City of Seattle ArcGIS OnlineCensus 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.
