Data-Intensive Research Conference

The Data-Intensive Research Conference was held virtually on Tuesdays and Thursdays, July 20 - August 5, 2021.

Researchers now have access to full count individual-level microdata from the U.S. Census spanning 1850 to 2010. Never before have social scientists had access to population data of this size and scope. These data present extraordinary opportunities but also some challenges. Our goals for this annual event are to:

  • highlight research that leverages expansive data resources,
  • provide training opportunities for working with these data resources, and
  • connect scholars with one another and with data experts.

The 2021 Data-Intensive Research Conference was co-sponsored by the IPUMS Big Microdata Network & the University of Minnesota Life Course Center and the Network for Data-Intensive Research on Aging (NDIRA).

The recordings from the 2021 Data-Intensive Research Conference are available now until the end of September and are linked below; the full conference program is available for your reference. Please contact [email protected] with questions or inquiries about the conference.

IPUMS Multigenerational-Longitudinal Panel

Jonas Helgertz and Matt Nelson

Overview Recording

IPUMS MLP Linking Strategy Recording

How to Use the Data Recording

The IPUMS Multigenerational Longitudinal Panel (MLP) has produced crosswalks to link individual records in full count historical census data between adjacent censuses from 1900 to 1940. This workshop will introduce complete count data and the challenges and opportunities of census linkage, explain the MLP linking strategy and machine learning algorithm, and demonstrate how to access the data and to link to complete count data, including tips on managing file size. The workshop will include a dedicated time for questions from participants.

The 1940 Census Linked to Modern Surveys of Older Americans

Rob Warren

Watch the Recording

Learn about linking records from the Health and Retirement Surveys (HRS), the Panel Study of Income Dynamics (PSID), the Wisconsin Longitudinal Study (WLS), the National Social Life, Health, and Aging Project (NSHAP), and the National Health and Aging Trends Study (NHATS) to records from the 1940 US Census. The workshop will review what data are available in the 1940 census; how records were linked; how successful linkage efforts were; and how to obtain the linked data. Additionally, the workshop will highlight examples of innovative research using these data and include dedicated time for questions.

FSRDCs & Full Count Census Data

Katie R. Genadek and Rachelle Hill

Overview Recording

How to Apply Recording

Federal Statistical Research Data Centers (FSRDCs) allow qualified researchers to access restricted use microdata from a variety of statistical agencies, including contemporary full count U.S. census data, to address important research questions. This workshop, led by Census Bureau research staff, will provide an overview of data that can be linked to full count historical and contemporary census data. This will include a description of data that are available to link, the linking methods used, how to apply for access to FSRDC data, and dedicated time for questions from participants.
