Data Dictionary

Every dataset this book uses, documented in one place: the data provider, sample years and frequency, the build_data/ notebook that regenerates the file, and every page of the book that relies on it. Click any dataset in the tables below for its detail page.

Students access course data through the course Box folder linked from the course site — the repository and this site do not ship the data files themselves. These listings document where each dataset comes from and how it is rebuilt.
