Disparities in COVID-19 risk exposure: Evidence from geolocation data

We examine the determinants of COVID-19 risk exposure in the context of the initial wave in New York City. In the first wave of the pandemic, out-of-home activity and household crowding were strongly associated with hospitalization at an individual level. After mass layoffs and shelter in place restrictions, out-of-home mobility decreased in importance for the risk of COVID-19 hospitalization, while the household crowding channel remained important. A larger share of individuals in crowded housing or with high measures of out-of-home mobility were Black, Hispanic, and lower-income-which contributed to disparities in disease risk. We conclude that structural socio-economic inequalities helped determine the cross-section of COVID-19 risk exposure in urban areas.
