FCC Broadband Data Collection / Signal diagnostic Snapshot Jul 11, 2026

What they say
vs what you get

The national broadband map is built from what providers say they offer. A block is “served” when a company reports it could connect you - at the fastest tier it advertises, not the speed that actually arrives at night. This is a diagnostic of where that gap runs widest.

Real Coverage, community, and competition are the FCC's own BDC December 2025 data. Illustrative The single-provider vignettes and the measured-speed characterizations model documented patterns - marked throughout. See Methodology.

Three optimisms

01 / Why the map says you're covered

Nobody has to lie for the broadband map to overstate reality. The overstatement is built into three definitions - each defensible on its own, compounding into a picture rosier than the one you meet when you actually try to buy service. Every claim in this section is documented.

  1. Fault 01

    “Could serve” counts as served

    A location is listed as covered when a provider says it could begin service within ten business days of a request - even if nobody there subscribes, the build-out quote runs into the thousands, or a line was never actually installed.

    Real The BDC availability standard is provider self-report of where service is or could be made available, not where it is built, sold, and running.

  2. Fault 02

    Advertised speed, not measured speed

    Filings carry each provider's maximum advertised tier. What actually arrives at 8 p.m. on a congested node is a different number entirely - measured by a separate program, never shown on the coverage map.

    Real The FCC's Measuring Broadband America program exists precisely because the availability filings report advertised, not measured, throughput.

  3. Fault 03

    One qualifying spot can flag a whole area

    The retired Form 477 marked an entire census block “served” if a single location in it could get service. The BDC moved to location-level reporting in 2022 - an improvement - but the data is still self-reported and the underlying Location Fabric still misses units.

    Real Form 477's block-level overstatement is the documented reason Congress ordered the more granular Broadband Data Collection.

The gap, once someone measured it
FCC · 2019 reported lacking 25/3
claimed
~21M
Microsoft telemetry not using broadband speeds
measured
~120M

In 2019 the FCC reported ~21 million Americans lacked 25/3 access. Microsoft, reading its own service telemetry, estimated ~120 million-plus were not actually using the internet at broadband speeds - the single most-cited illustration of the availability-versus-reality gap.

The coverage gap

02 / When satellite carries the map

By the map's own numbers, 99.99% of the country can get 100 / 20 Mbps - all but a rounding error. But that figure counts a low-orbit satellite dish as a broadband option. Strip satellite out and keep only a wire to the home, and the served share falls to 92.76%.

11.8M
Real locations with no wired 100 / 20 Mbps option - counted as "served" on the all-technology map

Real Unit-weighted over the FCC Location Fabric (162,419,094 broadband-serviceable locations), December 2025 BDC. "Available" means a provider filed the location as served or serviceable, not that service is installed and sold.

And the gap is not evenly shared

The share of each community without a wired 100 / 20 Mbps option. Urban America is effectively wired; the gap opens in rural counties and widens again on Tribal lands, where terrain, jurisdiction, and the thinnest build-out returns compound.

The same figures, in a table

Tribal lands 25.7% 22.7%

Real The FCC's own BDC December 2025 shares, unit-weighted over the Location Fabric and split by community type. The Tribal gap is the widest and the most persistent in the data.

By technology

03 / What is available, and to whom

Break the map apart by technology and the headline dissolves. Low-orbit satellite is filed at nearly every location, which is why the all-in number reads like full coverage. The wire that actually lands a low-latency, uncapped line - fiber - reaches barely half. Copper, still on the map, clears 100/20 almost nowhere.

One option, or none

04 / How many wires actually reach you

A green dot on the coverage map says available. It does not say how many companies you can actually choose between. Counting the wired providers filed at each location, this is how much of the country has real competition - and how much has one line, or none.

30.1% One wired option, or none

of U.S. locations - about 35.1 million - have a single wired broadband provider or none at all. Where one company files, the advertised price is simply the price: no competitor to undercut it, and the map still reads as covered.

Locations by wired-provider count Real
No wired provider 5.27% One wired provider 24.85% Two or more 69.88%
4.51% of locations get 100 / 20 Mbps only from satellite - no terrestrial line clears it
59.9% have fiber available - the one wire that keeps its advertised speed

Real Location-weighted over the 116,465,390 locations that appear in at least one fixed BDC filing (satellite is filed nationwide, so this is effectively every serviceable location). A "wired provider" is a Copper, Cable, or Fiber provider filing the location; "one or none" counts locations with a single wired provider or zero.

Illustrative The vignettes below are archetypes, not named counties with fabricated provider counts - each dramatizes a documented single-provider pattern the numbers above measure in aggregate. The state map shows where they concentrate.

  1. 01

    A ranching county in the Mountain West

    Interior West / Geostationary satellite

    Terrestrial providers file the county as “served” from a tower miles away. The only line you can actually order is a satellite dish with a 600 ms round-trip.

  2. 02

    A Mississippi Delta parish

    Deep South / One cable incumbent

    A single cable company holds the whole footprint. No competitor files here, so the advertised price is simply whatever the incumbent lists.

  3. 03

    An Appalachian hollow

    Central Appalachia / DSL over aging copper

    The map shows 25 Mbps DSL. On a copper loop this long the line syncs at a fraction of that - but it still counts as covered.

  4. 04

    A high-desert Tribal community

    Southwest / Fixed wireless, line-of-sight

    Service depends on an unobstructed path to a distant tower. Where terrain blocks it, the household is counted served and gets nothing.

  5. 05

    An exurban new-build subdivision

    Sun Belt fringe / One provider, waitlisted

    The developer wired a single provider. It sits on the map at gigabit - with a months-long install backlog.

Where you have a choice

05 / One wired option, by state

The share of each state's locations with a single wired provider - or none - filed at the current benchmark. Competition is not a rural-or-urban story alone: it turns on who built the wire. Alaska and West Virginia run deepest, but so does Massachusetts, where one cable incumbent holds town after town.

Alabama: 33.41% one wired provider or none Alaska: 64.36% one wired provider or none Arizona: 26.38% one wired provider or none Colorado: 18.54% one wired provider or none Florida: 19.98% one wired provider or none Georgia: 24.88% one wired provider or none Indiana: 27.38% one wired provider or none Kansas: 31.59% one wired provider or none Maine: 29.94% one wired provider or none Massachusetts: 45.18% one wired provider or none Minnesota: 26.39% one wired provider or none New Jersey: 36.23% one wired provider or none North Carolina: 27.76% one wired provider or none North Dakota: 44.55% one wired provider or none Oklahoma: 41.54% one wired provider or none Pennsylvania: 36.04% one wired provider or none South Dakota: 44.38% one wired provider or none Texas: 28.5% one wired provider or none Wyoming: 39.58% one wired provider or none Connecticut: 16.08% one wired provider or none Missouri: 32.41% one wired provider or none West Virginia: 59.03% one wired provider or none Illinois: 25.21% one wired provider or none New Mexico: 31.32% one wired provider or none Arkansas: 40.45% one wired provider or none California: 24.56% one wired provider or none Delaware: 44.47% one wired provider or none District of Columbia: 5.79% one wired provider or none Hawaii: 20.22% one wired provider or none Iowa: 31.21% one wired provider or none Kentucky: 37.97% one wired provider or none Maryland: 35.37% one wired provider or none Michigan: 39.73% one wired provider or none Mississippi: 38.5% one wired provider or none Montana: 47.44% one wired provider or none New Hampshire: 18.99% one wired provider or none New York: 37.65% one wired provider or none Ohio: 27.26% one wired provider or none Oregon: 25.14% one wired provider or none Tennessee: 21.75% one wired provider or none Utah: 18.94% one wired provider or none Virginia: 37.15% one wired provider or none Washington: 36.24% one wired provider or none Wisconsin: 37.37% one wired provider or none Nebraska: 27.27% one wired provider or none South Carolina: 30.47% one wired provider or none Idaho: 34.87% one wired provider or none Nevada: 23.19% one wired provider or none Vermont: 31.66% one wired provider or none Louisiana: 34.8% one wired provider or none Rhode Island: 20.59% one wired provider or none

Advertised vs measured

06 / The gap, by technology

The map counts a line as broadband on the strength of its advertised tier. But the distance between “up to” and “what arrives” depends almost entirely on the wire. Fiber keeps its promise; long copper and geostationary satellite are where the paper number and the lived experience diverge most.

Illustrative The reach bars encode the documented gap tier for each technology, not a per-provider measurement - the empty stretch is the gap, no fake precise percentage implied. The FCC's Measuring Broadband America program is the real source of measured-vs-advertised throughput. Real The "available at 100/20" figure on each row is the actual BDC December 2025 share.

  1. DSL (copper)

    large gap
    They advertise
    Up to 25 Mbps
    What you actually get
    On long rural copper loops the line syncs well below the “up to” number - frequently an advertised availability the household can never actually reach.
  2. Satellite - geostationary

    large gap
    They advertise
    25 - 100 Mbps
    What you actually get
    The download tier can be met, but a 600 ms+ round-trip and hard monthly caps make it unusable for video calls or gaming. “Available” on paper, marginal in practice.
  3. Fixed wireless

    moderate gap
    They advertise
    Up to 100 Mbps
    What you actually get
    Highly variable - terrain, weather, and distance to the tower decide it. A clear line-of-sight home is fine; a blocked one gets a fraction.
  4. Cable (DOCSIS)

    small gap
    They advertise
    Up to 300 - 1,000 down
    What you actually get
    Download usually lands near the advertised tier off-peak; upload is a small fraction of it, and both dip on congested nodes at night.
  5. Satellite - low-earth-orbit

    small gap
    They advertise
    50 - 200 Mbps
    What you actually get
    Latency drops to 20 - 60 ms and speeds land closer to advertised, but shared capacity means slowdowns where too many subscribe. It reshaped rural options after 2021.
  6. Fiber (FTTP)

    minimal gap
    They advertise
    300 - 1,000 Mbps
    What you actually get
    Delivers at or above the advertised tier, with 5 - 15 ms latency. The gap here is availability, not speed - most homes still can't get it run to the door.

Methodology

07 / What's real, what's illustrative

The coverage, community, and competition figures on this page are real, aggregated directly from the FCC Broadband Data Collection's December 2025 filing - the same data the national map is built from. The honest line still runs down the middle: Real where a number comes from the BDC data, Illustrative where a vignette dramatizes a documented pattern the numbers measure in aggregate.

Source and pipeline

The feed is the FCC Broadband Data Collection (broadbandmap.fcc.gov), pulled through its data-download API with a free FCC account token. Two products drive the page: the location-level availability files - about 116 million broadband-serviceable locations, aggregated from roughly 973 million provider filings across every state and technology - and the Summary by Geography Type file, which the FCC denominates over its full Location Fabric. scripts/build-data.ts folds the two aggregates onto the curated editorial narrative; HANDOFF.md has the exact fetch, token, and aggregation recipe. Speed reality checks would come from the FCC's separate Measuring Broadband America program, which is not wired in.

How the FCC defines “availability” - and why it runs optimistic

A location is counted as served when a provider reports it could supply service there, at its maximum advertised speed, typically within ten business days of a request. Three consequences follow, and they are the spine of this page: “could serve” is treated as “served”; advertised speed stands in for measured speed; and low-orbit satellite, filed at nearly every location, pushes the all-technology number to 99.99% even where no wire reaches. Not a conspiracy - just what the definition literally counts.

What is real

  • The current fixed-broadband benchmark of 100 / 20 Mbps, raised in 2024 from the 25 / 3 Mbps floor set in 2015.
  • Coverage: 99.99% of locations have any 100 / 20 Mbps option, but only 92.76% have a wired one - leaving about 11.8 million locations with no wired option. Unit-weighted over the Location Fabric (162,419,094 locations).
  • Community shares (Urban, Rural, Tribal) and per-technology availability, all from the BDC Summary by Geography Type file, December 2025.
  • Competition: 30.1% of locations have one wired provider or none. Location-weighted from the 116,465,390-location availability files; the state map ranks the same figure.
  • The historical FCC-versus-Microsoft gap: ~21M reported unserved at 25/3 in 2019 against Microsoft's ~120M-plus not actually using broadband speeds.

A note on the two denominators

Coverage and community shares are unit-weighted over the full Location Fabric (the FCC's official denominator, counting each housing unit). The competition figures are location-weighted over the locations that appear in at least one fixed filing - effectively every serviceable location, since satellite is filed nationwide. The two weightings land within about a point of each other on shared measures; each figure uses the denominator that fits its source.

What is illustrative

  • The single-provider vignettes are composites of documented patterns, not named counties with fabricated provider counts. The real single-provider share and the state map above measure the same thing in aggregate.
  • The per-technology advertised-versus-measured delivery bars encode the documented gap tier, not per-provider measurements; the availability figure on each row is real BDC. Measuring Broadband America supplies the real measured numbers.
  • The Compare page is a static example pairing at a hypothetical rural address - a preview of the address-lookup tool, not a live query.

What you're not seeing

Price. Installation quotes that make a “served” address unbuildable in practice. Data caps and throttling. The households the Location Fabric misses entirely. Availability answers “could someone sell you a line here,” which is a narrower question than “can you get affordable, usable internet” - and it is the only question the map is built to answer.
