How US Inflation Has Changed Over 100 Years

Economists quantify inflation using a percentage, like 2% or 3%, which represents the average rate at which prices are rising. They rely on a tool called the Consumer Price Index (CPI) to calculate the percentage. The CPI tracks price changes for the same basket of goods and services, enabling us to understand how much the items we commonly purchase have become more expensive.
