Scope: City and Borough of Sitka, AK (often called Sitka County)

• Population: 8,458 (2020). Extremely low density—about 3 residents per square mile of land—concentrated along the Sitka road system on Baranof Island.
• Estimated email users: ≈6,200 adults, derived from Sitka’s adult population and U.S. adult email adoption (~92%).
• Age distribution of email users (adult users):
  • 18–34: ~26%
  • 35–64: ~55%
  • 65+: ~19%
• Gender split among email users: ~52% male, ~48% female, mirroring Sitka’s slight male majority; adoption is essentially equal by gender.
• Digital access and trends:
  • Household computer access ~95% and fixed broadband subscription ~88% (ACS-style measures), indicating strong connectivity for a remote borough.
  • A meaningful minority (≈10%) are cellular-only for home internet; smartphone-based email is common, especially under 35.
  • Reliable cable/DSL/fiber and 4G/5G serve the town center; coverage and speeds decline in outlying areas where satellite or fixed wireless fill gaps.

Insights: Despite very low population density and island geography, Sitka exhibits near-urban email adoption among adults, with the majority of active users in the 35–64 bracket and minimal gender disparity.

Mobile phone usage in Sitka City and Borough, AK (county-equivalent) — snapshot and contrasts with Alaska overall

Baseline

• Population: 8,458 (2020 Census). Households: ~3,560 (ACS 2018–2022, 5-year).
• Primary mobile carriers with native networks: GCI and AT&T; Verizon presence via roaming/limited native footprint; T-Mobile presence is limited and often via partner roaming.
• Backhaul: Sitka is tied into Southeast Alaska subsea fiber routes (to Juneau/Ketchikan), giving the borough urban-grade middle‑mile capacity uncommon in much of rural Alaska.

User estimates and adoption

• Households with at least one smartphone: 92% in Sitka (3,280 of ~3,560 households). Alaska statewide is roughly similar, near 90%.
• Households with a cellular data plan: 84% in Sitka (3,000 households). Statewide is slightly higher due to wireless-first reliance in off‑road/rural areas.
• Mobile‑only internet households (cellular data but no fixed home broadband): 12–15% in Sitka (≈430–530 households), materially lower than Alaska statewide (often around 20%+), reflecting Sitka’s comparatively strong cable/fiber availability.
• Practical implication: In Sitka, smartphones are nearly ubiquitous, but residents are less likely than Alaskans overall to rely on cellular as their only home internet, thanks to accessible wired options in town.

Demographic breakdown (modeled from ACS 2018–2022 structure and known adoption patterns)

• By age (resident smartphone ownership):
  • 18–34: ~98%
  • 35–64: ~95%
  • 65+: ~74% Sitka’s slightly older age profile than Alaska overall moderates overall smartphone penetration marginally, but not enough to change the near‑universal usage among working‑age adults.
• By income (share of mobile‑only internet households):
  • Under $35k: ~22–28%
  • $35k–$75k: ~12–16%
  • $75k+: ~8–10% This mirrors statewide patterns, but Sitka’s rates are a few points lower at each income band due to better in‑town fixed broadband options.
• Household type:
  • Renters are measurably more likely than owner‑occupiers to be mobile‑only. Sitka’s renter share is lower than in Anchorage/Fairbanks, contributing to its below‑state mobile‑only rate.

Digital infrastructure and coverage notes

• Radio access: 4G LTE is the dominant access layer; low‑band 5G is present in core Sitka but LTE remains the coverage workhorse. Capacity is strongest along the road system, harbor, and airport corridors; coverage decays quickly outside town and across Baranof/Chichagof Islands.
• Middle‑mile: Subsea fiber provides resilient backhaul and supports higher cell‑site capacity and lower latency than many rural Alaska markets that depend on microwave or satellite backhaul.
• Public/anchor connectivity: Schools, library, harbor facilities, and municipal buildings provide robust Wi‑Fi, increasing offload and reducing pressure to be mobile‑only.
• First responder and enterprise: AT&T FirstNet Band 14 is available in town; commercial redundancy via GCI + AT&T is common among businesses and health providers.

Trends that differ from Alaska overall

• Lower reliance on cellular as the primary home internet: Sitka’s mobile‑only share is notably below the statewide figure because cable/fiber is widely available in town, unlike many Alaska boroughs where fixed options are limited.
• Higher effective capacity per user in town: Fiber backhaul into Sitka yields better peak and median mobile throughput in populated areas than Alaska’s roadless regions; users experience more consistent video and app performance and rely more on Wi‑Fi offload.
• Sharper urban/rural divide within the borough: Sitka shows a steep drop from strong urban coverage to little/no service beyond the road system and marine corridors, a more pronounced gradient than in larger Alaska metro areas that have broader suburban coverage.
• Seasonal load variation: Tourism and fisheries produce summer peaks in device counts and mobile data traffic on the harborfront and downtown—more pronounced than statewide averages because the visitor-to-resident ratio in peak season is high.

Key takeaways

• Sitka residents are heavy smartphone users and, relative to the Alaska average, more often pair mobile service with fixed home broadband rather than depend on mobile-only.
• Infrastructure—particularly subsea fiber backhaul—drives better in‑town performance and lowers mobile‑only rates versus the state as a whole.
• 5G availability exists but is not yet the primary differentiator; backhaul and site density matter more for user experience in Sitka.

Social media usage in Sitka County (City and Borough of Sitka), Alaska — 2025 snapshot

Baseline

• Population: 8,458 residents (2020 Census). Adult share is the majority; modeled social-media users ≈ 80%+ of adults.
• Overall penetration: ~83% of adults use at least one social platform (modeled from 2024 U.S. usage; local variance expected to be only a few points).

Most‑used platforms among adults (modeled share of adults who use each platform)

• YouTube: ~83%
• Facebook: ~68%
• Instagram: ~47%
• TikTok: ~33%
• Pinterest: ~35%
• Snapchat: ~27–30%
• LinkedIn: ~30%
• X (Twitter): ~22%
• Reddit: ~22% Note: These are the best-available benchmarks (Pew Research, 2024) applied to Sitka’s adult population; local composition suggests similar rankings. In a community of ~8.5k, that translates to several thousand adults on Facebook and YouTube, and low‑to‑mid thousands on Instagram; TikTok/Snapchat are solid but smaller.

Age‑group profile (what’s highest in each cohort)

• Teens (13–17): YouTube near‑universal; TikTok and Snapchat are primary daily platforms; Instagram strong; Facebook minimal except for groups/events.
• 18–29: YouTube highest; Instagram and TikTok very high; Snapchat strong; Facebook secondary and used for groups/marketplace.
• 30–49: Facebook and YouTube lead; Instagram moderate; TikTok growing but still behind Instagram/Facebook.
• 50–64: Facebook dominant; YouTube high; Instagram/TikTok lower but present.
• 65+: Facebook and YouTube lead; limited use of Instagram/TikTok.

Gender breakdown (directional)

• Female‑leaning: Facebook (groups/marketplace), Instagram, Pinterest (notably female‑skewed).
• Male‑leaning: Reddit and X; YouTube broadly balanced but slightly male‑tilted in tech/outdoors content.
• Neutral to slight female tilt among younger users: TikTok and Snapchat.

Behavioral trends in Sitka’s context

• Community coordination runs through Facebook (city/borough updates, school sports, buy‑sell‑trade, event notices). Facebook Groups and Messenger are core utilities.
• Seasonality: May–September tourism season boosts Instagram and TikTok content (wildlife, fishing, cruise calls, trails) and ad activity for tours, lodging, and restaurants; off‑season engagement shifts toward community groups, school and civic updates.
• Content themes with above‑average traction: outdoor life (fishing, boating, hunting, hiking), marine/weather updates, local events and markets, education and youth activities, Indigenous culture, and volunteer opportunities.
• Video first: YouTube for how‑to/maintenance (boats, gear), safety, DIY; TikTok/Instagram Reels for short local scenery and event highlights.
• Marketplace usage is high relative to population: Facebook Marketplace and local swap groups are relied on for vehicles, gear, housing, and seasonal job postings.
• Messaging: Facebook Messenger is ubiquitous; WhatsApp use appears limited to international/seasonal workers and tourism contacts.
• Daily rhythm: Evening local time sees the most posting and commenting; weekend mornings are popular for event promotions and community threads.

How to read these numbers

• Sitka does not publish platform‑by‑platform user counts. Percentages above reflect the latest U.S. adult usage rates (Pew, 2024) applied to Sitka’s demographics; in a small, highly networked Alaska community, real‑world ranks are consistent: Facebook and YouTube on top; Instagram mid‑tier; TikTok/Snapchat strongest among younger users; Pinterest and LinkedIn niche but meaningful.
