Differential Privacy and the 2020 Census


Alternative Text

The Census Bureau has initiated a new methodology, differential privacy, to protect data privacy and confidentiality. Under the law, the bureau is required to do an actual enumeration of all residents and keep all personally identifiable information confidential for 72 years. Even though there were tools and safeguards in place, the bureau detected a need to revamp their disclosure avoidance and data switching technique because of the advancement of technology, computers and data science.

This webinar will address some burning questions: What is differential privacy? How will this new methodology work? What effect will it have on census data? And what does it mean for redistricters?
