Ever tried to locate GDP statistics for years before 1929? If so, then you’ll be as thrilled as I was to discover Economic History Resources – What Was the GDP Then?. This project by Louis Johnston and Samuel Williamson is available on the open web. For any year, or range of years, between 1789 and 2003 one can display the Nominal or Real GDP, the GDP Deflator, or the Real or Nominal GDP per capita for the United States.
