The Population Data page allows you to view the county census population and also update the population served by a PWS. The first section displayed when you access the Population Data page is the County Census Population section, which displays the census population for each county. CDC periodically uploads this data from the Census Bureau. You can sort the displayed list by county name or total county population by clicking on the column heading.
After viewing county census population, you can proceed to update the population served by a PWS by clicking the PWS Population Served link.
