What is CPI for the last 20 years?

The Consumer Price Index (CPI) measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. Over the last 20 years, CPI has shown a general upward trend, reflecting rising inflation rates, particularly noticeable in the last few years due to various economic factors, including supply chain issues and increased demand post-pandemic. For specific yearly CPI values, it's best to consult the U.S. Bureau of Labor Statistics or similar official sources for the most accurate and detailed data.
