Emerging from the 1980 census is the picture of a nation developing more and more regional competition, as population growth in the Northeast and Midwest reaches a near standstill. This development -- and its strong implications for US politics and economy in years ahead -- has enthroned the South as America's most densely populated region for the first time in the history of the nation's head counting. Altogether, the US population rose in the 1970s by 23.2 million people -- numerically the third largest growth ever recorded in a single decade. Even so, that gain adds up to only 11.4%, lowest in American annual records except for the Depression years.
1980年美国人口普查显示出这样一幅图像：随着东北部和中西部人口增长近乎停止，地区间的竞争越来越激烈了。 这一发展--以及它对今后美国政治和经济的强大影响--使南部地区在美国人口普查史上首次成为人口最密集的地区。 20世纪70年代，美国人口总共增长了2 320万--从数字上看，这是有历史记载以来10年期间内人口增长的第三高。即使如此，人口总数也只增加了11.4%，除了大萧条时期，这是美国年度记录中最低的增长率。
