Call for SDC Steering Committee Nominations: Nominate by Dec. 20

Posted on Updated on

Nominations are now open!

The Steering Committee consists of nine members, elected to represent the states and territories enrolled in the State Data Center Program. Three members’ terms end each year, and three members are elected (or re-elected). We have vacancies due to departures of long-serving members.

Nominate yourself, or someone else. We are looking for SDC network colleagues who are motivated to serve the data user community, partner with the Census Bureau, and represent our States’ interests in Census. Employees of SDC Coordinating Agencies and State Lead Agencies are all eligible.

New Steering Committee members will be chosen through a general election. (see below.) 

Those elected this winter will begin their terms in February. This will be an in-person meeting. The Census Bureau fully covers Committee Members’ travel expenses.

How to nominate.

A nomination must include a brief biography, and concise answers to the following:

  1. For the brief biography: Where does the nominee work? Any special professional interests? Relevant related professional or program roles?
  2. What special perspective or goals would the nominee bring as a Steering Committee member?
  3. What aspects of the SDC program do you value most?
  • If you are nominating yourself, please answer all questions.
  • If you are nominating someone else – with their permission – please answer questions 1 and 2.

Please e-mail complete nominations to Todd Graham ( by December 20, 2019.

The real story.

If you are elected to the Steering Committee, you are signing up for monthly Steering Committee conference calls, and an expectation of volunteered time on committee initiatives, webinars, and other small projects. Before nominating yourself, determine whether you have the time and job-flexibility to contribute. Steering Committee members need to work for organizations that support these time commitments. 

There are also three trips a year for in-person meetings. These trips are usually 3 days. The Census Bureau fully covers Committee Members’ transportation, hotel and expenses.

Upcoming election.

The Steering Committee election will be held after Christmas and during the first two weeks of January. Every State Lead Agency will have one ballot to cast.

Nomination directions are above. Additional details on Steering Committee eligibility, term, and election can be found in the SDC Steering Committee By Laws, section 4.

What does the SDC Steering Committee do?

The Steering Committee consists of nine members, elected to represent the 56 states and territories enrolled in the State Data Center Program.

Per SDC Steering Committee By Laws, section 2. the Steering Committee advises the Census Bureau on the administration of the State Data Center Program; assists the Census Bureau in supporting decennial censuses and other surveys and programs; works with the Census Bureau to plan and conduct the Annual Training Conference; and improves the flow of information and ideas among member agencies and between member agencies and the Census Bureau.

In plain language: We’re here to serve the data user community, partner with the Census Bureau, and represent our States’ interests in Census.

If you have any questions, please contact Todd Graham, Bob Coats, or any member of the Steering Committee.

New decennial census demonstration data with differential privacy treatment

Posted on Updated on

From US Census Bureau, Customer Liaison & Marketing Services Office:

In a new Research Matters blog, Balancing Privacy and Accuracy: New Opportunity for Disclosure Avoidance Analysis, we discuss the just-posted new 2010 Demonstration Data Products designed to help data users better understand the 2020 Census disclosure avoidance system (DAS) and its impact on data quality and privacy protection.

You can access the data via the new 2020 Census Data Products page on You can also get there by searching “2020 data products” from the home page.

Please note that the data are only released via the FTP and in summary file format. Data will not be released on As a data intermediary, you may be asked to provide or extract data in a different format. So we encourage you to take a look at the summary file format to become familiar with the data.

Data user feedback will help the Census Bureau’s senior leadership make informed decisions about the final structure of 2020 data products and the fine-tuning of the disclosure avoidance system. Because decennial census data are widely used in ways that go beyond the Census Bureau’s needs, we want to ensure that they are fit for as many data users’ needs as possible.  Feedback on the demonstration files should be sent to

Please note that there will be a live Webcast of a National Academy of Sciences Center for National Statistics (CNSTAT) workshop on this topic on December 11-12, 2019. We’ll post more information on our Web site closer to the date.

Frequently Asked Questions for the Demonstration Data Products can be found on the website.
