The Wisconsin Longitudinal Study is part of the Center for Demography of Health and Aging at the University of Wisconsin, Madison.

Over the years, the Wisconsin Longitudinal Study has been supported by several government agencies and by private foundations, as well as by the University of Wisconsin.

Since the early 1990s, the WLS has been supported mainly by the National Institute on Aging, which is part of the National Institutes of Health and also by the Vilas Estate Trust, the National Science Foundation and the Spencer Foundation.


We're continuing with interviews through the Fall of 2012!

As of March 2012, we've talked to 8000 people.

Welcome to the website of the Wisconsin Longitudinal Study, one of the most extensive and successful studies ever conducted in the social sciences. We are preparing for the next round of interviews that will begin in the Spring of 2010 and continue through the Summer of 2012.  But instead of talking on the phone, we plan on talking to participants in person.  We will be meeting with the"graduates," that is the original class of 1957 participant, as well as to the "siblings," a randomly selected brother or sister of the graduate, all of whom we've talked to before.   Study members will receive a letter with more details in 2010 or 2011.

We sent out printed copies of our results from previous waves of the Wisconsin Longitudinal Study surveys. We will soon post an electronic version of our most recent report. In the meantime you can download copies of earlier reports below.
