Inflation - Denver-Aurora-Lakewood Consumer Price Index

#FFFFFF

For local governments, Article X, Section 20 (otherwise known as TABOR), defines inflation to mean the percentage change in the United States Bureau of Labor Statistics Consumer Price Index (CPI) for Denver-Boulder (now Denver-Aurora-Lakewood). The Bureau of Labor Statistics provides the Denver-Aurora-Lakewood CPI figure and two State Agencies provide forecasts that can be used for the local government budget process.

Using CPI for Budget Projections

The Bureau of Labor Statistics releases the Denver-Aurora-Lakewood CPI figure annually around the end of February. Local governments recognize the timing of its release makes it too late to use actual numbers for annual budget preparation which must be completed in December. Accordingly most local governments find it necessary to use current year forecasts which are made available quarterly through both the Governor's Office of State Planning and Budgeting (OSPB) and the Colorado Legislative Council.

Many local officials use the forecasts to calculate TABOR limitations. Doing so necessitates recalculation of limits after the release of the actual Denver-Aurora-Lakewood CPI number to compare amounts approved in the budget document and make amendments if necessary.

In January 2018, the Bureau of Labor Statistics introduced a new geographic area for the CPI. The local CPI changed from Denver-Boulder-Greeley to Denver-Aurora-Lakewood. The Bureau of Labor Statistics CPI provides more information, and past actual numbers for the calculation of the index.
