Abstract:
This report describes estimates of the undocumented population residing in the United States in 2022 compiled by the Center for Migration Studies of New York (CMS). The estimates are based on data collected in the American Community Survey (ACS) conducted by the US Census Bureau (Ruggles et al. 2023). The report finds that the undocumented population grew from 10.3 million in 2021 to 10.9 million in 2022, an increase of 650,000. The increase reverses more than a decade of gradual decline. The undocumented populations from 10 countries increased by a total of 525,000: Mexico, the Dominican Republic, and India; El Salvador, Guatemala, and Honduras in Central America; and Brazil, Colombia, Ecuador, and Venezuela in South America. The undocumented population in Florida increased by about 125,000 in 2022, Texas increased by 60,000, New York by 50,000, and Maryland by 45,000. The report explains why undocumented population growth is much less than the number of apprehensions by DHS. Finally, the Appendix provides a detailed description of the CMS methodology. • After remaining at or near zero growth from 2010 to 2021 (Warren 2023), the US undocumented population increased by 650,000 in 2022. • The largest population gains in 2022 were for Central America (205,000), South America (200,000), and Asia (140,000). • From 2015 to 2022, the undocumented population from Mexico declined by 1.3 million; in the same period, the combined population from Central and South America increased by 1.2 million. • The undocumented population from Asia declined by 115,000 from 2015 to 2021 and then increased by 140,000 in 2022. • California, Texas, Florida, New York, and New Jersey had the largest undocumented populations in 2022. The total population in those five states increased by 300,000 in 2022. • The combined undocumented population from El Salvador, Guatemala, and Honduras was undercounted by almost 400,000 in 2022. Correcting this data accounted for more than half the estimated increase in the undocumented population in 2022.

Abstract:
In 2021, the undocumented population residing in the United States (US) increased slightly to 10.3 million, compared to 10.2 million the previous year. The gradual decline or near-zero growth of this population has continued for more than a decade. However, the large increases in apprehensions at the southern border in recent years, along with continued legislative gridlock in Congress, could portend a new era of growth of this population. Unfortunately, the data needed to determine whether the population will enter a period of growth after 2021 — or whether the era of near-zero growth will continue — will not be available for at least a year or two. The most accurate demographic estimates of the undocumented population are derived from data collected in the US Census Bureau’s American Community Survey. Estimates of the size of the undocumented population in 2022 will not be available until early 2024. This report focuses on the most significant trend in the undocumented population in the past decade — the remarkable decline of 1.9 million in the undocumented population from Mexico from 2011 to 2021. The decline for Mexico in this period was 600,000 more than the total population increase from the seven countries (in order) with the fastest growing US undocumented populations: Guatemala, Honduras, India, Venezuela, El Salvador, Brazil, and China. This paper finds that: • The long-term decline, or near-zero growth, of the total undocumented population that began in 2008 continued in 2021. • The percent of undocumented residents in the total US population declined from 3.8 percent in 2011 to 3.1 percent in 2021. • The undocumented population from Mexico declined from 6.4 million in 2011 to 4.4 million in 2021, a drop of 1.9 million in 10 years. • A total of 2.9 million, or 47 percent, of the US undocumented population from Mexico in 2011 had left the undocumented population by 2021. • The drop in the undocumented population from Mexico from 2011 to 2021 occurred nationwide, and the decline affected the undocumented population in nearly every state. • The fastest growing undocumented populations by country in the last 10 years were from Guatemala, Honduras, India, El Salvador, Venezuela, and Brazil. The combined undocumented populations from these six countries grew by 1.2 million. • Countries that had declining populations after 2011 included Poland, Peru, Ecuador, Korea, and Philippines, in addition to the large drop for Mexico. • California had the largest decline in undocumented residents — 665,000 from 2011 to 2021. The undocumented population from Mexico living in California during this period declined by 720,000. • The combined undocumented population in California, New York, and Illinois fell by more than one million from 2021 to 2011.

3. 2020 American Community Survey: Use with Caution, An Analysis of the Undercount in the 2020 ACS Data Used to Derive Estimates of the Undocumented Population

Abstract:
This paper analyzes and provides estimates of the undercount of the foreign-born in the US Census Bureau’s 2020 American Community Survey (ACS). It confirms that a differential undercount occurred in the 2020 ACS. In particular, noncitizens that arrived from Central American countries after 1981 had undercount rates of 15–25 percent, but undercount of noncitizens that arrived from European countries in the same period was not detectable by the methods described in this paper. The Center for Migration Studies of New York (CMS) and others use ACS data to derive annual estimates of the US undocumented population. The Census Bureau recently reported that the total population count for the 2020 Census was consistent with the count for recent censuses, despite the Covid-19 pandemic and the Trump administration’s interference in the 2020 Census. Nonetheless, the accuracy of 2020 ACS data for the noncitizen population that arrived after 1981 remains a major concern given the fear generated by the Trump administration’s abusive rhetoric and anti-immigrant policies. The estimates set forth in this paper were derived by analyzing trends in annual ACS data for 2016–2020 compiled from the IPUMS website (Ruggles et al. 2021). Decennial census data cannot be used for this purpose because data on country of birth, citizenship, and year of immigration are not collected in the census. However, it is reasonable to believe that the 2020 census and the 2020 ACS experienced similar challenges because they were conducted under comparable conditions. The patterns of undercount of noncitizens described here for the 2020 ACS are likely mirrored in the 2020 census and will reduce federal funding and representation to affected cities and states for the next decade.

4. In 2019, the US Undocumented Population Continued a Decade-Long Decline and the Foreign-Born Population Neared Zero Growth

Abstract:
This report presents new estimates of the undocumented population residing in the United States in July 2019, by country of origin and state of residence. The Center for Migration Studies (CMS) derived the estimates by analyzing data collected in the annual American Community Survey (ACS) conducted by the US Census Bureau (Ruggles et al. 2020). The methodology used to estimate the undocumented population is described in the Appendix. The report highlights an aspect of population change — the number leaving the population — that is often overlooked in discussions of immigration trends. The report shows that the annual numbers leaving the population, especially through return migration to Mexico, have been the primary determinant of population change in the undocumented population in the past decade. Increasing numbers leaving the population have also led to near-zero growth of the total foreign-born population, which grew by just 20,000 from July 2018 to June 2019, the slowest growth in that population in more than a half-century.

Abstract:
COMMENTARYACCESS TO ABORTION FOR UNDOCUMENTED PERSONS DURING THE COVID-19 PANDEMICFRÉDÉRIQUE CHABOT*Action Canada for Sexual Health and Rights (‘Action Canada’) is a national organisation committed to advancing and upholding sexual and reproductive health and rights in Canada and globally. Building on the 50-year legacy of the organisations that formed Action Canada, we work to promote health, equity, wellbeing and rights related to sexuality and reproductive health to advance progressive policies on access to abortion, stigma-free healthcare, gender equality, LGBTQ+ rights and inclusive sex-ed, among other issues that intersect with bodily autonomy, gender, sexuality and reproduction.In March 2020, as the world quickly pivoted towards a pandemic response, Action Canada connected with partners across the country to monitor shifting needs and how providers of sexual and reproductive health services were adaptingto this novel situation in Canada. We saw some concerning gaps in services leading to a disproportionate impact on stateless and undocumented persons.1Action Canada’s activities include the operation of a 24-hour toll-free pregnancy information and referral service — the Access Line — paired with a national abortion fund to ensure those who face barriers can access abortion care. Calls to the Access Line more than doubled in the first months of 2020. Callers were looking for ways to access safe abortions during the pandemic. Conference calls with our network of sexual health centres across the country, surveys to partners and a variety of national organisations revealed concerning trends in relation to stateless persons and those with precarious immigration status and their ability to access sexual and reproductive health care.
