Beginning in 1834, an index of business activity by the Cleveland Trust Company provides data for comparison between recessions. Beginning in 1854, the National Bureau of Economic Research dates recession peaks and troughs to the month. However, a standardized index does not exist for the earliest recessions. In 1791, Congress chartered the First Bank of the United States to handle the country's financial needs.
