In the effort to better protect U.S. citizens' identities, the Census Bureau has forsaken some accuracy with its 2020 Census data, The New York Times reports. Thousands of “census blocks,” the smallest geographic area the Census Bureau measures for population, may be entirely inaccurate. The 2020 Census relied on differential privacy for the first time to mask data, however, it produced “nonsensical” results, such as having listed a census block of 14 people living in the Chicago River.
