Upcoming Events

Multigenerational Longitudinal Panel Workshop

December 16, 2020 Free Online Workshop

IPUMS Multigenerational Longitudinal Panel Training Workshop

Wednesday, December 16   |  11:00 am - 3:30 pm CST


Join the IPUMS Multigenerational Longitudinal Panel (MLP) team for a half-day workshop on this new resource. IPUMS MLP has produced crosswalks to link individual records in full count historical census data between adjacent censuses from 1900 to 1940. This release includes more than 165 million linked records, and future releases will build on this work and extend chronological depth. 

In this workshop, we will:

  1. Introduce complete count data and the challenges and opportunities of census linkage.

  2. Explain the MLP linking strategy and machine learning algorithm.

  3. Demonstrate how to access the data and to link to complete count data, including tips on managing file size.

  4. Taking questions throughout the workshop, and saving dedicated time at the end to answer questions about linked census data from IPUMS.

Researchers who have downloaded cross-sectional IPUMS microdata will get the most out of the workshop, but you do not need to be familiar with linked census data. 

Register to join us.
