How does mass immigration contribute to the U.S. population growth?
Since 1987, legal immigration has averaged about 1 million a year. According to conservative estimates, about 400,000 illegal immigrants enter the U.S. annually. An analysis of Census data by the Center for Immigration Studies shows that nearly 70 percent of the population growth between 1990 to 2000 was immigration-related. Our federal government also grants many categories of “temporary” working visas to foreign-born professionals and most of them stay permanently in the U.S.
