Analysts across industries rely on data from the United States Census Bureau in their work. In this course, students will learn how to work with Census tabular and spatial data in the R environment. The course focuses on the tidycensus package for acquiring data from the decennial US Census and American Community survey in a tidyverse-friendly format, and the tigris package for accessing Census geographic data within R. By the end of this course, students will be able to rapidly visualize and explore demographic data from the Census Bureau using ggplot2 and other tidyverse tools, and make maps of Census demographic data with only a few lines of R code.

Geography professor at TCU and spatial data science consultant
I work as a geography professor at TCU and as a spatial data science consultant. My research focuses on demographic change and migration in US cities and suburbs; demographic data visualization; and tools for open data science. I'm also the author of the tidycensus, tigris, and idbr R packages for working with US Census Bureau data.
