In three decades the immigrant population in the U.S. has increased from 10 million to more than 28 million and continues to grow. In 1970 the foreign-born population was little more than 4%; today it has reached 11 %. About 40% of the immigrant population growth in this 35-year period has occurred in the past decade alone. The consensus among demographers is that immigrants are the major contributor to the country's population growth.
