Delaware elsewhere on the Factbook
- Reported crimeCrime and justice
Offenses reported to police by type, the trend, and the reporting coverage.
- Most dangerous cities in DelawareCrime 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.
- Registered nonprofitsNonprofits
How many organizations the IRS lists in the state, what they report as revenue, and which kinds of work they do.
- 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.
- Paycheck Protection Program loansPPP loans
The PPP loans SBA guaranteed to businesses operating in the state, by county, with how many carry a forgiveness amount and how many were charged off. Loans, not businesses: a business with two draws is two loans.
- Public schoolsSchools
Pupils, schools and teachers, the largest districts, what districts spend per pupil and where the money comes from, and the colleges that take federal student aid.
- Federal civilian workforceFederal salaries
Federal civilian employees stationed in the state by agency and occupation, with the pay OPM publishes and the share it withholds.
- The Delaware 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.
