Many areas of urban dynamics research such as energy, water, climate, transportation, and health are closely linked to the demographic characteristics and behaviors of populations. The majority of detailed demographic information, such as joint sex by race by age counts, are reported at an aggregated Census tract level, but are often desired at finer spatial resolutions such as Census block groups, blocks, households, or even individuals. The absence of data that is both demographically and spatially detailed is a substantial obstacle in advancing urban dynamics research. To address this data gap, Oak Ridge National Laboratory (ORNL) has developed the UrbanPop Population Model and Database, which produces high-resolution and demographically detailed synthetic populations and summary data sets for all Census block groups within all 50 United States (US) states, excluding Wyoming. This presentation will discuss computational and theoretical improvements to the UrbanPop Population Model, as well as notable features of the recently developed 2016 UrbanPop Basic Demographics Population Database. With over 20 unique demographic characteristics describing the age, race, sex, and educational attainment of each synthetic agent, as well as summary statistics for over 800 different joint demographic characteristics, the 2016 UrbanPop Basic Demographics Population Database provides a valuable resource to users working in a variety of application spaces.
