Emerging from the 1950 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 percent, lowest in American annual records except for the Depression years.
Americans have been migrating south and west in larger number since World War Ⅱ, and the pattern still prevails.
Three sun belt states--Florida, Texas and California--together had nearly 10 million more people in 1980 than a decade earlier. Among large cities,
A. California was once the most thinly populated area in the whole US
B. the top 10 states in growth rate of population were all located in the West
C. cities with better climates benefited unanimously from migration
D. Arizona ranked second of all states in its growth rate of population
