Note: To be included, the survey had to include information about the socioeconomic circumstances of at least two generations observed mid-career. For surveys with no maximum age at first interview, this figure assumes (for the sake of simplicity) a maximum age of 90.
1Children of PSID sample members are here counted as themselves being in the PSID upon their birth or adoption.
2Other NCES panels—e.g., NLS-72—are not included because the panels are inactive and/or respondents are not (yet) observed mid-career
3This assumes that the planned 2014 SIPP panel will include content on parents' and/or children's socioeconomic circumstances
