Midlife in the United States (MIDUS)

Established in 1995, the Midlife in the United States (MIDUS) study "was conceived by scientists from diverse fields who were interested in how physical and mental health changes across the decades of adult life, for whom, and why. To probe these questions, they surveyed over 7,000 Americans aged 25-74, asking for detailed information about people’s work and family lives as well as their views of themselves, their worries and concerns. [...] In 2002, the National Institute on Aging funded a second assessment of the original participants (MIDUS 2), thus transforming MIDUS into a longitudinal study. Based out of the University of Wisconsin-Madison, 75% of the original respondents were re-interviewed. The study was also expanded to include a battery of biological risk factors as well as neuroscience measures on subsets of respondents. A sample of 600 African Americans from Milwaukee, WI was also added to MIDUS 2 to sharpen the focus on the health and well-being of American minorities." (http://midus.wisc.edu/puboverview.php)
