What effect did immigration from the United States have on the growth of Texas? (p.169)

Between 1990 and 1994, over 300,000 legal immigrants settled in Texas. In addition, we estimate that during that same period Texas received a net annual increase from illegal immigration of at least 30-50,000. Thus, immigration accounted directly for perhaps 35 percent of all the growth in that five-year period.
