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

  • Most dangerous cities in IdahoCrime 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.
