Foreign-Born Population in the US
The United States has long been a destination for immigrants, and the foreign-born population is at an all-time high. According to Pew Research Center data, 53.3 million immigrants lived in the United States in January 2025 1.
This represents the largest number in US history, surpassing previous peaks from the early 20th century. The Center for Immigration Studies confirms this finding 2.
The Census Bureau tracks these numbers through the American Community Survey and other demographic surveys 3.
Foreign-Born Share of Population
The foreign-born share of the US population reached 15.6% in 2024—an all-time high 4. While significant, this is not unprecedented in American history, as the foreign-born share was similar in the early 20th century.
This growth reflects:
- Increased immigration from Latin America, Asia, and Africa
- Lower emigration of immigrants back to their home countries
- Natural increase among immigrant populations
Pew Research provides ongoing tracking of these demographic trends 5.
Net Immigration Rates
Net immigration—the number of immigrants entering minus the number leaving—has fluctuated in recent years. According to CBO data:
| Year | Net Immigration |
|---|---|
| 2022 | 2.0 million |
| 2023 | 2.4 million |
| 2024 | 1.8 million |
The decline from 2.4 million in 2023 to 1.8 million in 2024 reflects changing policies, economic conditions, and border enforcement measures.
The Center for Immigration Studies provides additional analysis of these trends 7. DHS Office of Homeland Security Statistics tracks these flows 8.
Immigration Growth Since 2022
The foreign-born population has grown substantially in recent years. From January 2022 to January 2025, the foreign-born population increased by 6.74 million people 9.
This rapid growth reflects:
- Post-pandemic immigration surge as borders reopened
- Policy changes affecting asylum and refugee processing
- Economic migration driven by US labor market conditions
The CBO projects continued growth, though at potentially slower rates depending on policy 10.
Immigrants and US-Born Children
Immigrants and their descendants represent a significant portion of the US population. According to estimates, immigrants and their US-born children numbered more than 93 million people in 2024 11.
This “immigrant-origin population” includes:
- First-generation immigrants (foreign-born)
- Second-generation (US-born with at least one foreign-born parent)
- Later generations with immigrant ancestry
The DHS Yearbook of Immigration Statistics provides comprehensive data on immigration flows 12.
Unauthorized Immigration
Unauthorized immigrants represent a significant portion of the foreign-born population. According to Pew Research Center, the unauthorized immigrant population reached approximately 14 million in 2023—the highest level on record 13.
The Migration Policy Institute provides additional analysis of unauthorized immigration trends 14. The Center for Migration Studies estimates this population using Census Bureau data 15.
Characteristics of Unauthorized Immigrants
Unauthorized immigrants come from primarily:
- Mexico and Central America (largest regional share)
- Other Latin American countries
- Asia (growing share)
- Other regions
They work in various sectors including:
- Agriculture
- Construction
- Food service
- Healthcare support
- Domestic work
Asylum Backlog and Immigration Courts
The asylum system faces significant backlogs. According to the American Immigration Council:
- As of December 31, 2024, there were 1,446,908 affirmative asylum applications pending with USCIS
- Immigration courts had over 3.7 million open removal cases as of January 31, 2025
TRAC Reports provides detailed court backlog data 17. Congress.gov tracks legislative responses to these challenges 18.
Immigration Court Backlog
The immigration court backlog represents one of the most significant challenges in the immigration system. Cases can take years to resolve, creating uncertainty for:
- Asylum seekers
- Families awaiting deportation hearings
- Employers seeking to hire immigrant workers
- Local communities affected by delays
Refugee Admissions
The refugee admissions program sets annual ceilings for humanitarian immigration. The FY2024 and FY2025 refugee admissions ceiling was set at 125,000—the highest level since 2016 19.
This represented a significant increase from the lower ceilings set in the Trump administration years. The Center for Immigration Studies notes this was the highest level under the Biden-Harris administration 20.
Pew Research provides context on refugee admissions trends 21.
Refugee vs. Asylum
It’s important to distinguish between refugees and asylum seekers:
- Refugees are processed overseas through the US Refugee Admissions Program (USRAP)
- Asylum seekers apply for protection after arriving in the US (or at a port of entry)
Both pathways provide protection to people fleeing persecution, though the processes differ significantly.
