Economist Jed Kolko has challenged recent claims that employment for U.S.-born workers has surged by millions, arguing the widely circulated figures misread the Current Population Survey. In a detailed brief, Kolko shows that more than half of the reported 2 million increase in native-born employment over the past year stems from a one-time population adjustment the Bureau of Labor Statistics applied to the survey in January 2025, rather than from genuine labour-market gains. Kolko notes that the CPS sample is too small to provide precise monthly estimates of foreign- and native-born employment levels—the July confidence interval for foreign-born employment alone spans about 1.4 million jobs. Because nativity is not a population control variable, shifts in survey response rates among immigrants mechanically inflate the native-born counts needed to make totals match Census projections, further distorting the data. A more reliable gauge, he says, is the unemployment rate. On that measure native-born workers are faring slightly worse than a year ago: their jobless rate rose to 4.7 % in July from 4.5 %, while the rate for foreign-born workers held steady at 4.1 %. Kolko urges analysts and policymakers to focus on such ratios and to avoid drawing conclusions from CPS employment levels until the statistical agencies revise their methodology.
