Survey-based estimates indicate a decline of roughly 2. 9 million in the U.S. Foreign-born population from January 2025 to July 2026, while a preliminary estimate puts the unauthorized immigrant decline at 2. 3 million.
But the figures do not establish that 2. 2 million immigrants physically left the country, and they do not measure the population on September 9.

The Current Population Survey-based analysis estimated that the foreign-born population fell by about 2.9 million between January 2025 and July 2026, while estimating a 2.3 million decline in the unauthorized immigrant population.
The cited period ends in July 2026, so it does not establish the number of immigrants in the United States on September 9, 2026.
Researchers cautioned that survey population changes do not necessarily represent people physically leaving the country, because survey coverage, response patterns and Census population controls can affect the estimates.
The closest available evidence comes from the Current Population Survey, which the Center for Immigration Studies used to estimate that the foreign-born population fell from about 53.3 million in January 2025 to 50.4 million in July 2026, a decline of approximately 2.9 million. The same analysis preliminarily estimated a 2.3 million decline in the unauthorized immigrant population. Those figures make a claim of roughly 2.2 million fewer immigrants broadly consistent with one survey-based estimate, but they do not match the claim precisely or establish that the change occurred through departures.

The timing and wording are also significant. The underlying estimate covers January 2025 through July 2026, not January through September 9, 2026, and it concerns the estimated foreign-born population, a category that includes legal immigrants, unauthorized immigrants and other people born abroad. The Washington Times reported, citing the Center for Immigration Studies' calculations, that the legal immigrant population also declined by about 600,000 during that period.

Researchers have cautioned against treating the survey change as a direct count of people who left the United States. The Peterson Institute for International Economics noted that Current Population Survey estimates are affected by population controls set by the Census Bureau, meaning a reported fall in the foreign-born population can be accompanied by a mechanically offsetting increase in the estimated native-born population. The American Remnant likewise noted that a decline in the survey estimate is not necessarily equivalent to 2.9 million foreign-born residents physically leaving the country.

The broader source record supports a substantial survey-measured decline, but it does not support the stronger, present-tense interpretation that there are definitively 2.2 million fewer immigrants in the country today than in January. The claim lacks a precise population definition, uses a date that extends beyond the latest cited data, and presents an estimate of population change as if it were a verified count of departures.
The best-supported verdict changes from True to Misleading. The newer evidence does support a substantial survey-estimated decline in the foreign-born population, but it measures January 2025 to July 2026 rather than the population on September 9, 2026, reports about 2.9 million rather than 2.2 million, and does not establish that 2.2 million immigrants physically left the United States. It also identifies methodological limitations in treating CPS population changes as a direct count of departures.
