First, for college graduates, the percentage of marriages that are ongoing at 10 and 15 years exceeds the percentages among the other education groups. At 15 years, 75 percent of the marriages of college graduates are ongoing compared with 55–60 percent of marriages among those with less than a college degree. Second, with the exception of marriages that began between ages 41 and 46, divorce rates generally decline as educational attainment increases. For instance, of those marriages that began from ages 23 to 28, the proportion that ended in divorce was 54 percent for those with less than a high school diploma, 50 percent for high school graduates with no college, 46 percent for high school graduates with some college, and 31 percent for college graduates. A similar pattern occurs among marriages that began from ages 35 to 40: the proportion that ended in divorce was 31 percent for those with less than a high school diploma, 25 percent for high school graduates with no college, 26 percent for high school graduates with some college, and 13 percent for college graduates.
