    FAQs

    • Are these "biggest industries" always the largest employers in a state?
      +
      Not necessarily. While a big industry contributes significantly to GDP, it might not always be the largest employer. For example, some industries are capital-intensive (relying on machinery more than labor), while others like healthcare or retail might employ more people but have a smaller GDP share.
    • How does the U.S. Bureau of Economic Analysis (BEA) determine the biggest industry?
      +
      The BEA calculates the biggest industry based on its direct contribution to a state's Gross Domestic Product (GDP), which represents the total value of goods and services produced within that industry in the state.
    • Why is "Real Estate" often listed as the biggest industry in so many states?
      +
      The BEA includes the imputed rental value of owner-occupied homes (as if homeowners rent to themselves) within the real estate sector, significantly boosting its GDP contribution. It also includes actual rents, property taxes, and construction.
