Estimating the number of foreign born persons in the United States has become much more complicated. I will post tomorrow an analysis of the difficulties in measurement.  The Congressional Budget Office estimated in July that during the Biden administration the numbers shot up to about 3 million a year, 9 million under Biden, or about 1% of the total population per year.   

This rate of 1% of the total population per year us what Canada has experienced purposefully for some years in its policy to attract talented persons as well as to admiy refugees.

This estimate is much higher than past ones. The Federal Reserve Bank of Dallas writes that there is “no consensus” as to the number of foreign-born who have entered recently.

The Wall Street Journal, using a study by the, estimates the net growth of foreign-born persons during the Biden administration at nine million persons.  At about 3 million persons per year, that comes to triple the annual volume of pre-Biden years of roughly one million. Green card migration was at or below past trends.  The increase is almost entirely due to undetected unauthorized entries and to  humanitarian programs—asylum, Humanitarian Parole and Temporary protected Status.

The WSJ article notes a change in the educational distribution of Biden are immigration. Prior to 2010, immigrants formed an hour-glass profile of formal educational attainment: many without a high school degree, relatively few with a high school degree, and a good share with an advanced degree. After 2010 the flow of migrants shifted from Latin Americans to more highly educated cohorts, for instance from East Asia and, surprisingly, Nigeria. You show that under Biden the profile went back to the old model.
