South Dakota 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.
- Farm program paymentsFarm subsidies
What the Farm Service Agency paid through the state’s county offices, by program and by recipient. The offices that administered the payments, not a count of farms: a recipient addressed elsewhere is counted where they were paid.
- The South Dakota 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 this state: EOIR runs no immigration court here, and CBP publishes by sector and field office, which are its own areas of responsibility rather than a geography. Immigration and the border.
Compared with North Dakota.
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.
