Falling crime and the underreporting alibi

Every time police-recorded crime falls, someone says the drop is just people not reporting it. It is a serious objection, and it is testable.

Police numbers are an indirect measure. A murder gets recorded because there is a body. A robbery gets recorded only if someone calls. So if the public stopped calling, a falling police series could be an artifact of reporting rather than a real change. That is the alibi. The test is whether an independent measure of victimization fell by the same amount.

The independent measure

The BJS National Crime Victimization Survey asks a sample of households directly whether they were victimized, whether or not police were told. I pulled the public microdata (1993-2024) and weighted it myself. Violent victimizations per 1,000 people age 12 and up:

  • 1993: 79.8
  • 1994: 80.0 (the peak)
  • 2020: 16.4 (the low)
  • 2022: 23.5
  • 2024: 23.3

Down 70.8% from 1993. If that fall were an artifact of which offenses get counted, removing the softest category should kill it. Strip out simple assault and keep only rape, robbery and aggravated assault: still down 69.4%.

The police series agrees where it matters most. Murder and nonnegligent manslaughter per 100,000: 9.8 in 1991, 5.0 in 2019, 4.1 in 2025. The 2025 figure ties 1955-56 for the lowest in the FBI's 90-year estimate series. Murder is the offense least sensitive to reporting behavior, so it is the right second check.

Where the alibi half-works

Reporting rates are not constant, and the two measures do not move in lockstep. From 2023 to 2024 the victimization rate rose, 22.5 to 23.3, while the FBI reported violent crime down 4.5%. Some offense types are genuinely climbing; NYPD felony assault has risen six years running. Anyone who tells you the two series agree year by year is overfitting.

The long-run claim is the one that survives. For underreporting to drive a 70% fall over three decades, the reporting rate in 1993 would have to have been roughly three times what it is now, and the victim survey would have had to go flat. It did not go flat. It fell almost exactly as far as the police series did.

What the fear got right

2020 to 2022 was a real spike. Victimization rose 43% off the 2020 low. If you formed your view of crime during that window, you were not imagining it. But "out of control" does not fit 2023-2026, and the public has partly updated: Gallup's share saying crime is rising fell from 77% to 49%.

What I will not hide

US homicide is still roughly four times Western Europe's. Police data had real gaps after the 2021 NIBRS transition, and the FBI now reports 96% population coverage, not 100%. The victim survey has its own limits: it does not capture homicide, crimes against businesses, or people outside households, and it was redesigned in 2006. Sampling error on a single year is wide enough that year-over-year moves are mostly noise.

Verdict

The multi-decade fall is real and it is not a reporting artifact. And "crime is fine" still does not follow from it.

Both halves matter. The alibi is dead as an explanation of the trend. It is alive as a caution about the last two years.
