Notes: Summary statistics for the primary analytic sample, which consists of 8,537 individuals from the HRS. The sample is limited to individuals of European ancestry genotyped in the 2006 and 2008 waves. The earning data consist of 96,721 person-year observations for 3,140 men from our sample with nonmissing earnings data from the Social Security Administration Master Earnings File (MEF). These summary statistics are calculated without sampling weights. Missing values for the socioeconomic status variables include the responses “Don’t Know”, as well as cases where a response was not ascertained or the question was not asked.
