As of 1990, there were nearly 20 million foreign-born persons in the United States. Nearly half came in the previous 10 years, and nearly one in six came in the previous three years.
Net immigration has been around the one-million-a-year level over the past decade. Current projections assume around 900,000 per year, of which 200,000 are undocumented. As you can see, that may be a little low compared to recent experience. We are currently working on revisions to the projections that may well increase that level to be more consistent with the recent experience.
