Organizations the IRS never classified do not appear here. A code is assigned at registration and rarely updated, so it describes what an organization said it would do.

Ohio elsewhere on the Factbook

  • Reported crimeCrime and justice

    Offenses reported to police by type, the trend, and the reporting coverage.

  • Cities by violent crime rateCrime and justice

    What each agency serving 25,000 or more reported, ranked. Agency populations overlap, so these do not add up to the state.

  • Prison populationCrime and justice

    People held under the state’s correctional authority, and the imprisonment rate. A different publisher counting a different thing.

  • Arrests by race, sex and ageCrime and justice

    Arrests as the FBI’s participating agencies reported them, with what the figures can and cannot support at the top.

  • Hate crimeCrime and justice

    Incidents reported to the FBI by bias motivation, as counts — the collection publishes no participation share, so there is no rate to compare states on.

  • Federal obligationsFederal spending

    What federal agencies obligated against a place of performance in the state, per resident and by agency.

  • Payments to doctorsHealth

    What drug and device companies reported paying doctors with a practice address in the state, and the largest recipients.

  • The Ohio Factbook entryAcross the Factbook

    Every measure the Factbook publishes for this state in one place, each with where it ranks among the others and the record it came from.

The immigration hub has no page for a state: CBP publishes by sector and field office, which are its own areas of responsibility rather than a geography, so assigning them to states would be a claim the data does not make. Immigration and the border.

Compared with Illinois.

Full rankings: largest by revenue, largest by assets, and largest grantmakers, and highest reported officer compensation. All organizations: nonprofits.

What this page cannot show

  • The state is the organization’s address of record with the IRS. A national charity registered here operates elsewhere too.
  • Churches need not apply for recognition, so they are under-represented, and the ones here are those that chose to apply.
  • Financial figures exist only for organizations with a Form 990 on record, and each describes whichever year that organization last reported.

Full method at methodology.
