The United States started calculating data on wages and earning in the early 1800s. However, it did not start collecting monthly survey data on unemployment until the 1940s. Why did the government become more consistent at tracking data in the 1940s?
I. Congress passed the Dual Mandate Law which required a more accurate measurement of the Unemployment Rate.
II. The Federal Reserve requested the government track the data more regularly so it could better meet the Dual Mandate Law.
III. The events of the Great Depression created a desire to better track data to try to avert recessions or depressions before they start by identifying unemployment problems early.
