Answering the question proposed by the title? Housing was the main driver of inflation from March 2025 to March 2026. There is some of my editing in this presentation.
Overall prices increased 3.3% over the previous year 2025. 1.5 percentage points of the increase can be attributed to price increases in Housing . . . or ~one-half of it. Said another way: As of March 2026, overall prices increased 3.3% over the previous year. Of this, 1.5 percentage points came from price increases in housing, or about one-half of it. Housing can be found on Line 371 (Excel spread sheet).
“Table 7. Consumer Price Index for All Urban Consumers (CPI-U): U.S. city average, by expenditure category, March 2026, 12-month analysis table.”
The basket of goods and services used to calculate the CPI includes more than 200 individual items, grouped into eight major categories. These categories are:
- apparel
- education and communication
- food and beverages
- housing
- medical care
- recreation
- transportation
- other goods and services
The eight categories have individual inflation rates contributing to the overall inflation rate. If prices decrease in a category, its inflation rate is negative and it brings the overall inflation rate down.
Explanation: What share of the CPI does each category have?
The weight assigned to each category reflects its relative importance in a typical household’s budget, determined based on surveys of more than 20,000 households and individuals. Housing, which includes shelter, utilities, and household operations, holds the largest share of the CPI. Transportation has the second-highest weight, while food and beverages are third. Transportation had a 0.82 percentage point contribution to the annual inflation rate in March 2026. Food and beverages had a 0.38 percentage point contribution.
How have prices changed over the last year?
Regardless of the importance of categories within the CPI? Reviewing the inflation rate of each category can provide an understanding of how much prices are increasing or decreasing.
The highest inflation rate among the eight categories was that of housing. Housing prices were 3.4% (Line 371 Table 7) higher in March 2026 than they were a year in March 2025.
During the same period, education and communication prices did not change.
