To promote the study of trends in the demography, economics, health, and healthcare of the elderly.


CDEHA builds upon and integrates work across multiple disciplines at Stanford in population studies, health economics, economics of retirement and medical technology assessment; and across multiple disciplines including statistics, econometrics, epidemiology, population biology and demography

Program areas within CDEHA include health disparities; the economics of retirement and demographic change; international population studies; the effects of medical technology on costs, outcomes and well-being of the elderly; and longitudinal and cohort studies of medical care, costs, and health and economic outcomes in the United States and other countries. The center also encourages cross-disciplinary collaborations and recruits promising trainees and junior faculty to conduct research in this area.

Need for this research

The United States and many other nations are experiencing a rapid increase in their elderly populations, prompting questions about future healthcare needs, how to finance care, and the nature of retirement. To address these issues, CDEHA promotes the study of trends in demography, economics, health, and health care, and the effects of these trends on the well-being of the elderly.

Aims of the Center

  • Effects of medical technology on costs, health outcomes, physical and psychological well-being, and health care decisions of the elderly.
  • Longitudinal and cohort studies of medical care, costs, and health and economic outcomes of older populations, in the United States and other countries, with particular emphasis on economic and health interest in outcome disparities.
  • Application of demographic techniques, including biodemography, to understand changes in survival, health, and well-being among the elderly over time.
  • Promotion of research in the demography and economics of aging at Stanford and in collaborating institutions, including other demography centers.

Funding provided by
• National Institutes of Health
