2020 Data Users Webinar Series

Whether we’ll have a 2020 Data Users Conference this year is still up in the air due to COVID-19, but in the meantime we’ve created a webinar series that will take place throughout the rest of 2020. Below you can find information on the upcoming webinars, or watch a replays of the one that have already happened.

MAY 21 WEBINAR:

Differential Privacy and the 2020 Census

Nicholas Nagle, Ph.D., Associate Professor of Geography, University of Tennessee, Knoxville

2020 Census results are confidential, but what if today’s computing power could be harnessed to re-identify individuals who responded? That’s the challenge facing the Census Bureau and the proposed solution called differential privacy could potentially impact the accuracy of statistics it will report next July.

Differential privacy might seem like a wonky topic but we promise it’s very important. From what we know thus far, it could result in significant changes to the 2020 Census data products. The wide-ranging discussions include reducing the amount of data and the number of tables. Some questions include:

  • What if noise injected into 2020 Census data rendered certain geographies-like census blocks-statistically unreliable?
  • What if data about race, ethnicity, household size and other statistics were available only at higher levels of geography, such as block groups or tracts?
  • What if the population of cities and counties had a margin of error? Does this create a lottery for each city’s distribution of state-share tax revenues in Tennessee?
  • How can communities conduct post-census challenges-like Census Count Question Resolution and Special Census programs-when error is intentionally infused in the data?

We are fortunate to have Dr. Nagle from the Geography Department at the University of Tennessee, Knoxville, addressing these questions and more in the webinar next week. He sits on a National Academy of Sciences panel that advises the U.S. Census Bureau about differential privacy, and chairs a census geography subcommittee about the topic as well.

Dr. Nagle’s article published in the Conversation this spring is a good introduction to the subject and highlights one particular area of concern: state-shared revenue distribution to counties and municipalities.

JUNE 18 WEBINAR:

Microdata for All: Creating Custom Tables on data.census.gov

KaNin Reese, Chief of Dissemination Outreach, Center for Enterprise Dissemination, U.S. Census Bureau

Accessing Census microdata (individual survey responses) is challenging without special software or expertise. But MDAT, the new Census Bureau Microdata Access Tool, unlocks this incredibly powerful data in a new web-based interface. It enables you to extract custom tables and statistics that might not available through the standard tables provided on data.census.gov. If you are an analyst, researcher, grant-writer or planner, you won’t want to miss this session.
