Email Usage in Boulder County

Boulder County, CO snapshot (estimates)

  • Population: ~330,000.
  • Email users: ~265,000–285,000 residents (driven by near-universal adoption among adults and CU Boulder’s large student base).
  • Age distribution of email users:
    • 18–29: ~23–26% (usage 95–99%)
    • 30–49: ~30–34% (95–99%)
    • 50–64: ~24–27% (90–95%)
    • 65+: ~15–20% (80–90%)
  • Gender split: ~50/50 male/female; usage differences are negligible. Nonbinary users present but a small share in available surveys.
  • Digital access trends:
    • Broadband subscription: roughly 94–96% of households; computer access ~96–98%.
    • Smartphone-only internet: ~8–12% of households.
    • Gigabit fiber widely available in Longmont (municipal NextLight) and much of Boulder/Louisville/Lafayette via private ISPs; foothill and mountain communities rely more on DSL/WISPs, with slower speeds and occasional reliability issues.
    • Strong 5G coverage along the US‑36 corridor; campus and coworking spaces provide dense Wi‑Fi.
  • Density/connectivity facts: County population density ≈450 people/sq mi; most residents live in the Boulder–Longmont urban corridor where multiple gigabit options and 200+ Mbps median city speeds are common; coverage thins in western, mountainous areas.

Note: Figures combine ACS “Computer and Internet Use” and Pew/National email adoption benchmarks scaled to Boulder County’s demographics.

Mobile Phone Usage in Boulder County

Below is a concise, county-focused snapshot based on 2024–2025 public data patterns (Census/ACS, FCC maps, carrier announcements, and national research). Figures are reasoned estimates; exact, county-specific measurements are rarely published.

Headline estimate of users

  • Population: about 330k.
  • Adults (18+): roughly 270k. With high income/education and an urban/suburban footprint, adult smartphone adoption is likely 92–94% (above Colorado’s statewide average), yielding about 250k–255k adult smartphone users.
  • Youth: 13–17-year-olds likely 19k–22k smartphone users; 10–12-year-olds another 4k–6k with phones.
  • Total smartphone users: approximately 273k–288k countywide. Total active mobile lines (phones + wearables + hotspots) will be higher due to multi-line and device add‑ons.

Demographic patterns that shape usage

  • University effect: CU Boulder’s ~tens of thousands of students make 18–29 the heaviest mobile segment, with near-universal smartphone access, high data use (video, social, messaging), and strong demand for campus/downtown capacity and small-cells.
  • Affluence/education: Higher household income and education than the state average correlate with:
    • Faster upgrade cycles, higher 5G device mix, and strong iOS share.
    • Greater use of wearables and eSIM/dual-SIM for travel and work.
  • Older adults: Above-state-average adoption among 65+ due to income/education and telehealth usage, but still the cohort most sensitive to coverage in foothills and canyons.
  • Equity gaps: Pockets in Longmont/east county (larger Latino population, more service/industrial workers) show higher prepaid and family-plan use and more reliance on Wi‑Fi to manage costs as the ACP program sunset.
  • Work/commute: Heavy hybrid/remote work increases daytime mobile data and hotspot use along the US‑36 and SH‑119 corridors; event-driven surges around CU, downtown Boulder/Pearl Street, and at recreation access points (trailheads, Eldora via Nederland).

Digital infrastructure and coverage

  • 5G footprint: Strong mid‑band 5G across the flatlands (Boulder, Longmont, Louisville, Lafayette, Superior) from all three nationals. T‑Mobile’s 2.5 GHz and Verizon/AT&T C‑Band are common in town; speeds taper heading into the foothills.
  • Foothills/canyons: Nederland, Lyons, and canyon roads (Boulder, Left Hand, St. Vrain) have notable dead zones and capacity constraints—coverage is highly topography‑dependent. Public safety Band 14 (FirstNet) improves resilience but does not eliminate gaps.
  • Small cells and venues: Dense small-cell/DAS around CU campus, stadiums, The Hill, and parts of downtown Boulder to handle event traffic and signal penetration limits in energy‑efficient buildings.
  • Backhaul/fiber: Robust metro fiber from Zayo (Boulder-based), Lumen, Comcast, and municipal networks (notably Longmont’s NextLight) supports macro, small cell, and enterprise backhaul; CDOT fiber along key corridors. This fiber depth is stronger than most Colorado counties.
  • Fixed Wireless Access (FWA): Widely offered east of the foothills (T‑Mobile, Verizon), with take‑up among renters and students. Overall reliance is moderated by strong cable/fiber options, especially in Longmont.
  • Power resiliency: Post‑Marshall Fire hardening improved backup power and public-safety coverage at select sites; wind/wildfire PSPS conditions remain a risk for sites near the Wildland–Urban Interface.

How Boulder County differs from Colorado overall

  • Higher adoption and newer devices: Smartphone penetration, 5G device mix, and wearables/eSIM usage are all above the state average, driven by students, tech workers, and higher incomes.
  • Better urban/suburban 5G: Boulder’s flatland cities have denser macro/small‑cell builds and more mid‑band 5G than many Colorado counties. The state’s rural/western areas still see LTE‑only pockets; Boulder’s gaps are more localized to canyons/foothills.
  • Less “mobile-only” home internet: Thanks to cable and municipal fiber (e.g., NextLight), a smaller share of households rely solely on cellular for home broadband compared with the statewide mix, though FWA is attractive in apartments and student housing.
  • Different congestion patterns: Traffic surges skew to campus events, Pearl Street, and recreation corridors (Eldora/Peak-to-Peak, trailheads) rather than the resort/tourism peaks typical of mountain counties.
  • Equity picture: Digital divide exists but is smaller in scale than in lower-income Colorado counties; targeted outreach (multilingual support, prepaid affordability) is most relevant in Longmont/east county.

Implications and watch areas

  • Capacity management: Continue small-cell densification around CU/downtown and along US‑36/SH‑119; add seasonal capacity near Nederland/Eldora and popular trailheads.
  • Coverage resiliency: Prioritize backup power and hardening for foothills/canyon sites; expand Band 14 and mid‑band 5G where feasible.
  • Inclusion: Support prepaid/low-cost plans and device financing in Longmont/east county; maintain robust public Wi‑Fi in libraries, transit hubs, and civic spaces.
  • Buildings: Encourage Wi‑Fi calling and indoor systems (DAS/private 5G) in energy‑efficient or shielded structures to offset penetration losses.
