Answer

Gross Domestic Product "GDP" is the total monetary value of all the finished goods and services produced within a country's borders during a specific time period. The U.S. government collects and compiles economic data through the Bureau of Labor Statistics "BLS". Once the data is organized, it is used by the Bureau of Economic Analysis "BEA" which is part of the Department of Commerce, to estimate the GDP and the national income.

The Bureau of Economic Analysis', Industry Facts, provides industry specific data.
