How many illegal immigrants are in the US is one of the most frequently asked questions in current policy debates, and the latest verified estimates show the number remains around 10.5 million to 11 million people as of recent data available in 2025–2026. While border encounters have increased in recent years, the total unauthorized population inside the country has stayed relatively stable compared to past decades.

Current Estimated Number of Unauthorized Immigrants
Recent demographic analyses indicate:
- Total estimated population: 10.5–11 million
- Share of U.S. population: About 3%
- Workforce participation: Roughly 7–8 million are part of the labor force
These figures reflect people living in the U.S. without legal immigration status, including those who overstayed visas and those who entered without authorization.
Why the Number Has Remained Stable
Even with rising border crossings reported in 2023–2025, the total number has not sharply increased. Several factors explain this:
- Deportations and removals continue each year
- Voluntary returns reduce net growth
- Legal status adjustments move some individuals out of the unauthorized category
- Lower long-term settlement rates compared to earlier decades
This balance keeps the overall figure relatively steady.
Where Most Unauthorized Immigrants Live
The population is not evenly distributed across the country. Most individuals live in a few key states:
- California – Largest share
- Texas – Significant population tied to border proximity
- Florida – Rapid recent growth
- New York and New Jersey – Major urban hubs
Large metro areas attract workers due to job availability in construction, hospitality, agriculture, and service industries.
Countries of Origin
Unauthorized immigrants in the U.S. come from many regions, though the majority originate from nearby countries.
Top regions include:
- Mexico (largest single group)
- Central America (Guatemala, Honduras, El Salvador)
- South America
- Asia (including visa overstays)
Migration patterns have become more diverse in recent years, with increasing arrivals from outside Latin America.
Border Crossings vs. Total Population
It is important to distinguish between annual border encounters and the total number of unauthorized immigrants living in the U.S.
- Border encounters reached record highs in 2023 and remained elevated into 2024–2025
- Many individuals are:
- Processed under immigration proceedings
- Returned or removed
- Not permanently added to the resident population
This explains why increases at the border do not directly translate into a sharp rise in the total population.
Breakdown by Length of Stay
A large portion of unauthorized immigrants have lived in the U.S. for many years.
- Long-term residents (10+ years): Nearly half
- Recent arrivals (last 5 years): Growing share
- U.S.-born children in mixed-status families: Millions
This highlights that the issue involves both recent migration and long-established communities.
Economic Impact
Unauthorized immigrants play a measurable role in the U.S. economy.
Key contributions include:
- Filling labor shortages in agriculture, construction, and service industries
- Paying billions annually in state and local taxes
- Supporting industries dependent on manual and seasonal labor
At the same time, debates continue over public service costs such as healthcare and education.
How the U.S. Estimates This Population
There is no official real-time count of unauthorized immigrants. Estimates are calculated using:
- Census-based population data
- Immigration records
- Statistical modeling techniques
These approaches provide consistent and widely accepted ranges, even though exact totals may vary slightly.
Policy Debate in 2026
The question of how many illegal immigrants are in the US remains central to ongoing political discussions.
Major policy areas include:
- Border security measures
- Asylum system reforms
- Work authorization policies
- Potential pathways to legal status
As of early 2026, comprehensive federal immigration reform has not been enacted.
Key Takeaways
- The U.S. has about 10.5–11 million unauthorized immigrants
- The number has remained relatively stable in recent years
- Border crossings do not equal permanent population growth
- Many individuals are long-term residents contributing to the workforce
Understanding how many illegal immigrants are in the US helps clarify one of the most debated issues in the country today, but the numbers alone do not tell the full story of policy, economics, and long-term impact.
