Kimbrough has served as a referee for Economics of Education Review, Demography, Journal of Economic and Social Measurement, and Southern Economic Journal.

leveraging datasets to answer questions

At SPA, Kimbrough teaches “Telling Stories with IPUMS Data.” This course introduces students to multiple publicly available sources of survey microdata from Integrated Public Use Microdata Series (IPUMS) including the decennial Census, American Community Survey, Community Population Survey, and American Time Use Survey.

“Students will learn about the questions these datasets can be used to answer, as well as the issues researchers encounter in analysis with microdata,” said Kimbrough. “Students will gain experience performing their own analyses to tell stories about population dynamics, economic behavior, and time use.”
