Connecticut elsewhere on the Factbook

  • Reported crimeCrime and justice

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

  • Most dangerous cities in ConnecticutCrime 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.

  • Immigration courtsImmigration and the border

    The EOIR courts sitting in the state, what they completed and still have pending, and how far apart their asylum grant rates are. The courts, not the state’s residents: a detention court hears cases from far outside it.

  • 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 Connecticut 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 link above is EOIR’s courts, which sit in this state. CBP’s encounters are not by state and will not be: its sectors and field offices are areas of responsibility rather than a geography, and assigning them to states would be a claim the data does not make. Immigration and the border.
