Twelve plates from the atlas
The atlas, in four parts
Reference-grade and beautifully made — total coverage, the long election record, atlas-grade maps, and a named source behind every figure.
A page for every place
Thirteen levels of geography — nation, region, state, county, metro, media market, district, city — pre-built for tens of thousands of places, with the rest of the census long tail served on demand.
Every election since 1876
County-level presidential returns across 148 years, compiled from the MIT Election Lab, ICPSR, and certified state results — with precinct- and block-level detail in the modern era.
Maps drawn like plates
A nationwide explorer, precinct-level detail, and a time machine across 38 elections — crisp boundaries, restrained color, legends that say exactly what the map encodes.
Every figure carries its source
Named federal and academic origins on every number, open JSON behind every page under CC BY 4.0, and markup built to be cited — by readers, by newsrooms, and by machines.
Tools
Beyond the pages: explore the national map, compare two places, draw your own region, or ask the data a question directly.
Map explorer
The whole country as one instrument — every county colored by margin, any election year, any thematic layer.
Compare
Set any two places side by side — 2024 margins, the long arc since 1876, demographics, and how they diverged.
Canvas
Draw any region on the map and Akashic computes its rollup — constituent counties, presidential margins, and demographics.
Ask
Ask a question in plain English and get an answer grounded in the Akashic corpus, with citations back to the source pages.
Atlas+ · premium narrative profiles
The narrative edition of the atlas.
Atlas+ layers a full-length, fully sourced profile onto a place page — how the place came to vote the way it does, who lives there now, what it makes, and what to watch next — over the same tables and maps the atlas already keeps.
