A 148-year picture of every American county.

Data sources

Presidential election results, 1876–2024

Compiled from the MIT Election Lab county-level series and the ICPSR historical archive, with precinct-level totals from VEST aggregated to the modern county boundaries. For example: ICPSR carries the 1896 Bryan-McKinley returns at the county level; MIT EL is canonical from 1916 forward; the 2024 totals come from each state’s certified returns rather than newswire.

Demographics

US Census Bureau American Community Survey 2024 5-year estimates (2020–2024 reference period). Connecticut data uses the post-2022 Planning Region geography; pre-2022 county-level election totals are apportioned to planning regions by 2020 town-level population. For example: the “Median household income” figure on every county page is the ACS 5-year estimate, inflation-adjusted to 2024 dollars; suppressed small-population estimates render as —, never as zero.

Religious adherence

2020 US Religion Census published by the Association of Statisticians of American Religious Bodies (ASARB). ASARB reports adherent counts for roughly 250 religious bodies per county; Akashic buckets them into seven traditions: Baptist, Methodist, Pentecostal & Holiness, Catholic & Orthodox, Mainline Protestant, Other Christian, Non-Christian. For example: in Utah counties the “Other Christian” tradition is dominated by LDS adherents; in the Texas Rio Grande Valley the “Catholic & Orthodox” share regularly exceeds 60%.

Geographic boundaries

US Census TIGER/Line 2024 county and precinct shapefiles, simplified for web rendering. Precinct maps display the 2024 boundaries. For example: the precinct map on a Harris County, TX page renders 1,074 voting precincts as drawn for the November 2024 election; counties without precinct geometry on file fall back to a hex-grid layout that preserves the aggregate county margin.

County hero photography

Curated from Wikipedia and Wikimedia Commons under public-domain and Creative Commons licenses (CC BY, CC BY-SA, CC BY-ND). Each image links to its source with full attribution. For example: the hero on the McDowell County, WV page is a 1946 Library of Congress photograph of a UMW union hall; the hero on Cook County, IL is a CC BY-SA skyline of the Chicago Loop.

Editorial copy

County subheads and the lead paragraph of each narrative are editor-curated. Subsequent paragraphs are deterministically generated from the underlying election and demographic data. For example: the subhead on the McDowell County page is editorial copy; the paragraph that follows it summarizing the post-2000 margin trajectory is generated from the election table.

Methodology notes

• Pre-1928 data is sparse. About 60% of county-year combinations before 1928 have no recorded result. We render those as gaps in the table rather than interpolating.
• Boundary changes. A small number of counties have changed names or boundaries (Miami-Dade renamed from Dade in 1997; Connecticut’s 2022 planning-region switchover). We carry forward the modern FIPS code.
• Similar counties are computed by cosine similarity of the last-ten-election margin vector. The result reflects political similarity, not demographic or geographic similarity.
• Precinct maps show 2024 boundaries, with vote totals disaggregated to the precinct level. Counties without precinct geometry on file fall back to a hex-grid layout that preserves the aggregate county margin.
• What’s not here. Ballot measures, downballot races, primary results, and turnout demographics are not included on these pages. They live in the broader Akashic platform.

Coverage

One page for every place the federal government tracks at a politically meaningful scale. Pre-built and statically served: 3,143 counties, 51 states, 918 metro areas, 180 combined metros, 208 media markets, 435 congressional districts, roughly 6,800 state legislative districts, and 6,687 cities and towns of 5,000 or more residents. The remaining long tail of ~25,000 smaller places is served on demand. Type any US address or place name on the homepage and you land on the page for the place that contains it.

Counties — 3,143

Every county the Census Bureau recognizes, from Kalawao County, HI (population 82) to Los Angeles County, CA (population 9.7 million). All 50 states plus DC plus the 9 Connecticut planning regions (the post-2022 successor to Connecticut’s county system). Hosted on akashic.app/county/{FIPS}.

States — 51

Every state plus DC. Population-weighted roll-ups from the constituent counties, with the same 148-year election table and demographic profile applied at the state scale. Hosted on akashic.app/state/{ABBR}.

Congressional districts — 435 (120th Congress)

Every US House district on the lines in force for the 2026 election, including the Texas and California mid-decade redraws. Presidential results are block-aggregated — precinct returns disaggregated to census blocks and re-summed inside each district — so districts that cross county lines (TX-22, IL-7, and most urban districts) get exact totals rather than county-share estimates. The District of Columbia’s at-large delegate seat gets a page as well — not counted among the 435, but roughly a district’s worth of people. Hosted on akashic.app/cd/{ID}.

State legislative districts — ~6,600 (about half of total)

State senate (sld-upper) and state house (sld-lower) districts where a county crosswalk exists. That covers most of the country’s 7,386 state house seats and 1,973 state senate seats — the remainder are pending source-data acquisition for states whose district lines do not nest cleanly into counties.

Metro areas (CBSA) — 918 and media markets (DMA) — 208

Every Census-defined Core Based Statistical Area (CBSA) and every Nielsen Designated Market Area (DMA) — from the New York DMA (21 million people) to the Glendive, MT DMA (4,600). Allocation-weighted from constituent counties. Hosted on akashic.app.

Cities & towns — 6,687 (places of 5,000+ residents)

Every incorporated place and Census Designated Place with at least 5,000 residents gets a full static profile at akashic.app/city/{FIPS}. Presidential results are block-disaggregated from precinct returns — a city core is measured separately from its surrounding county — and cover the modern era (2008–2024). Demographics blend authoritative block-level scalars with county-allocated detail panels.

Custom polygons

Draw any shape on the Canvas tool, sign in, and Akashic rolls up presidential history for every county your polygon intersects — useful for a media buy, a school district, a congressional redistricting proposal, or any geography the federal government does not track on its own. Each saved shape gets a permanent shareable URL.

Long-tail places

The remaining ~25,000 incorporated places and Census Designated Places under 5,000 residents — every town, every village, every CDP large enough for the Census to list. Served on demand from the Neon Postgres backing store at akashic.app/place/{geo_id}, with the same 2008–2024 block-disaggregated results, a key-facts panel, and links to the containing county and state. Places promoted to the static city tier redirect there automatically.
