Description: The population data points were created by joining the 2017 Census block group data to the 2019 DC OTR CAMA data and then joining the 2015 Census LEHD commuter block data to the DC OTR CAMA data as well. Each CAMA point was given a per unit population value based on the number of units in each Census geography. The number of units and the population per unit values were multiplied to get the estimated population per point. The nighttime population values were derived from the 2017 Census block group data and the daytime population values were derived from the combination of the Census block group data and the Census LEHD data. The LEHD data provides the estimated number of commuters leaving and entering a Census block each day, which when combined with the Census population data gives a rough estimate of daytime population within a Census block.
