Annual US state broadband-adoption intelligence from the Census Bureau American Community Survey 5-year estimates, table B28002 (keyless official bulk .dat, U.S. public domain): broadband of any type, wired cable/fiber/DSL, dial-up-only, no-internet and no-subscription household shares for the 50 states, the District of Columbia and Puerto Rico over the 2021-2024 vintages, with per-vintage gaps versus the US national share, vintage-over-vintage change, a documented 0-100 digital-readiness score with per-vintage state ranks and i1-i4 tiers, and most/least-connected plus improving/slipping flags. Estimates only (margins of error not carried). Source: U.S. Census Bureau, American Community Survey.

Column	Type	Description
year	integer	ACS 5-year vintage end year (e.g. 2024 = 2020-2024 5-year estimates). Table-based summary files start at the 2021 vintage. (unit: year)
country_code	string	ISO alpha-3 country code (USA for every row). (unit: ISO 3166-1 alpha-3)
state_fips	string	Census FIPS state code (e.g. 06 = California, 11 = District of Columbia, 72 = Puerto Rico).
geo_code	string	Lowercase USPS postal abbreviation of the state/territory (e.g. ca, tx, pr).
geo_name	string	State/territory name.
total_households	integer	Total households, the B28002 universe (B28002_001). (unit: households)
broadband_any_share_pct	float	Households with broadband of any type (B28002_004) as a share of all households. (unit: percent)
wired_broadband_share_pct	float	Households with broadband such as cable, fiber optic or DSL (B28002_007) as a share of all households. (unit: percent)
dialup_only_share_pct	float	Households with dial-up and no other type of internet subscription (B28002_003) as a share of all households. (unit: percent)
no_internet_share_pct	float	Households with no internet access at all (B28002_013) as a share of all households. (unit: percent)
no_subscription_share_pct	float	Households without an internet subscription of any kind (total minus B28002_002) as a share of all households. (unit: percent)
broadband_gap_vs_us_pp	float	Per-vintage gap versus the US national broadband-any share: state share minus US share. Positive = state more connected than the nation. (unit: percentage points)
broadband_chg_pp	float	Vintage-over-vintage change in broadband-any share (percentage points). Null for the 2021 base vintage; never backfilled. (unit: percentage points)
us_broadband_any_share_pct	float	US national broadband-any household share (from the national 0100000US row), broadcast on every row. (unit: percent)
us_wired_broadband_share_pct	float	US national wired-broadband household share, broadcast on every row. (unit: percent)
digital_readiness_score	float	Documented 0-100 digital-readiness score: 100 * (r - 1) / (n - 1) with r the average 1-based rank of the state's broadband-any share (ascending) inside its vintage. (unit: 0-100)
readiness_rank	integer	Per-vintage rank of broadband-any share across the 52 states/territories (1 = most connected; competition ranking, ties share the rank).
readiness_tier	string	Readiness tier from the score: i4_most_connected (>= 75), i3_connected (>= 50), i2_lagging (>= 25), i1_least_connected (< 25).
most_connected_flag	integer	1 when readiness_rank <= 5 (top-5 connected states).
least_connected_flag	integer	1 when readiness_rank >= 48 (bottom-5 connected states).
improving_flag	integer	1 when broadband_chg_pp >= +0.5 (connectivity improving vintage-over-vintage).
slipping_flag	integer	1 when broadband_chg_pp <= -0.5 (connectivity slipping vintage-over-vintage).
row_hash	string	Deterministic 16-hex sha256 over CENSUSBB\|<geo_code>\|<year>; stable across re-ingests of identical data.

First 10 sample rows — a preview, not the complete dataset.
