Source: Centers for Disease Control and Prevention natality public-use data. The data from 2003-2006 and 2007-2015 are not strictly comparable, given that in the earlier period educational attainment is measured by years, whereas in the later period it is measured using discrete categories (bachelor’s degree, master’s degree, doctorate or professional degree, etc.); see the CDC’s data summary for more information. To address this problem, I have used broad, composite categories in this chart (12 or fewer years of education, equivalent to a high school degree or less education, and 16 or more years of education, equivalent to a bachelor’s degree or more education).
