Integrated Fertility Survey Series (IFSS) publishes second data releaseThe Integrated Fertility Survey Series (IFSS) project at ICPSR is pleased to announce the release of its second harmonized dataset, which updates the first release and adds variables related to union history, cohabitation and husband/partner sociodemographics. The dataset combines information from 10 surveys and over 71,000 respondents spanning 1955 to 2002 into harmonized variables for easy analysis.
Please note that all IFSS data releases are beta versions provided for users to begin using the data before the final version is released in late 2012. As such, they are subject to change and may contain small inconsistencies. If you notice any problems with the data, please contact the IFSS team at IFSSGroup@umich.edu so that we may fix them.
