Abstract
The proposed chapter documents the rise of genomic data in demography over the past twenty years. It will have three parts. The first part describes the three major ways in which demographers have used genomic data (epigenetic dependent variable; genetic independent variable with biomedical dependent variable; and genetic independent variable with socioeconomic dependent variable) and provides historical background for each. It explains how genomic data have been added to long-running demographic studies, such as the Health and Retirement Study and Add Health, and provides an accessible description of genome-wide association studies and polygenic scores. The second part summarizes the most important discoveries demographers have made using genomic data. The third part explores the controversies that have erupted around the use of genomic data in demography and presents several challenges that still face sociogenomics.
