Is the murder rate the lowest in history
Executive summary
Contemporary analyses find U.S. homicide rates at or near their lowest levels in the era of modern record-keeping, and several recent reports argue murders are at a “100‑year low” or the lowest since the early 1900s [1] [2]; however, long-run historical data and differing measurement methods complicate any absolute claim that today’s rate is the lowest “in history” in every sense [3] [4]. The answer depends on which datasets, years, and geographic scope are compared, and whether 19th‑century—and local or age‑adjusted—rates are included [3] [4] [5].
1. The modern-record consensus: yes, among 20th–21st century measures
National crime-data analysts and criminal-justice groups report that homicide rates declined sharply after the pandemic-era peak and by 2023–2024 reached levels not seen in decades, with some large-city analyses calling the drop the largest single‑year reduction in modern record‑keeping and describing overall violent crime as near a 50‑year low [2] [1] [6]. The Council on Criminal Justice and related reporting attribute the recent pattern to a spike in 2020 followed by substantial declines across many jurisdictions, producing homicide rates that many experts say are the lowest since at least the mid‑20th century [2] [1].
2. Historical benchmarks that challenge a sweeping “lowest ever” statement
Longer historical series show much higher homicide rates in earlier eras: several scholarly reconstructions and historical datasets indicate homicide rates in some places during the 19th century and the early 20th century were substantially higher than today’s levels—examples include county‑level rates in the American West and documented national peaks around the late 20th century, and aggregate historical work warns against directly comparing modern national rates to patchy older records without careful adjustment [4] [5] [7]. Statisticians note the highest modern-era national death rate from homicide was roughly 10.4 per 100,000 in 1980 [3], underscoring that recent lows are relative to 20th‑century highs, not an uncontested floor across all historical periods.
3. Measurement, definitions, and data sources matter
Which source is cited changes the conclusion: FBI UCR, CDC vital statistics, Bureau of Justice Studies reconstructions, and private aggregators (Macrotrends, Statista) each use different inclusion rules, reporting lags, and population denominators, producing slightly different rates for the same years [8] [9] [10] [3]. Analysts caution that comparisons across centuries are especially fraught because older records are incomplete, jurisdictional coverage varied wildly, and definitional changes affect whether a death is counted as homicide [7] [5].
4. What “lowest in history” claims actually mean in public debate
When news outlets and some reports say the murder rate is at a 100‑year low, they typically mean “lowest since roughly 1900 by the measures the report uses,” a defensible but qualified statement grounded in contemporary national databases and major‑city samples [1] [2]. Critics and historians push back that such headlines can obscure important caveats: violent episodes in the 19th century, regional spikes, and measurement differences complicate a blanket historical superlative [4] [5].
5. Bottom line: qualified yes for the modern era, but not an absolute historical first
It is accurate to say U.S. homicide rates have fallen to their lowest levels in many decades and — on the basis of several mainstream modern datasets and city‑level analyses — to levels not seen since the early 20th century [2] [1] [6]. It is not strictly supportable, using the provided sources, to assert an uncontested “lowest in all of history” claim without acknowledging the patchy nature of 19th‑century records, differing methodologies, and geographic variation documented by historians and statistical agencies [4] [3] [7].
