Federal Debt: Total Public Debt as Percent of Gross Domestic Product (GFDEGDQ188S) was first constructed by the Federal Reserve Bank of St. Louis in October 2012. It is calculated using Federal Government Debt: Total Public Debt (GFDEBTN) and Gross Domestic Product, 1 Decimal (GDP):
GFDEGDQ188S = ((GFDEBTN/1000)/GDP)*100
GFDEBTN/1000 transforms GFDEBTN from millions of dollars to billions of dollars.

The “Consumer Price Index for All Urban Consumers: All Items Less Food & Energy” is an aggregate of prices paid by urban consumers for a typical basket of goods, excluding food and energy. This measurement, known as “Core CPI,” is widely used by economists because food and energy have very volatile prices. The Bureau of Labor Statistics defines and measures the official CPI, and more information can be found here: https://www.bls.gov/cpi/questions-and-answers.htm or here: https://www.bls.gov/opub/hom/pdf/cpihom.pdf.
