Republican politicians and sympathetic media outlets are claiming that America is in the midst of a violent "crime wave," driven in part by undocumented immigrants. New data, however, demonstrates that there was not a spike in violent crime in 2023. Instead, across America, rates of violent crime are dropping precipitously — and the decline is especially pronounced in border states. 

In January 2024, the Republican National Committee claimed that “crime continues at historic highs in Democrat-run cities.” Representative Jim Jordan (R-OH) declared in February 2024 that “[i]n Joe Biden’s America you get…cities plagued with crime.” These claims, however, are not supported by facts. 

The most comprehensive look at violent crime in the United States in 2023 will come when the FBI publishes its national Uniform Crime Report. But that will not happen until the fall. But, as crime analyst Jeff Asher explains in his newsletter, the FBI report is based on individual Uniform Crime Reports submitted by each state. Asher identified 14 states that have released their Uniform Crime Reports publicly. The data has not been completely finalized and could be adjusted slightly before formally submitting it to the FBI. But this data is the best early look at violent crime trends last year. 

Asher found that both murder and violent crime declined in 12 of 14 states. 

The only states that saw murders increase or stay flat, Rhode Island and Wyoming, had a very small number of total murders relative to other states — 28 and 14, respectively. This confirms previously available data from major cities in 2023 that showed sharp declines in murder and a smaller, but still significant, decline in violent crime. St. Louis and Baltimore saw their lowest murder rates in about a decade. Detroit was on pace for its lowest murder rate since 1966. 

Republicans and aligned media outlets claim that undocumented immigrants are driving the purported increase in crime. In a recent speech at the border, Former President Donald Trump falsely claimed that the “United States is being overrun by the Biden migrant crime.” Trump has made the issue a central focus of his campaign. 

Other politicians are following Trump's lead. On a March 3rd appearance on Fox News, Senator Marco Rubio (R-FL) said that “[w]e face a growing migrant crime wave because Biden has released into America tens of thousands of illegal migrants who were criminals in their own country.” In Arizona, Kari Lake – a Trump ally who is currently running for Senate – claimed Biden was allowing “literal foreign armies” to cross the border. The House GOP also issued a press release this month with the headline: “Joe Biden’s Open Borders Have Unleashed A Catastrophic Crime Wave Across The Country.”

On Fox News, “migrant crime” has emerged as a coverage staple in less than two months. Host Jesse Watters told viewers in late February that “[t]here is a migrant crime spree killing Americans.” According to the Washington Post, “Fox News hosts, guests and video clips have mentioned ‘migrant crime’ nearly 90 times” in the month of February.

Notably, the two border states that have completed their Uniform Crime Reports saw particularly sharp declines in murder in 2023, with 15% drop in Texas and 8.8% drop in Arizona. Both states also saw significant declines in violent crime overall. If undocumented immigrants were driving a violent crime surge, as Republicans and some media outlets suggest, you would expect to see it show up in the data from Texas and Arizona. 

Every act of violent crime is significant, and the modern media environment allows news of individual offenses — like the alleged murder of Laken Riley by an undocumented immigrant — to travel widely. But Asher told Popular Information that "discussion of an increasing violent crime trend driven by migrants is lacking in any factual basis." He noted that "violent crime rates in Texas border counties have remained relatively low and below both the rest of Texas and the US as a whole" over the last decade. That is not the kind of data one would expect to see "if a surge in violent crime was being driven by migrants." Therefore, Asher said, "any hypothesized increases in crime committed by migrants is either too small to show up in reported crime data or the hypothesized increases are not occurring."

Republicans, including the National Republican Campaign Committee (NRCC), are also claiming that "noncitizen crime including, homicide, burglary, battery, and sexual offenses has risen 514.7% since Biden took office." This is false. 

The data linked to by the NRCC tracks people who are arrested at the border by U.S. Customs and Border Protection (CBP) that have a prior criminal record in any country. It has nothing to do with new crimes that occurred in the United States. The most common prior convictions for people arrested at the border are illegal crossing and other immigration offenses. As Aaron Reichlin-Melnick, an expert at the American Immigration Council, notes, the CBP arrested over 2 million people at the border in Fiscal Year 2023, which covers October 1, 2022 to September 30, 2023. Of those arrestees, just 6,477 (0.3%) had a prior criminal conviction unrelated to their immigration status. 

Researchers who studied the issue have found that undocumented immigrants are less likely to commit crimes than American citizens. From 2012 to 2022, undocumented immigrants were 14% less likely to be convicted of murder and 41% less likely to be convicted of any criminal offense. Similar research by Michael Light at the University of Wisconsin found lower rates of "homicides, sexual assaults, violent crimes, property crimes, traffic and drug violations" among undocumented immigrants.
