To help place the SRE findings into perspective, the analyses began with a comparison of demography across fathers, mothers, sons and daughters in the 107 families that contributed to these data. As shown in the upper portion of Table 1, the large majority of subjects self-reported an EA heritage. Within generations, fathers and mothers were about age 40 at the time of filling out the SRE (mothers filled out the SRE about three years later than fathers), and sons and daughters about age 28. In these relatively highly educated families, fathers had more years of education than mothers, and daughters more years of education than sons. Looking across generations, the fathers were more highly educated than sons, although mothers and daughters reported similar years of education.
