Significance

Despite that centrality come public and political discourse, we absence even simple information on an essential questions concerning undocumented immigrants and crime. This stems mostly from data constraints. Going beyond existing research, we use data native the Texas department of public Safety, which checks and also records the immigration status of every arrestees throughout the state. Contrary to publicly perception, us observe significantly lower felony arrest rates amongst undocumented immigrants compared to legal immigrants and also native-born us citizens and also find no evidence that undocumented criminality has actually increased in current years. Ours findings assist us understand why the most aggressive immigrant removed programs have actually not yielded on your crime palliation promises and also are i can not qualify to execute so in the future.

Abstract

We make use of uniquely considerable arrest data from the Texas room of Public safety and security to to compare the criminality the undocumented immigrants to legitimate immigrants and also native-born united state citizens in between 2012 and also 2018. We find that undocumented immigrants have substantially lower crime prices than native-born citizens and also legal immigrants across a range of felony offenses. Loved one to undocumented immigrants, US-born citizens are over 2 times much more likely to be arrested because that violent crimes, 2.5 times an ext likely to it is in arrested for drug crimes, and also over 4 times much more likely to it is in arrested for residential property crimes. In addition, the relationship of arrests including undocumented immigrant in Texas was relatively stable or decreasing end this period. The differences in between US-born citizens and also undocumented immigrant are robust to using alternate estimates that the more comprehensive undocumented population, alternating classifications of those counted as “undocumented” in ~ arrest and substituting misdemeanors or convictions as procedures of crime.


The tripling the the undocumented population in recent years is among the many consequential and also controversial social patterns in the United claims (1). Backlash regarding the criminality the undocumented immigrants is in ~ the fore that this controversy and has caused immigration reforms and also public policies intended to minimize the crimes associated with undocumented immigration (2). As freshly as June the 2020, the debate on undocumented criminality do its method to the united state Supreme Court, wherein the united state solicitor basic sought to invalid California’s “sanctuary” policies since “hen police officers are unable to arrest aliens—often criminal aliens—who space in removal proceedings or have been ordered gotten rid of from the joined States, those aliens rather return come the community, whereby criminal aliens are disproportionately most likely to walk crimes” (3, p. 13).

Indeed, pertains to over illegal immigration have actually arguably to be the government’s chief criminal legislation enforcement priority for years, come the point where the federal government now spends an ext on immigration enforcement 보다 all other principle criminal law enforcement agencies linked (4, 5). This policies, practices, and also pronouncements, however, have much outpaced ours empirical expertise of undocumented criminality. That is, while research says that immigrants typically tend to be less crime vulnerable than their aboriginal peers (6), us still lack basic information on basic questions certain to undocumented immigrants and also crime. Exactly how does the criminality that undocumented immigrants to compare to legal immigrants or native-born citizens? walk this differ by the form offense, such as property, violent, or drug crimes? and how has undocumented immigrant criminality readjusted over time?

Each of these concerns represents exceptional gaps in our scientific and also policy understanding of undocumented immigration. This dearth is largely due to data limitations. Calculating group-specific crime rates is straightforward: the is the number of arrests within a particular group split by its populace (expressed every 100,000). In the situation of undocumented immigrants, however, because that years us lacked reliable estimates for both the numerator and also the denominator forced for such calculations. About the number of undocumented immigrants (the denominator), data quality has improved in current years as the facility for migrate Studies and the Pew Research facility now produce annual state- and national-level approximates of the undocumented population, ranging from 10.5 come 10.7 million in 2017 (1, 7).* Data top top undocumented criminality (the numerator), however, have actually acquired worse end time. Regardless of the boosting centrality of local police in immigration enforcement (9), details on immigration status is substantial scarce in most crime databases. Among the many widely made use of crime data sources, neither the Uniform Crime Reports, the nationwide Crime Victimization Survey, nor the nationwide Incident-Based Reporting system record information around immigration status. In addition, California stopped reporting the variety of noncitizens in their custody come the bureau of justice Statistics (BJS) in 2013 and in 2017 came to be a “sanctuary state” by limiting info sharing between local criminal justice officials and also federal immigrant authorities (10). In 2016, they in addition to Nevada, new Hampshire, phibìc Dakota, and also Oregon did not report info on citizenship in your prison populations, and the BJS speculates that other states “likely provided undercounts” (11, p. 13).

This article is a notable exception to this tendency in that, after testimonial for scientific merit, the Texas room of Public safety (DPS) granted our research study team accessibility to instance processing info for all arrests recorded in between 2012 and also 2018. The DPS data are distinctive in that they totally cooperate through the department of Homeland protection (DHS) to check and record the immigration standing of every arrestees transparent the state, including their legal condition (21). Making use of these data, we attend to the empirical shortcomings that have actually hampered prior work in this area through accomplishing 3 interrelated objectives.

First, we market a detailed contemporary assessment that the comparative criminality in between native-born us citizens, legit immigrants, and undocumented immigrants. The limited information we carry out have around undocumented criminality is not only conspicuously scant but likewise highly inconsistent. A 2018 report native the Cato Institute found that arrest and conviction prices for undocumented immigrants are reduced than those that native-born individuals (12). Research by the Crime avoidance Research center in that exact same year, however, got to the specific opposite conclusion (13). Neither of these studies was peer-reviewed, and also thus, your data and also methodologies have actually not been subject to clinical scrutiny. Provided the salience the this study for informing modern public and political dialogue, the time has actually come for a thorough inquiry right into the nexus between undocumented immigrants and crime.

Second, going past general differences in crime, we calculate comparative crime rates across multiple violation types. These distinctions are crucial for both theoretical and also empirical reasons. Despite the proof linking immigrants (generally) to violent crime is markedly thin (14), there room compelling theoretical reasons to think that undocumented immigrant may have actually divergent effects on violent and nonviolent crime. Many notably, lacking legal status boundaries their legitimate financial opportunities, and thus, undocumented immigrants may turn come illegitimate financial pursuits (15). Indigenous an empirical perspective, the commonwealth government’s enhancing reliance on collaborations v state and local law enforcement complicates the snapshot of immigrant criminality due to the fact that many immigrants organized in regional jails are booked on federal immigration charges, not neighborhood criminal charges. A focus on the in its entirety rates the crime obscures this crucial distinction.

Last, we study the overall and relative crime trends among the undocumented. The truth that we at this time cannot answer just how undocumented criminality has readjusted in recent years with even a directional explain (increasing or decreasing) is highly problematic, specifically in light of the substantial enforcement initiatives imposed under Presidents Obama and Trump come decrease the load of immigrant crime (4, 5). Making use of visual plots, linear regressions, and also time series techniques (augmented Dickey–Fuller tests), we provide a longitudinal assessment of the family member involvement the undocumented immigrants in crime.

Foreshadowing our results, we uncover that undocumented immigrant have significantly lower crime prices than native-born citizens and also legal immigrants throughout a variety of criminal offenses, consisting of violent, property, drug, and also traffic crimes. We also report no evidence that undocumented criminality has become much more prevalent in recent years throughout any crime category.
