Primes¶
- Modifiable Areal Unit Problem
- The identical skeleton appears in a macroeconomist computing volatility under quarterly versus annual aggregation, a commission drawing alternative district maps from identical voter data, a network scientist running community detection at different resolutions, a histogram displaying the same data as unimodal or bimodal under different bins, and a climate scientist computing trends at different grid scales.
This sourceDemonstrates empirically that correlations computed on aggregated areal data range across nearly the whole interval depending on how units are drawn (scale and zoning effects).

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
