Release boundaries and measurement rules

The atlas stays visually richer without hiding what is measured, what is modeled, or what is still held out of indexing.

ACS 2024 footprint

Footprint measures come from ACS 2024 ancestry fields and stay separate from modeled politics.

Modeled geography, not individual behavior

Political pattern notes describe modeled geographic concentration across 2000-2024 presidential results.

Release discipline

Indexed and experimental dossiers stay explicitly labeled throughout the atlas.

Atlas map stage

Live map stage

This stage keeps the atlas product-led: switch the subject, change the geography frame, and read the leaderboard without dropping into the lower full catalog yet.
