Deming developed the sampling techniques that were used for the first time during the 1940 U.S. Census, formulating the Deming-Stephan algorithm for iterative proportional fitting in the process. During World War II, Deming was a member of the five-man Emergency Technical Committee. He worked with H.F. Dodge, A.G. Ashcroft, Leslie E. Simon, R.E. Wareham, and John Gaillard in the compilation of the American War Standards (American Standards Association Z1.1–3 published in 1942) and taught SPC techniques to workers engaged in wartime production. Statistical methods were widely applied during World War II, but faded into disuse a few years later in the face of huge overseas demand for American mass-produced products.
