2020 Census Block King County - Redistricting Data 2020

Published by City of Seattle ArcGIS Online | City of Seattle | Catalog Last Checked: July 29, 2025 at 01:24 PM | Dataset Last Updated: July 26, 2022
Census 2020 blocks in King County with selected P.L. 94-171 redistricting data.For more information about the P.L. 94-171 redistricting data, please visit the U.S. Census Bureau.  For a detailed description of the data included please see the 2020 Census State Redistricting Data Summary File. Important note:  The Census Bureau advises analysts to aggregate blocks together to form larger geographic units before using the 2020 Census data. Background: The Bureau used a new tool, called Differential Privacy, to inject statistical noise into the 2020 Census data in order to protect privacy. The resulting noise can cause substantial inaccuracy at the block level; combining data for blocks and other small geographies reduces the inaccuracy. For more information see Redistricting Data: What to Expect and When (census.gov), 2020 Census Data Products: Disclosure Avoidance Modernization.
