In the US, the PPI was known as the ''wholesale price index'', or WPI, up to 1978. The PPI is one of the oldest continuous systems of statistical data published by the [[Bureau of Labor Statistics]], as well as one of the oldest economic time series compiled by the [[Federal government of the United States|Federal Government]].<ref>{{cite book|title=BLS Handbook of Methods|chapter= Chapter 14 Producer Prices, Background |url=http://www.bls.gov/opub/hom/homch14_a.htm| archive-url=https://web.archive.org/web/20101213024233/http://www.bls.gov/opub/hom/homch14_a.htm |archive-date=2010-12-13 |url-status=dead }}</ref>  The origins of the index can be found in an 1891 [[U.S. Senate]] resolution authorizing the [[Senate Committee on Finance]] to investigate the effects of the tariff laws "upon the imports and exports, the growth, development, production, and prices of agricultural and manufactured articles at home and abroad".<ref>[http://www.bls.gov/ppi/ppicpippi.htm Senate Committee on Finance, Wholesale Prices, Wages, and Transportation, Senate Report No. 1394, "The Aldrich Report," Part I, 52nd Congress, 2d sess., March 3, 1893; and U.S. Department of Labor, Course of Wholesale Prices, 1890–1901, Bulletin No. 39, March 1902, pp. 205–09.]</ref>
