Do new survey data narrow the gap between competing immigration estimates?
Core argument: The 2023 American Community Survey reported 1.7m foreign-born residents who were abroad one year earlier, the key input into the Census Bureau's immigration estimate.
The 2023 [Census Bureau’s American Community Survey] reported 1.7m foreign-born residents who were abroad one year ago, which is the key input into the Census immigration estimate. That key input has been highly correlated with the final revision of the Census immigration estimate since 2010 (the correlation is .91). If this strong prior relationship holds, I estimate that the new ACS figure of 1.7m foreign-born, abroad one year ago, implies that the Census population estimate for 2023 will be revised to over 1.4m. That’s 300,000 more than the original Census 2023 immigration estimate of 1.1mm published in December 2023, but still way below the CBO’s 2023 estimate of 3.3mm.
