Frequently Requested Statistics on Immigrants and Immigration in the United States
Key Takeaways
- The Migration Policy Institute (MPI) has compiled a one-stop set of frequently requested immigration statistics covering population, legal status, admissions, and integration measures.
- Data cover multiple groups: lawful permanent residents (green card holders), refugees and asylees, temporary programs (DACA, TPS), naturalizations, and estimates of unauthorized immigrants.
- The compendium is a practical resource for applicants, attorneys, journalists, and policymakers seeking context on processing times, backlogs, and long-term trends.
- Users should note methodological differences between data sources; it has been reported that some estimates (especially of unauthorized residents) rely on modeling and vary by source.
What the compendium contains
MPI’s “Frequently Requested Statistics” assembles headline figures and charts that policymakers and practitioners commonly ask for: the size and composition of the foreign-born population, country-of-origin shares, state-level distributions, admissions of refugees and lawful permanent residents, naturalization rates, and counts for special programs such as DACA (Deferred Action for Childhood Arrivals) and TPS (Temporary Protected Status). The brief also points readers to primary data sources — U.S. Census Bureau, Department of Homeland Security, Department of State, and U.S. Citizenship and Immigration Services (USCIS) — and explains basic terms like LPR (lawful permanent resident, or “green card” holder) and asylum seeker.
Why this matters for people navigating the system
For someone applying for a visa, green card, or citizenship, these statistics provide context: which countries dominate backlogs, how many people are naturalizing each year, and where unauthorized populations are concentrated. That context can shape expectations about wait times, the competitiveness of employment-based categories, or the scale of humanitarian admissions. Policymakers and advocates also use these numbers to argue for rule changes, funding for adjudications, or targeted services in high-immigrant communities. Practically, applicants should still rely on USCIS and Department of State case-specific guidance for processing timelines and fee information, since aggregated statistics do not substitute for individualized case tracking.
Limitations and practical next steps
Data compilations are useful but not definitive. Different agencies use different definitions and collection methods; estimates of unauthorized immigrants, in particular, vary and often depend on statistical models. It has been reported that year-to-year comparisons can reflect methodological changes as much as real shifts. For immigrants and sponsors: use MPI’s compendium as a roadmap to primary sources, monitor USCIS processing times and Federal Register notices for fee or rule changes, and consult an immigration attorney for case-specific advice.
