The following four hypotheses were tested: (1) nonmetropolitan areas with the highest percentages employed in industry in 1960 will experience the greatest inmigration between 1965-70; (2) those with a high percentage employed in agriculture will experience the lowest amounts of inmigration; (3) those areas with small farm size and low farm income in 1960 will experience low inmigration rates; and (4) nonmetropolitan areas close to metropolitan centers will experience the highest rates of inmigration. Employing the nonmetropolitan State Economic Area (SEA) unit and utilizing U.S. census data, migration rates were calculated for each of the nonmetropolitan SEA's in Texas, Louisiana, Oklahoma, and Arkansas. Total inmigration, inmigration from the nonmetropolitan and metropolitan SEA's, and net migration were calculated for the population 5 years and older in 1970. Some results were: positive correlation between inmigration and net migration and percent employed in industry but negative correlation between inmigration and net migration and percent employed in agriculture; negative correlation between inmigration and agriculture regardless of size of farm; and positive correlation between net migration and proximity to large Standard Metropolitan Statistical Areas.
