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.

Method

Method and release rules

The redesigned atlas remains evidence-first: richer color and stronger structure, but the same release rules and contract boundaries.
Source basis
Source basis
ACS 2024 footprint data anchors the atlas. Strongest geographies and Explorer layers reflect share of total population, not normalized sub-populations.
Publishing boundary
Publishing boundary
Experimental dossiers remain atlas-visible but noindex until they graduate into the narrower public benchmark release.
Explorer handoff
Explorer handoff
The atlas is browse-first, but every spotlight and map state hands off cleanly to the place Explorer for county and state context.
