The first significant workforce composition is immigration, in the 1990s wave of immigrant workers was by far the largest in the past three decades, and contributed a larger share of the growth in the nation's labor force than at any other time since the end of World War II. Immigrants also accounted for all the growth among workers fewer than 35, which explained the drop in U.S. birthrates in the 1970s and the resulting dip in the U.S. born population in that young age group. But even among those ages 35 to 44, the youngest baby boomers, and new immigrants supplied a third of the growth in the labor force. This effect was particularly large among men; eight of 10 new male workers in the decade were immigrants who arrived during that time. Over the 1990-2001 time periods, the nation's civilian labor force increased from 125.8 million to 141.8 million, a gain of just fewer than 16 million or 12.7% over this 11 year period. The estimated number of new immigrant workers during the same period was 8.03 million; thus, new immigrants account for 50 percent of the growth in the nation's civilian labor force over the 1990-2001 time periods. Seventy-nine percent of the increase in the U.S. male civilian labor force between 1990 and 2001 was due to new male immigrants. Had it not been for immigrants, the report notes, the nation's entire male labor force would have grown only marginally over the past decade, and male labor shortages would likely have been widespread in many areas of the country. Firms in these industrial sectors employed 35 percent of all immigrant workers and nearly 40 percent of all new immigrants. But they also have an above average share of the nation's jobs in engineering, computer science and physical science. Many high technology industries in both manufacturing and in business services were highly
