Ansley Coale

Ansley Johnson Coale (November 14, 1917 – November 5, 2002), was one of America's foremost demographers. A native to Baltimore, Maryland, he earned his Bachelor of Arts in 1939, his Master of Arts in 1941, and (after a period of service in the Navy) his Ph.D. in 1947, all at Princeton University. A long-term director of the Office of Population Research at Princeton, Coale was especially influential for his work on the demographic transition and leadership of the European Fertility Project.

Coale, the William Church Osborne Professor of Public Affairs Emeritus and professor of economics emeritus at Princeton University, was a prolific author, publishing more than 125 books and articles on a wide variety of demographic topics. His "Growth and Structure of Human Populations" (1972) is considered an essential textbook for those interested in formal demography. He also trained and served as a mentor to many students who became leaders in the field.

Coale joined the faculty at Princeton in 1947, the same year he received his Ph.D. at the same site. He spent his entire academic career at the University's Office of Population Research, serving as director from 1959 to 1975. He was president of the Population Association of America in 1967–68 and president of the International Union for the Scientific Study of Population (IUSSP) from 1977 to 1981.

Coale's first major influential work was Population Growth and Economic Development in Low-Income Countries (1958), whom he co-wrote with Edgar Hoover. The results, which showed that slowing population growth could enhance economic development, had a major impact on public policy and set the research agenda in this field.

This study was followed by Regional Model Life Tables and Stable Populations (1966), whom he co-wrote with Paul Demeny. These model life tables both established new empirical regularities, and proved invaluable in the development of later techniques for estimating mortality and fertility in populations with inaccurate or incomplete data. Along with William Brass, Coale pioneered the development and use of these techniques, first explained in Methods of Estimating Basic Demographic Measures From Incomplete Data (1967, with Demeny) and in The Demography of Tropical Africa (1968, with other demographers).
