The general trends of change in South Dakota's population have continued during the 1950-60 decade. The State's total population was enumerated in 1960 as 680,514 persons, a 4.3% gain during the ten year period. This total gain in the South Dakota population was greater than those which have occurred during each of the previous three decades. This 1950-60 increased total growth has led many South Dakotan's to believe that the rate of net out-migration of South Dakota's population during the 1930’s and 1940's must be slowing down or even decreasing. But to the contrary, South Dakota's net outmigration during the 1950-60 decade, although less than in the 1930's, increased over the 1940-50 decade. Whereas South Dakota lost 79,035 persons during the 1940-50 decade (12.3% of the 1940 population) due to net out-migration, during the 1950-60 decade the State's loss through net out-migration amounted to 93,962 or 14.4% of the total 1950 population.
