The U.S. inflation rate by year is the percent change in prices from one year to the next, or year-over-year.  

The inflation rate responds to each phase of the business cycle. The first phase is expansion. That's when growth is positive, with healthy 2 percent inflation. As the economy expands beyond 3 percent growth, it creates asset bubbles. It creates the second phase, which is the peak. That's the month when expansion ends and contraction begins.

Inflation will rise to 3 percent or more.

The third phase is contraction, which is a recession. Inflation falls below 2 percent. During a recession, deflation becomes a threat. The inflation rate falls into negative territory. The fourth phase is the trough. That's the month when contraction ends and expansion begins. After that phase, inflation turns positive again. 

Inflation also responds to monetary policy enacted by the Federal Reserve. The Fed focuses on the core inflation rate because it excludes volatile gas and food prices. The Fed sets a target inflation rate of two percent. If the core rate rises much above that, the Fed will execute contractionary monetary policy. This increases interest rates, shutting down demand and forcing prices lower.
