What is the source of data that the calculator uses?
This program uses inflation data from several sources, including Global Financial Data, Economic History Services, the U.S. Bureau of Labor Statistics, the Congressional Budget Office, and ShadowStats. The most widely quoted inflation rate is the U.S. government’s Consumer Price Index (CPI), 1914 to present, as compiled by the U.S. Bureau of Labor Statistics. By default, my Inflation Calculator uses the CPI-U data (CPI for All Urban Consumers), not seasonally adjusted (data series CUUR0000SA0). Data before 1914 was mostly reconstructed by economists from old records and is less reliable. The CPI-W data (CPI for Urban Wage Earners and Clerical Workers) is also from the U.S. Bureau of Labor Statistics, 1914 to present (data series CWUR0000SA0). The medical-cost data is a subset of the government’s CPI but has been tracked only since 1936 (data series CUUR0000SAM). The CPI-U December-to-December retail inflation is also from the U.S. Bureau of Labor Statistics and extends from 1914 to pre
