Study of American Families, 1994In the DISC Archive of the University of Wisconsin-Madison. Can be used with the GSS
Abstract from the site: "The 1994 Study of American Families (SAF), conducted at the University of Wisconsin-Madison, is a telephone survey of randomly selected siblings of respondents to the 1994 General Social Survey (GSS). Because the SAF replicated nearly all GSS items (and added many more), researchers can combine the GSS and SAF data to study patterns of sibling resemblance in socioeconomic, attitudinal, family, cognitive ability, and other outcomes. Support for the SAF came from the Sociology Program of the National Science Foundation. For more information about the data set, read the study description."
