Did Police Funding Cuts Cause the 2020 Crime Surge?
Firearm homicides rose 31% in 2020 and peaked in 2021. The narrative that "defund the police" caused this is widespread. The data tells a more complicated story — one involving a pandemic, a historic gun-buying surge, and genuine uncertainty about cause and effect.
The 2020 Homicide Spike: What the Data Actually Shows
The 2020 homicide increase is one of the most thoroughly confirmed events in modern crime statistics. It shows up in two independent measurement systems that share no common data pipeline: police-recorded homicide counts (FBI UCR) and death-certificate mortality data (CDC/NCHS). When two separate systems using different methods agree, the signal is real.

02 – The Trend in ContextThe spike was severe — but it must be put in historical context. Firearm homicide peaked nationally in the early 1990s, fell dramatically through the 2000s and early 2010s, rose modestly through 2019, then spiked sharply in 2020–2021. Even at the 2021 peak (6.7/100k), the rate was below the early-1990s highs. The narrative of an "unprecedented" crime wave is accurate only for the speed of the increase, not its absolute level.

The FBI transitioned from the legacy Summary Reporting System (SRS/UCR) to the National Incident-Based Reporting System (NIBRS) during 2021. This creates comparability problems for the 2021 data point specifically. The CDC mortality series — which is independent — does not share this limitation. For the 2020 spike in particular, both systems agree, lending high confidence to that year's increase.
The "Defund the Police" Hypothesis: What the Evidence Shows
The defund hypothesis requires that budgets actually were cut. A peer-reviewed study published in Social Problems examined police budget changes across 264 U.S. cities in the period surrounding the 2020 protests. The finding is unambiguous: there is no evidence that 2020 protest exposure reduced police budgets. In some contexts, police budgets actually increased in cities that experienced the most protest activity.
This is not a minor caveat — it removes the primary mechanism for the "defund caused crime" claim at the national level. If budgets weren't broadly cut, budget cuts cannot explain a national trend.
| City | Claimed Action | Actual Budget Change | Sworn Officers Change |
|---|---|---|---|
| Minneapolis, MN | Pledged to "dismantle" MPD | City council vote failed; operating budget largely intact | Staffing declined via attrition, not formal cuts |
| Los Angeles, CA | $150M redirect announced | LAPD budget later restored/increased in subsequent cycles | Modest short-term reduction |
| New York City, NY | $1B NYPD "cut" announced | Largely achieved via accounting reclassifications, not real reductions | Attrition accelerated; retirements spiked |
| Austin, TX | $150M redirect | Some reductions real; subsequent years saw re-funding under state law | Staffing did decline; reversed by 2022–23 |
| National average (264 cities) | N/A | No systematic budget reduction detected | Attrition stress widespread; formal cuts rare (<10% of departments) |
Even where formal budget cuts were absent, police departments faced real staffing pressure after 2020 through accelerated retirements, resignations, and reduced recruiting pipelines. In 2020, the FBI reported 696,644 sworn officers nationally across reporting agencies — a figure that masked significant vacancy rates in many large departments.
However, attributing the homicide spike to staffing attrition faces a key problem: the attrition was gradual and ongoing, while the homicide spike was sharp and sudden (occurring within 2020 itself, before most attrition effects would have fully materialized).
• Evidence that cities with the largest budget/staffing cuts experienced proportionally larger homicide increases — consistent with a dose-response relationship. (Not observed in 264-city budget study.)
• A causal mechanism: a study showing that specific enforcement reductions preceded homicide increases in the same jurisdictions, with strong pre-trend evidence. (The best available design finds the opposite.)
• Cross-national evidence: countries that cut policing saw crime surges while those that didn't were spared. (The 2020 surge was largely U.S.-specific, while peer nations also saw some COVID-era homicide increases without defunding.)
De-Policing: Did Enforcement Pull Back — and Did It Matter?
"De-policing" is distinct from budget cuts: it refers to reduced proactive enforcement — fewer traffic stops, pedestrian stops, officer-initiated contacts, and arrests for low-level offenses. This is measurable, and it did happen.
A peer-reviewed study published in Perspectives on Politics used a regression discontinuity-in-time (RDiT) design to measure what happened to policing and crime in four cities (Austin, Los Angeles, Philadelphia, and Seattle) immediately after the onset of 2020 protests. Key findings:

Competing Causes: What Else Drove the 2020 Surge?
One of the clearest correlates of the 2020 homicide spike is a historic surge in firearm purchases. NICS background check applications jumped from approximately 14 million in 2019 to over 25 million in 2020 — a near-doubling in a single year. Applications remained elevated at 22.4 million in 2021.
The CDC data provides critical evidence here: the 2020–2021 surge was almost entirely a firearm homicide increase. Non-firearm homicide did not rise proportionally. This pattern — where the firearm-specific harm increases while non-firearm harm does not — is exactly what a weapon availability hypothesis would predict.

08 – Pandemic-Era Social DisruptionThe 2020 crime surge coincided with the most severe social disruption the United States had experienced in decades. Schools closed. Courts halted proceedings. Social services were interrupted. Economic stress peaked suddenly. Routine activities that structure social life — work, school, community organizations — were suspended or radically altered.
Criminology research has long linked disruptions to routine activities and social controls with increases in violence. The 2020 spike was also preceded by massive civil unrest — not just protests, but fires, curfews, and the social and psychological aftermath of George Floyd's killing in late May 2020. The homicide increase appears in data starting in June 2020, coinciding with the protests and their aftermath rather than with any specific budget vote.
If police budget cuts caused the crime spike, the spike should follow the cuts. But formal budget cuts — where they occurred at all — happened in city council votes in summer and fall 2020. The homicide increase began immediately in late May/June 2020, before most budget processes concluded. The timing is more consistent with the simultaneous protests and social disruption as precipitating factors than with formal budget changes.
| Proposed Cause | Evidence Strength | Key Support | Key Problem |
|---|---|---|---|
| Police budget defunding | Not supported | Intuitive mechanism | 264-city study: no systematic cuts occurred |
| De-policing / enforcement pullback | Weak–Moderate (localized) | RDiT shows enforcement did decline | Same RDiT finds no resulting crime increase |
| Firearm acquisition surge | Moderate | Firearm-specific homicide increase; NICS surge | NICS is imperfect proxy; causal channel uncertain |
| Pandemic social disruption | Moderate–Strong | National increase coincides with protests/disruption; broad-based | Hard to separate from simultaneous factors |
| Measurement artifact | Not supported for homicide | NIBRS transition is a real issue for 2021 | FBI and CDC both show 2020 increase; independent systems |
Steelman: The Best Case for Both Sides
The strongest version of this argument focuses not on formal budget cuts but on the legitimacy crisis and behavioral withdrawal that followed the Floyd killing and protests. The argument runs: even without formal defunding, officers dramatically reduced proactive activity — the data confirms this. Reduced deterrence and reduced clearance rates would be expected to increase violence. The Ferguson Effect (reduced policing following high-profile use-of-force controversies) has some supporting evidence from earlier years. The timing of the June 2020 onset is consistent with a behavioral change, not just a budget change.
The strongest version of this argument is that the pandemic, not policing, was the dominant driver. COVID-19 disrupted every institution simultaneously: courts stopped processing cases, social services shut down, schools closed, and millions of people lost jobs overnight. Gun purchases nearly doubled. These shocks overwhelmed normal social controls with no connection to police behavior. The same period saw homicide increases in countries that had no "defund" movement. The rapid decline after 2021, while policing controversies continued, suggests the pandemic-era shocks were temporary rather than policing-related.
The Data Verdict
On the strongest causal and mechanism evidence available, policing changes after 2020 are not supported as the dominant national cause of the 2020–2021 violence surge. "Defund the police" as a national budget-cutting program largely did not happen. De-policing did occur, but the best quasi-experimental evidence finds no clear resulting increase in violent crime in treated cities.
The cross-system evidence most strongly supports a multi-factor pandemic-era explanation with increased firearm availability as a central component. This does not mean policing is irrelevant to crime — decades of research show it matters. It means the specific "defund caused crime" causal chain is not supported by the available evidence for the 2020–2021 national surge.
• A multi-city pre-registered DiD/event-study linking exogenous variation in policing to subsequent homicide increases — validated with mechanism shifts and strong pre-trends — would upgrade the de-policing hypothesis.
• City-level clearance and response-time panels showing that clearance fell sharply before homicide increases — with credible identification — would strengthen the policing-centric narrative.
• Better quasi-experimental designs connecting specific firearm acquisition changes to firearm homicide — beyond NICS proxies — would sharpen the weapon-availability hypothesis.
