Q. What was the cost of living in the United States during certain years in the past?

This information can be found via the SCU Library's reference series called "The value of a dollar : prices and incomes in the United States."

Additional information on specific prices can be found via the University of Missouri's website "Prices and Wages by Decade" which links to government documents and primary sources listing retail prices for products and services, as well as wages for common occupations.
