Jonathan Bearak joined the Guttmacher Institute in 2015 and is a social demographer with a specific interest in illuminating factors that contribute to inequality in sexual and reproductive health and rights. His research applies Bayesian modeling, spatial analysis and econometrics to the study of global and population health. Dr. Bearak leads new research bringing Bayesian methods to the estimation of the global incidence of unintended pregnancy and abortion. He also leads research investigating the complex relationship between women’s fertility intentions and earnings inequality and spatial disparities in access to reproductive health care in the United States. In addition, Dr. Bearak is developing statistical models to improve the estimation of contraceptive failure rates, to explain variation in rates across methods, population groups and time periods. Dr. Bearak received his Ph.D. in Sociology from New York University.
