This statistic shows the estimated percentage of employed undocumented immigrants in the United States in 2016, distinguished by industry. In 2017, around 14.2 percent of agriculture workers were estimated to be undocumented immigrants.
In 2022, an estimated 10.99 million unauthorized immigrants were living in the United States. This is an increase from about 3.5 million unauthorized immigrants who lived in the United States in 1990.

This study was conducted to examine whether a rising crime rate in El Paso, Texas and San Diego, California in 1986 could be attributed to, among other factors, the influx of undocumented aliens. Variables include level of involvement of undocumented aliens in serious felony arrests in San Diego and El Paso Counties, the outcome of serious felony arrest cases involving undocumented persons compared to others arrested for similar offenses, the impact of arrests of undocumented aliens on the criminal justice system in terms of workload and cost, the extent that criminal justice agencies coordinate their efforts to apprehend and process undocumented aliens who have committed serious crimes in San Diego and El Paso counties, and how differences in agency objectives impede or enhance coordination. Data are also provided on how many undocumented persons were arrested/convicted for repeat offense in these counties and which type of policies or procedures could be implemented in criminal justice agencies to address the issue of crimes committed by undocumented aliens. Data were collected in the two cities with focus on serious felony offenses. The collection includes sociodemographic characteristics, citizenship status, current arrest, case disposition, and prior criminal history with additional data from San Diego to compute the costs involving undocumented aliens.
In January 2022, it was estimated that about 1.85 million male illegal immigrants living in the United States were aged between 35 and 44 years old. In that same year, it was estimated that 1.52 million female illegal immigrants living in the U.S. were between 35 and 44 years old.
This statistic shows the public opinion in the United States on whether undocumented immigrants were more likely to commit crimes than American citizens, as of 2018. As of 2018, 69 percent of respondents thought that undocumented immigrants were not more likely to commit crimes than American citizens.

The following table is imported from the 2019 Yearbook of Immigration Statistics under the Department of Homeland Security:
The 2019 Yearbook of Immigration Statistics is a compendium of tables that provide data on foreign nationals who are granted lawful permanent residence (i.e., immigrants who receive a “green card”), admitted as temporary nonimmigrants, granted asylum or refugee status, or are naturalized. The Yearbook also presents data on immigration enforcement actions, including apprehensions and arrests, removals, and returns.
Table 39. Aliens Removed or Returned: Fiscal Years 1892 to 2019 (https://www.dhs.gov/immigration-statistics/yearbook/2019/table39)
The data was collected to observe trends in history reflecting the number of immigrants deported - more specifically removed or returned.
This statistic shows the estimated GDP loss if all illegal immigrant workers were removed from the United States. As of September 2016, the manufacturing industry would suffer an estimated 74 billion U.S. dollar decline in GDP output if all illegal immigrant workers were removed from the U.S.

The estimated population of unauthorized immigrants in the U.S. stands at around ** million people. Although the number has stabilized, the United States has seen a spike in migrant encounters in the last few years, with over * million cases registered by the U.S. Border Patrol in 2023. This is a slight decrease from the previous year, when there were over *** million cases registered. Due to its proximity and shared border, Mexico remains the leading country of origin for most undocumented immigrants in the U.S., with California and Texas being home to the majority.
Immigration and political division
Despite the majority of the population having immigrant roots, the topic of immigration in the U.S. remains one of the country’s longest-standing political debates. Support among Republicans for restrictive immigration has grown alongside Democratic support for open immigration. This growing divide has deepened the polarization between the two major political parties, stifling constructive dialogue and impeding meaningful reform efforts and as a result, has led to dissatisfaction from all sides. In addition to general immigration policy, feelings toward illegal immigration in the U.S. also vary widely. For some, it's seen as a significant threat to national security, cultural identity, and economic stability. This perspective often aligns with support for stringent measures like Trump's proposed border wall and increased enforcement efforts. On the other hand, there are those who are more sympathetic toward undocumented immigrants, as demonstrated by support for the Deferred Action for Childhood Arrivals (DACA) program.

The day-to-day behaviors of undocumented immigrants are significantly affected when local law enforcement officials do the work of federal immigration enforcement. One such behavior, which has been widely discussed in debates over sanctuary policies, is that undocumented immigrants are less likely to report crimes to the police when local law enforcement officials work with U.S. Immigration and Customs Enforcement (ICE) on federal immigration enforcement. However, the mechanism that explains this relationship, which is decreased trust in law enforcement, has not yet been systematically tested. Do undocumented immigrants become less trusting of police officers and sheriffs when local law enforcement officials work with ICE on federal immigration enforcement? To answer this question, we embedded an experiment that varied the interior immigration enforcement context in a survey (n = 512) drawn from a probability-based sample of undocumented immigrants. When local law enforcement officials work with ICE on federal immigration enforcement, respondents are statistically significantly less likely to say that they trust that police officers and sheriffs will keep them, their families, and their communities safe, protect the confidentiality of witnesses to crimes even if they are undocumented, protect the rights of all people, including undocumented immigrants, equally, and protect undocumented immigrants from abuse or discrimination.
A ‘small boat’ is one of a number of vessels used by individuals who cross the English Channel, with the aim of gaining entry to the UK without a visa or permission to enter – either directly by landing in the UK or having been intercepted at sea by the authorities and brought ashore. The most common small vessels detected making these types of crossings are rigid-hulled inflatable boats (RHIBs), dinghies and kayaks.
