Memo on 2020 Census Data Distortion
Differential privacy is a new mathematical procedure devised by the Census Bureau that will be applied to the 2020 Census data before it is released to enhance data privacy protection. Our analysis indicates that data accuracy at the sub-state level will be sacrificed as a result of this new approach to data release. This inaccuracy may lead to misallocation of funds, poor capacity for planning, substandard service provision, and a competitive disadvantage in economic and workforce development.
