Connecticut elsewhere on the Factbook

  • Reported crime Crime and justice

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

  • Cities by violent crime rate in Connecticut Crime 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 population Crime 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 age Crime and justice

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

  • Hate crime Crime 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 obligations Federal spending

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

  • Registered nonprofits Nonprofits

    How many organizations the IRS lists in the state, what they report as revenue, and which kinds of work they do.

  • Payments to doctors Health

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

  • Immigration courts Immigration 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 payments Farm 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 loans PPP 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.

  • Population, age, income and origin Demographics

    The Census Bureau's population estimates year by year, with births, deaths and migration, and age, income, poverty, housing and origin from the American Community Survey, each with its margin of error.

  • Public schools Schools

    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.

  • Banks and credit unions Banks and credit unions

    The FDIC-insured banks headquartered in the state and their offices, and the credit unions based there and their sites, each per resident and against every other state.

  • Housing Housing

    The homes under HUD’s rental assistance programs in the state, by program and county, and its tax-credit housing, each per resident and against every other state.

  • Mortgage lending Mortgage lending

    The mortgage applications, loans and denials lenders reported in the state under the Home Mortgage Disclosure Act, and its largest lenders and counties.

  • Cost of living Cost of living

    BEA’s price level for the state against the nation, for goods, rents, utilities and other services, and its metro areas beside it.

  • Treatment facilities Treatment facilities

    Substance use and mental health treatment listings in the state, as SAMHSA’s directories print them: not a license, a rating or a recommendation.

  • Health centers Health centers

    Community health center sites in the state, from HRSA’s Data Warehouse, by county and by the organization that runs them: no rating and no recommendation.

  • Pandemic relief Pandemic relief

    COVID-19 relief obligated to the state’s government, from PRAC’s state workbook, by awarding agency: not every award made in the state, and no PPP loan.

  • County health County health

    CDC’s model-based estimates of adult health, risk behaviors and prevention for every county in the state, each with its 95% interval.

  • Historic places Historic places

    Every place on the National Register of Historic Places in the state, by county and by the year it was listed, from the National Park Service’s listed-properties file.

  • Health care exclusions Health care program exclusions

    Every exclusion in effect in the state on OIG’s list of people and organizations barred from Medicare, Medicaid and every other federal health care program, by authority and year.

  • Registered aircraft Aircraft registry

    Aircraft on the FAA’s register whose registrant’s address is in the state, and the kind of registrant that holds them.

  • H-1B salaries H-1B salaries

    The offered wages on H-1B applications the Department of Labor certified with a first worksite in the state, by occupation, each median with the count behind it.

  • Disaster declarations Disasters

    Every federal disaster declaration FEMA made for the state, by type, incident and county, with each measure’s rank among the states and territories.

  • College athletics Sports

    Every college in the state that reported to the Equity in Athletics survey, ranked by its athletics revenue, with its expenses, athletes and athletic aid.

  • Federal civilian workforce Federal salaries

    Federal civilian employees stationed in the state by agency and occupation, with the pay OPM publishes and the share it withholds.

  • State payroll State payrolls

    The state government's own payroll: what it paid each year, by agency, from the state's file.

  • The Connecticut Factbook entry Across 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.
