The CDHA assists researchers to create, document, and distribute public use microdata on health and aging for secondary analysis. Major research themes include: midlife development and aging; economics of population aging; inequalities in health and aging; international comparative studies of health and aging; and the investigation of linkages between social-demographic and biomedical research in population aging. The CDHA is one of fourteen demography centers on aging sponsored by the National Institute on Aging.
Six major projects associated with CDHA are the Wisconsin Longitudinal Survey (WLS), the Mexican Health and Aging Study (MHAS), the National Survey of Families and Households (NSFH), the Puerto Rican Elderly Health Conditions (PREHCO), Health, Wellbeing and Aging in Latin America and the Caribbean (SABE), and Wisconsin Assets and Income Studies (WAIS). CDHA also provides support for new faculty development and for faculty, staff, and research assistants engaged in innovative pilot projects that are likely to lead to major NIA support. In addition, CDHA supports Latin American Mortality Database (LAMBdA).
