AmericaInflation is the rate at which prices change. Lower inflation usually means prices are rising more slowly—not that they have returned to earlier levels.
Separate the level from the rate
Imagine a basket costing $100, then $110, then $112.20. The increases are 10% and 2%. Inflation slowed, but the basket still costs more. This invented arithmetic example illustrates the distinction; it is not a current CPI reading.
BLS explains the Consumer Price Index as a measure of price changes for a consumer basket. The index level and its percentage change are different numbers. Specify whether a percentage compares months, years, or another window.
A household is not the average basket
Your spending mix can differ from the measured average. Housing, food, energy, transport, and other categories can move differently. Read the category and definition before treating a headline rate as your personal cost-of-living change.
To understand purchasing power, compare income and costs over the same period. A pay increase and a price increase should not be compared using mismatched dates or inconsistent units.
Read the chart carefully
America’s Dashboard labels the reporting period and unit for each series. A monthly observation is not necessarily a month-over-month change; the displayed inflation series is calculated year over year. Its trend should be read on that basis.
When sharing a chart, keep its source, comparison window, and observation date attached. A single low reading does not erase the accumulated change in prices or show that every household’s budget improved.

Your next steps
- Identify whether the number is an index level or a change rate.
- Use the same period when comparing income and prices.
- Keep reporting dates, categories, and units attached to charts.

Common questions
What would falling prices be called?
A decrease in a broad price level is deflation; slower positive inflation is disinflation.
Can inflation fall while groceries still cost more?
Yes. Prices can keep rising at a slower rate.
