Data plotted as a curve. Units are percentage change from a year ago. The grey bar indicates a period of Great Inflation, which began in January 1965 and ended in December 1982. In January 1965, the percentage change from a year ago in the consumer price index began to rise until it peaked in March 1980 at close to 15 percent. In 1983, the percentage change from a year ago settled back to pre-Great Inflation levels of 0 to 5 percent.
