Kathryn Kost, Senior Research Associate
Kathryn Kost began working with Guttmacher Institute more than 20 years ago, as a Senior Research Associate from 1989 to 1998. She worked as a consultant to the research division from 2004 to 2009 and returned to the Senior Research Associate position in late 2009. Dr. Kost’s research for the Institute has addressed a range of topics crucial for understanding reproductive behaviors and trends in the United States, including patterns of sexual behavior, characteristics of abortion patients, health consequences of unintended pregnancy and estimates of contraceptive failure. Most recently, Dr. Kost worked on studies of U.S. trends in abortion rates and of teen pregnancy rates over the past 30 years. Dr. Kost received her B.A. in sociology from Reed College in 1982 and a Ph.D. in sociology from Princeton University in 1990, where she specialized in demography at the Office of Population Research.
