How do we know this?
Method
Share of nonprofits in this group, counted from the register by registered address, compared with the national share. A difference of at least three percentage points and a ratio of 1.35 or more is needed to show.
Limitations
  • Counts are by registered address, which is often a head office or a trustee, not where the work happens.
  • No population figures are held, so these are shares of organisations, not rates per person.
  • Purpose labels are those given by each national register and are not identical across countries.

What we do not hold here

  • Population, housing, crime, income and other census-style figures: we hold none for the United States here, so nothing above is a rate per person.
  • Nonprofits are placed at the centre of their ZIP code, so distances are to the ZIP centre, not a street address.
  • Congressional districts come from the Census ZIP-to-district file for the 118th Congress; districts redrawn since may differ.
  • State legislators, county and most city councils are not held yet, only governors and statewide officials, two city councils and the US Congress.
  • Private and charter schools beyond the public-school list are not held.
