Trust and evidence scope
Release status, source chain, and modeling boundaries
Every dossier declares what is published, where the data comes from, and where modeled geography stops short of observed individual behavior.
Release status
ELIGIBLE
Search-indexed public release in the current dossier set.
Political basis
Latest 2024
Latest modeled series: 2024 R+12.2, high.
Source chain
- Footprint source: ACS 2024 ancestry fields from demographics_ancestry.
- Politics source window: presidential model output spanning 2000 through 2024 from the latest completed ancestry_vote_estimates run.
- Release policy: public-release dossiers are indexed; experimental dossiers remain labeled and excluded from search indexing.
- Interpretation: modeled political geography, not observed individual vote behavior.

- County candidates come from the top 250 counties ranked by footprint share inside this dossier.
- Actual context is the 2024 presidential margin for each county, computed as (Dem - Rep) / total votes * 100.
- Modeled baseline is the latest published ancestry-model national Democratic margin for this group.
- Residual = county actual margin minus the modeled baseline; rows rank by absolute residual with footprint share as the tiebreaker.
- This module describes modeled geography versus county election results, not individual behavior.

Methodology and exports
Public notes on source tables, measurement scope, modeling boundaries, and exportability.
- Ancestry footprint metrics use ACS 2024 source columns mapped from the canonical ancestry taxonomy.
- Public geography tables rank states and counties by share of total population reporting the ancestry.
- State and national ancestry shares are weighted from county populations whenever a direct aggregate row is unavailable.
- Political timelines use the latest completed ancestry model run and surface model version plus confidence labels directly.
- Indexed public-release dossiers remain search-visible; experimental dossiers stay public in the atlas but noindex until promoted.
- These pages describe modeled voting patterns, not direct measures of individual behavior.
