Local data

Local data, tied to named sources

These pages take a public dataset, show the figure for one place, and connect it to a calculator so you can run your own numbers. Every value lists its source and the period it covers.

How these pages stay trustworthy

  • Each figure maps to a named public dataset with a link and the period it covers.
  • Pages whose source data passes its freshness window stay indexed; stale entries drop out automatically until they are re-verified.
  • Every page links to the matching calculator so the number is a starting point, not the end.
