Harmonized Malaria Indicator Survey (MIS) Data Now in IPUMS DHS

by

By Miriam King, Senior Research Scientist

Malaria is a pressing global health problem, with nearly 250 million malaria cases in 2022, according to the World Health Organization. Approximately 95 percent of malaria deaths were in Africa, with three-quarters of those deaths to children under 5. Climate change is increasing the transmission of mosquito-borne diseases, such as malaria. When IPUMS DHS recently received supplemental funding to support research on Climate Change Effects on Health, adding data on malaria was a top priority. Specifically, IPUMS DHS chose to integrate data from the DHS Malaria Indicator Surveys (MIS).

MIS have been fielded in nearly 30 African countries during the twenty-first century. Developed under an international partnership coordinating efforts to fight malaria, MIS surveys include some standard DHS variables on topics such as demographics, fertility, and household characteristics. MIS questionnaires also include hundreds of questions related to malaria. People’s knowledge about malaria causes, symptoms, and prevention; use of bednets; diagnosis and treatment of malaria, especially for pregnant women and children; exposure to public health messaging; and diagnostic blood testing for malaria in children under 5 are among the topics covered.

IPUMS DHS users now have access to harmonized data from 38 MIS samples, with geographic coverage shown in Figure 1. We prioritized harmonizing responses to MIS questions that matched variables already in the IPUMS DHS database, for approximately 700 widely available variables.

“Celebrating 30 Years: Three Decades of IPUMS Data,” the current exhibit at ISRDI Headquarters, highlights thirty years of data innovation at the University of Minnesota. In the late 1980s, the Social History Research Laboratory at the University of Minnesota’s History Department proposed “the creation of a single integrated microdata series composed of public use samples for every year … with the exception of the 1890 census, which was destroyed by fire.” The primary aim was to make the U.S. census microdata “as compatible over time as possible while losing little, if any, of the detail in the original datasets.” (Integrated Public Use Microdata Series: A Prospectus).

Steven Ruggles remembers the moment he went into the History Department lounge on the sixth floor of the Social Science Tower and said, “IPUMS! Integrated Public Use Microdata Series! Isn’t that a great idea?” The response from the graduate research assistants was not enthusiastic. “What a terrible name! You can’t call it that!” According to Ruggles, “It was universal; everyone thought it was just a horrible name … It wasn’t a bad idea to propose, just a terrible thing to call it.” After a brief quandary over pronunciation (Ī-pŭms or Ĭ-pŭms), the name has stuck and is now synonymous with social research, data innovation, and free access. And for the record, we don’t care how you pronounce it, just as long as you cite it!
