Fact check: What are cities that are high illegal immigrants in the U.S?

Checked on September 9, 2025

1. Summary of the results

The original statement inquires about cities with high numbers of illegal immigrants in the U.S. According to [1], the top 5 metro areas with the largest unauthorized immigrant populations as of 2016 are the New York Metro Area, Los Angeles Metro Area, Houston Metro Area, Dallas Metro Area, and Miami Metro Area [1]. [2] reports that the U.S. unauthorized immigrant population reached a record 14 million in 2023, with the largest populations found in California, Texas, Florida, New York, and New Jersey [2]. [3] lists specific cities identified as sanctuary jurisdictions, including Los Angeles, CA, New York City, NY, and Chicago, IL, which may have high numbers of illegal immigrants due to their sanctuary policies [3]. [1] provides a list of the top 20 metro areas with the largest unauthorized immigrant populations as of 2016, along with the population and change since 2007, showing that 61% of all undocumented immigrants in the U.S. were located in these 20 metro areas [1].

2. Missing context/alternative viewpoints

A key point missing from the original statement is the economic and social impact of undocumented immigrants on the cities they reside in, as highlighted by [4], which states that removing them would hurt not just them but the entire city and country [4]. Another missing context is the sanctuary policies of certain cities, which may attract and harbor illegal immigrants, as mentioned by [5] [5]. Additionally, the original statement does not consider the integration of undocumented immigrants into the US economy, as reported by [2], which notes that they contribute to the economy through their work and tax payments [2]. Alternative viewpoints include the perspective of cities that benefit from sanctuary policies, such as Los Angeles and New York City, as well as the viewpoint of the US government, which has launched immigration enforcement operations in certain cities, as mentioned by [5] [5].

3. Potential misinformation/bias in the original statement

The original statement may be misleading in its assumption that cities with high numbers of illegal immigrants are necessarily problematic or undesirable, as it does not consider the economic and social benefits of undocumented immigrants, as highlighted by [4] [4]. The statement may also be biased towards a negative view of undocumented immigrants, as it does not acknowledge their contributions to the US economy, as reported by [2] [2]. Furthermore, the statement may be incomplete in its failure to consider the complex issues surrounding immigration and sanctuary policies, as discussed by [3] and [5] [3] [5]. The US government and anti-immigration groups may benefit from this framing, as it supports a narrative of undocumented immigrants as a problem to be solved, rather than as contributors to the US economy and society [2] [5].
