Figure 4.8 – Renaming the census tables for clarity

One of the most challenging aspects of working with census data is solved by the ability to create column headings that are clear and descriptive.

The data you will use is redistricting data from the 2020 decennial release. Census Reporter simplifies the task so that you can focus on learning how to write SQL queries but let me give you a quick overview.

The documentation for the decennial release can be found here: https://www2.census.gov/programs-surveys/decennial/2020/technical-documentation/complete-tech-docs/summary-file/2020Census_PL94_171Redistricting_NationalTechDoc.pdf.
