Following the end of World War II and the large adjustment as the economy adjusted from wartime to peacetime in 1945, the collection of many economic indicators, such as unemployment and
gross domestic product (GDP) became standardized. Expansions after World War II may be compared to each other much more easily than previous expansions because of these available data. The listed dates and durations are from the official chronology of the National Bureau of Economic Research. The
National Bureau of Economic Research dates expansions on a monthly basis. From the trough of the recession of 1945 to the
late-2000s recession, there have been eleven periods of expansion, lasting an average of fifty-nine months. Included during this period is the
post–World War II economic expansion through the
1973–75 recession, a period of
stagflation between 1974 and 1981, and the
Great Moderation from 1982 to the start of the
late-2000s recession. == See also ==
