“Good IT is invisible,” says MPC IT Core director Fran Fabrizio. “You want the users to have the idea that it’s a magic black box.” Though the intent is for the technology behind IPUMS and the other MPC data tools to seem effortless, Fabrizio understands the extent of the human work goes that goes into producing good technology. Getting 2.6 terabytes of data out to users each week requires no small amount of technology behind it.

Updated variables in IPUMS CPS and IHIS ease discovery and research of same-sex and cohabiting couples
IPUMS has updated the family interrelationship variables in IPUMS CPS and the Integrated Health Interview Series (IHIS) to include same-sex and cohabiting couples. The updated variables dramatically reduce research barriers for those interested in this family and household context.
Learning from Data: From Systemization to Investigation
Benjamin Hartman is a 2016 Summer Diversity Fellow at the MPC. As part of his fellowship, he learned how to take unprocessed data to produce harmonized IPUMS-I data and documentation, make GIS maps, and conduct his own case study investigating the spatial dimensions of internal migration using the Cambodian census. Hartman worked with his colleagues in IPUMS International to create this blog post.
New Feature: Terra Populus Launches TerraScope

TerraPop recently launched TerraScope, a map-based portal for exploring the data in the TerraPop collection. The TerraPop collection includes census data from over 160 countries around the world, as well as environmental data describing land cover, land use, and climate. With such a broad range of data available, selecting a study area for which data are available to study a particular question or, conversely, determining the types of research questions that can be studied within an area of interest can be challenging.
A History of Data: Good People, Good Work
Bethel University Professor of History Diana L. Magnuson is documenting the growth of the Minnesota Population Center. Believing that preserving institutional memory is vital, the Center is supporting Magnuson’s work to capture oral histories of past and present MPC faculty and staff. This is the third in a three-part series of oral histories. This post features several senior research staff: Trent Alexander, Sarah Flood, Ron Goeken, Patricia Kelly Hall, Monty Hindman, and David Van Riper.
When Migration is Out of Reach: New MPC Research on International Climate Migration

Migration is a valuable adaptation strategy under certain conditions, but when the world’s poorest regions experience crop failures from drought or other climate events, international migration decreases. Why do climate events lead to increased migration in some places, but decreased migration in others?
A History of Data: Information Technology and the MPC
Bethel University Professor of History Diana L. Magnuson is documenting the growth of the Minnesota Population Center. Believing that preserving institutional memory is vital, the Center is supporting Magnuson’s work to capture oral histories of past and present MPC faculty and staff.
This is the second in a three-part series, with oral histories from the information technology (IT) side of the MPC. For over 16 years, the IT staff has collaborated with the MPC research staff to recode and disseminate data, develop specialized software, and make research more efficient. The “secret sauce of the MPC” is the longstanding synergistic collaboration between IT and research staff.
