Nearly 1 in 11 Americans are foreign-born.  In 1994, 8.7 percent of the population of the United States was foreign-born — nearly doublet he percent foreign-born in 1970 (4.8 percent). While the percent foreign-born is at its highest level since before World War II, much greater proportions of the U.S. population were foreign-born during the early part of this century. From a high of 14.7 percent in 1910, the percent foreign-born declined to a low of 4.8 percent in 1970. Since that time, the percent has steadily increased.
