Throughout the book, I cite data from standard government sources:
BEA: Bureau of Economic Analysis (GDP, industry accounts)
BLS: Bureau of Labor Statistics (employment, wages)
Census: Census Bureau (business establishments, trade)
Fed: Federal Reserve (financial data, flow of funds)
Industry Classification
Industries are classified using the North American Industry Classification System (NAICS). See Appendix C for a reference guide.
Dollar Figures
Unless otherwise noted, dollar figures are nominal (not adjusted for inflation) and refer to the 2022-2023 period.
Firm Data
When discussing specific companies, data typically comes from SEC filings (10-K annual reports) for public companies, or from industry sources for private companies.

For a broad overview: Read Part I (Chapters 1-3) to understand the overall structure, then dip into specific sectors of interest.
