Research @ Census

Researcher Profiles

Just Launched and Growing: "Our Researchers"

  • "Our Researchers", a new Research @ Census feature, is a work in process
  • If you do not find the researchers or publications you seek, keep checking back
  • We will continue to add both research profiles and publications

Our researchers produce innovations that keep our economic and social statistics efficient and relevant. Census researchers engage in challenging and rewarding work in a wide variety of fields. Researchers present their findings in working papers, publications, and reports, and in contributions at professional meetings.
