Texas 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 Texas 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.

  • 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.

    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.

    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.

    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.

  • 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.

  • Child care prices Childcare costs

    What child care centers and family child care homes charged in each county of the state, as DOL’s National Database of Childcare Prices publishes them, with the counties it leaves blank.

  • Economy Economy

    The state’s counties on BEA’s county GDP and personal income tables: real GDP, personal income and per-capita personal income, with the counties BEA withholds a figure for.

  • 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

  • Disaster declarations Disasters

  • 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.

  • The Texas 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.
