In this 2.5 hour workshop, you'll learn how use mapping and spatial analysis to work with and visualize 2020 Decennial Census data. The Demographic and Housing Characteristics (DHC) file, released on May 25, includes our first look at detailed age, sex, and household characteristics from the 2020 Census all the way down to the Census block. You'll use R along with tools like tidycensus, sf, and Leaflet to explore and communicate trends in the new data.

In the first hour, you'll learn how to use tidycensus to access linked demographic and geographic decennial Census data within R. You'll get up to speed with geospatial Census data management in R, and you'll learn how to make a variety of Census maps with tools like ggplot2 and Leaflet.

The second hour will cover spatial data analysis with the 2020 DHC data. Given that new privacy protections in the data increase uncertainty for small areas, the Census Bureau recommends aggregating small counts to improve reliability. You'll learn how to use spatial analysis tools to perform this aggregation in your Census data work, and you'll gain experience with R's powerful GIS toolkit to generate custom insights.

The last 30 minutes will be a live question-and-answer session where you can get advice on your projects or ask any R, Census, or tidycensus-related questions.
