We use data from multiple national surveys to describe trends in private elementary school enrollment by family income from 1968 to 2013. We find several important trends. First, the private school enrollment rate of middle-income families declined substantially over the past five decades while that of high-income families remained quite stable. Second, there are notable differences in private school enrollment trends by race/ethnicity, urbanicity, and region of the country. Although racial/ethnic differences in private school enrollment are to a large extent explained by income differences, the urban/suburban and regional differences in private school enrollment patterns are large even among families with similar incomes. Factors contributing to these patterns may include trends in income inequality, private school costs and availability, and the perceived relative quality of local schooling options
