Reading the numbers
- The index measures a basket of goods and services bought by urban consumers; it does not follow any one price, so a house, a car or a college year may have risen more or less.
- The yearly figure is the average of the 12 monthly values, so the value at a particular month of 1988 can differ a little: use the calculator for exact months.
- The October 2026 figure uses the latest month in the data (index 337.511).
