WSDOT - Population Centers

Per RCW 47.04.010, "population center" includes incorporated cities and towns, including their urban growth areas, and census-designated places in Washington State. The WSDOT Population Center dataset combines the WSDOT Incorporated City Limits dataset (May 2021) with the Office of Financial Management’s Census Designated Places (2020 Census) Dataset. Identification of Population Centers enables WSDOT to address the Complete Streets requirement under RCW 47.04.035 and to otherwise identify locations prioritized in the 2021 WSDOT Active Transportation Plan (ATP). WSDOT may also recognize other developed areas as exhibiting land use patterns consistent with the definition of population center, that are not currently captured by this data layer. This data layer assists WSDOT in prioritizing active transportation improvements in areas where people congregate and access destinations, and where travel distances between destinations align with typical distances travelled by users of pedestrian and bicycle modes. These areas are a priority because they serve the broadest range of users and potential users of the transportation system, including the very young, very old, and people with disabilities. In this dataset, each Population Center includes information for the “Place Name”, the “Place Type” (city/town, Urban Growth Area outside of city limits, or Census Designated Place), and whether or not the Population Center intersects a State Route (“yes” indicates that there is an intersection with a State Route, “no” indicates that there is no intersection.). The dataset will be updated as needed.
