Differential Privacy Demo

CTData Collaborative

To protect the confidentiality of 2020 Census respondents, the US Census Bureau plans to use a "differential privacy" framework. It is a statistical technique to protect individual data from reidentification or reconstruction. To help data users assess the impacts of differential privacy, the Census Bureau has shared files that show the impact of differential privacy on 2010 decennial data.
