger adults. Source: Pew Research Center.
• TikTok: sizable adoption, concentrated among younger adults. Source: Pew Research Center.
• Nextdoor (local neighborhood social platform): often relevant in suburban counties for hyperlocal alerts and recommendations, though comprehensive public penetration estimates are not generally available at the parish level; its usage is typically evidenced through local community participation rather than standardized survey measurement.

Behavioral trends (engagement patterns / preferences)

• Utility-driven engagement is prominent in suburban parishes: weather events, traffic incidents, school and public safety updates, and local government communications tend to drive shares, comments, and repeat visits. This aligns with broader findings that social media is commonly used for information, community updates, and video consumption; Pew’s research on platform use and news use provides national context (see Pew Research Center journalism and news research for related benchmarking).
• Video-first consumption is a cross-platform norm: YouTube and short-form video features (Instagram Reels, TikTok) typically capture high attention time, consistent with YouTube’s broad reach in Pew’s measurements (Pew social media use).
• Platform role separation is common:
  • Facebook: community groups, local events, marketplace activity, and long-standing networks (strong among 30+).
  • Instagram/TikTok: lifestyle content, local dining/leisure discovery, creators, and short-form entertainment (strongest among younger adults).
  • YouTube: how-to content, local interest topics, news clips, and longer-form video across age groups.
• Engagement skews toward “lurking” over posting for many adults: national survey research regularly finds that many users consume and react more than they create original posts; this dynamic typically appears in local communities as higher viewing and sharing than original content production, especially outside the youngest adult cohorts.

Saint Tammany Parish does not typically maintain birth, death, marriage, or divorce certificates at the parish level; these vital records are maintained by the State of Louisiana through the Louisiana Department of Health, Vital Records Registry. Requests and requirements are published on the official Vital Records pages for Birth and Death Certificates and related services (LDH). Adoption records are generally sealed under Louisiana law and are handled through state processes and the courts rather than general public-record access.

Associate-related public records at the parish level commonly include court filings and clerk records (civil, criminal, family-related proceedings, succession/probate, and related documents) maintained by the St. Tammany Parish Clerk of Court. Property and conveyance records that can reflect family or associate relationships (deeds, mortgages, liens, successions) are also accessed through the Clerk of Court’s land records resources. Certain recorded notices and parish administrative information may be available through the St. Tammany Parish Government.

Public access is generally provided through online search portals where offered by the relevant office, and through in-person requests at the Clerk of Court and other parish offices during business hours. Privacy restrictions commonly apply to sealed court matters, juvenile records, adoption-related information, and state-issued vital records, which are typically limited to eligible requesters and require identity and relationship documentation.

Types of records available

• Marriage license and marriage certificate (local record): Issued by the Saint Tammany Parish Clerk of Court as a marriage license; after the ceremony the officiant returns the completed license for recording, producing the parish’s recorded marriage record.
• Marriage records (state index/certification): The Louisiana Department of Health (LDH), Vital Records Registry maintains statewide marriage records and issues certified copies within its statutory coverage period.
• Divorce decrees and divorce case records (court records): Divorce records are maintained as civil court case files by the Clerk of Court. The final judgment is commonly referred to as a Judgment of Divorce or divorce decree.
• Annulments (court records): Annulments are maintained as civil court case files by the Clerk of Court and typically conclude with a Judgment of Annulment (or judgment declaring the marriage null).

Where records are filed and how they can be accessed

• Marriage licenses/recorded marriages (parish level):
  • Filed/recorded with: Saint Tammany Parish Clerk of Court (Marriage License/Recording function).
  • Access: Copies are typically obtained through the Clerk of Court (in person or by written request, depending on the office’s procedures). Searches may require names and an approximate date of marriage.
• Marriage certificates (state level):
  • Filed with/maintained by: LDH Vital Records Registry.
  • Access: Certified copies are requested from LDH Vital Records (by mail and through approved service channels). LDH applies statewide rules on eligibility and identification.
• Divorce and annulment judgments (parish level):
  • Filed with: Saint Tammany Parish Clerk of Court in the civil division as a case record; judgments are part of the case file and may also be reflected in court minutes and related filings.
  • Access: Case files and certified copies are typically requested from the Clerk of Court. Access can involve case number, party names, and the approximate filing or judgment date. Some records may be viewable through court record systems or in-office terminals where available, subject to redaction and restriction rules.
• Divorce verification (state level, limited):
  • Louisiana generally does not issue a statewide “divorce certificate” in the same manner as marriage certificates through vital records; divorces are principally documented through court judgments maintained by the parish Clerk of Court.

Typical information included in these records

• Marriage license / recorded marriage record:
  • Full names of both parties (often including prior/maiden names where provided)
  • Dates of birth/ages, places of birth (varies by form/version)
  • Addresses/residences at time of application
  • Date and place of marriage ceremony
  • Name and authority of the officiant; officiant’s signature
  • Witness information (commonly names/signatures, depending on form)
  • License number, issuance date, and recording information
• Divorce case file / divorce judgment:
  • Names of the parties, docket/case number, and court division
  • Filing date(s), pleadings (petition/complaint), and service/appearance information
  • Grounds asserted under Louisiana law (as reflected in filings)
  • Judgment of Divorce date and terms
  • Orders addressing custody, visitation, child support, spousal support, community property partition, and name restoration (as applicable to the case)
• Annulment case file / annulment judgment:
  • Names of the parties, docket/case number, and court division
  • Alleged legal basis for nullity (as pleaded)
  • Judgment of Annulment and any related orders (custody/support/property issues may still be addressed depending on circumstances)

Privacy or legal restrictions

• Marriage records:
  • Basic marriage record information is generally treated as public record at the parish level, but certified copies commonly require identity verification and may be limited to eligible requesters under state vital records rules when requested from LDH Vital Records.
• Divorce and annulment records:
  • Court records are generally public, but Louisiana courts can restrict access to specific filings or information by sealing orders or by operation of law in certain categories (for example, some sensitive family-law materials).
  • Minor-related information and certain personal identifiers (such as Social Security numbers) are subject to confidentiality rules and redaction practices.
  • Protective orders, psychological evaluations, and certain custody-related reports may be restricted from general public inspection depending on how they are filed and ordered by the court.
• Certified copies and identification requirements:
  • Clerks of court and LDH may require government-issued identification and may limit issuance of certified copies to persons with a recognized legal interest, particularly for state-issued vital records.

Saint Tammany County (parish) is in southeastern Louisiana on the north shore of Lake Pontchartrain, across from the New Orleans metro area. It is one of the state’s largest and fastest-growing suburban parishes, with a population of roughly 270,000–280,000 (recent U.S. Census estimates). Communities such as Covington (parish seat), Mandeville, Slidell, Lacombe, Madisonville, Abita Springs, and Pearl River combine suburban neighborhoods, small-town centers, and lower-density rural areas. The parish’s growth and its proximity to major job centers in Orleans and Jefferson Parishes shape commuting patterns, school enrollment, and housing demand.

Education Indicators

Public schools (count and names)

Saint Tammany Parish Public Schools (STPPS) operates the parishwide public school system, with dozens of campuses (roughly 50+ schools across elementary, junior high, high school, and alternative programs). A current, authoritative directory (including official school names) is maintained on the district’s site via the STPPS school directory (St. Tammany Parish Public Schools).
Note: A single “number of public schools” figure varies by year as campuses open/close or are reconfigured; the STPPS directory is the most current source.

Student–teacher ratios and graduation rates

• Student–teacher ratio: Public school ratios for the parish are commonly reported in the mid-to-high teens (students per teacher), consistent with Louisiana suburban districts. For the most recent official district/school ratios, the state publishes school profiles through the Louisiana Department of Education (LDOE) School Report Cards (Louisiana School Report Cards).
• Graduation rate: The parish’s high school graduation performance is reported annually through LDOE accountability. Recent district graduation rates have generally been above the Louisiana statewide average, with exact annual values and school-by-school rates available in the LDOE report cards linked above.
  Proxy note: Where a single parishwide “current year” figure is needed, LDOE accountability reporting is the standard reference; locally summarized values often lag the most recent LDOE release.

Adult education levels

Using the most recent American Community Survey (ACS) “5-year” profile for Saint Tammany Parish (standard for county-level educational attainment):

• High school diploma or higher (age 25+): approximately 90%+
• Bachelor’s degree or higher (age 25+): approximately 30%+
  These indicators are available in ACS Educational Attainment (DP02/S1501) tables via the U.S. Census Bureau’s data portal (U.S. Census Bureau data.census.gov).
  Context: Educational attainment in Saint Tammany generally exceeds Louisiana statewide averages, reflecting its suburban professional workforce and commuter ties to the New Orleans region.

Notable programs (STEM, vocational, AP)

• Advanced Placement (AP), dual enrollment, and career pathways are commonly offered through parish high schools; program availability is typically school-specific and documented through individual school course catalogs and LDOE school profiles.
• Career and Technical Education (CTE)/workforce training: Louisiana’s statewide CTE framework includes industry-based credentials and pathway programs; local implementation is reflected in district offerings and high school academies where present. LDOE provides the statewide structure and credential reporting (LDOE pathways and career education).
• STEM: STEM coursework and extracurriculars (robotics, engineering, computer science) are commonly reported by schools and may vary by campus; district and school webpages provide the most current program lists.

School safety measures and counseling resources

• Safety measures: Districts in Louisiana generally employ campus security procedures such as controlled access, visitor management, drills, and coordination with school resource officers where applicable. The most definitive statements are found in STPPS policy updates and school handbooks posted through STPPS and individual school sites (STPPS official site).
• Counseling resources: Public schools typically provide school counselors and may provide school-based mental/behavioral health supports; service levels vary by school. LDOE and district guidance commonly reference counseling services, crisis response protocols, and referral processes in school handbooks and student services pages.

Employment and Economic Conditions

Unemployment rate (most recent)

The most recent official unemployment estimates for the parish are published by the U.S. Bureau of Labor Statistics (LAUS) and state labor market reporting. Recent years have typically shown Saint Tammany with unemployment near the low-to-mid single digits (often below Louisiana’s statewide rate). The definitive series is available via BLS Local Area Unemployment Statistics (BLS LAUS unemployment data) and Louisiana labor market dashboards (Louisiana Workforce Commission).
Proxy note: Month-to-month rates vary; annual averages are generally used for “most recent year.”

Major industries and employment sectors

Employment is anchored in:

• Healthcare and social assistance (regional hospitals/clinics and outpatient services)
• Retail trade and accommodation/food services (serving suburban and tourist traffic)
• Educational services (public schools and related services)
• Construction and real estate (driven by housing growth)
• Professional, scientific, and technical services and administration/support (including commuters working in metro New Orleans)
• Public administration (parish/municipal services)
  Sector composition is documented in ACS “Industry” tables and regional labor market summaries (ACS industry data).

Common occupations and workforce breakdown

Common occupation groups include:

• Management, business, science, and arts occupations
• Sales and office occupations
• Service occupations (healthcare support, protective services, food service)
• Construction, extraction, and maintenance
• Production, transportation, and material moving
  These distributions are available through ACS occupation tables (e.g., S2401) on data.census.gov.
  Context: The parish often shows a comparatively larger professional/managerial share than many Louisiana parishes, consistent with higher educational attainment and metro-area commuting.

Commuting patterns and mean commute time

• Commuting mode: The parish is largely auto-commuter oriented, with a high share driving alone, smaller shares carpooling, and limited transit share compared with dense urban parishes.
• Mean commute time: Typical mean commute times are generally in the high 20s to low 30s minutes, reflecting cross-lake and interstate commuting patterns (I‑10, Causeway connections to the south shore).
  ACS commuting tables (S0801) provide the most recent parish values (ACS commuting data).

Local employment vs out-of-county work

A substantial portion of the workforce commutes out of the parish, particularly toward Orleans and Jefferson Parishes and other New Orleans–area job centers. This pattern is supported by:

• ACS “Place of Work” commuting characteristics
• Federal commuter flow products (e.g., LEHD/LODES) where available for origin-destination analysis (Census LEHD)
  Proxy note: Public summaries frequently describe Saint Tammany as a major residential base for the New Orleans metro workforce; precise “out-of-county share” varies by dataset year.

Housing and Real Estate

Homeownership and rental share

Saint Tammany typically has a high homeownership rate compared with urban parishes in the region, with owner-occupied housing commonly around the low- to mid-70% range and the remainder renter-occupied. The most current official estimates are in ACS housing occupancy tables (DP04) (ACS housing data).

Median property values and recent trends

• Median owner-occupied home value: ACS 5-year estimates generally place the parish median in the mid-$200,000s to low-$300,000s range (exact value depends on the latest ACS release year and inflation context).
• Recent trends: The parish followed broader U.S. and Gulf South patterns: rapid appreciation during 2020–2022, with slower growth and more normalization afterward relative to peak pandemic-era increases.
  For official medians, use ACS DP04; for market trend context, regional MLS summaries and Federal Housing Finance Agency (FHFA) price indexes are commonly referenced (FHFA House Price Index).
  Proxy note: Transaction-based medians from MLS sources are not always publicly reproducible; ACS provides the most consistent public series.

Typical rent prices

• Median gross rent: ACS 5-year estimates commonly place median gross rent in the $1,100–$1,500 range depending on the year and submarket, with higher rents closer to lakefront and major retail/office corridors and lower rents in more rural areas. Official values appear in ACS DP04 (ACS rent estimates).

Types of housing

• Predominantly single-family detached housing in subdivisions and suburban corridors (Mandeville/Covington/Slidell growth areas)
• Apartments and townhomes clustered near commercial centers and along key routes (I‑10 interchanges, major arterials)
• Rural lots and lower-density homes in unincorporated areas, including larger parcels and semi-rural neighborhoods
  Housing stock composition by structure type is available via ACS (DP04).

Neighborhood characteristics (schools and amenities)

• Many residential areas are organized around school attendance zones, with proximity to public schools, parks, and retail nodes influencing neighborhood development.
• Higher-density multifamily tends to be nearer employment centers, shopping corridors, and interstate access, while rural neighborhoods emphasize lot size and privacy with longer drive times to services.
  Proxy note: Parishwide neighborhood characteristics are not captured in a single official statistic; the pattern is consistent with land use and development geography in the northshore suburbs.

Property tax overview (rate and typical cost)

Louisiana property taxes are generally assessed on taxable value (after homestead exemption, where applicable) and levied by multiple local millages (parish, schools, municipalities, special districts).

• Effective property tax rates in Louisiana are often around ~0.5%–1.0% of market value (varies substantially by location and exemptions), with Saint Tammany commonly near the middle of that range for many owner-occupied homes.
• A typical annual homeowner tax bill depends on assessed value, exemption status, and local millages; parish assessor and tax collector sources provide the definitive millage and billing context. Official parish references include the St. Tammany Parish Assessor (St. Tammany Parish Assessor) and the Louisiana Tax Commission overview of assessment practices (Louisiana Tax Commission).
  Proxy note: A single “average tax bill” figure is not consistently published in a comparable way across Louisiana parishes; assessor and tax roll data are the authoritative sources for local millage totals and example bills.
