Economic Definition of disinflation. Defined.

Term disinflation Definition: A decline in the inflation rate. With disinflation, prices are still rising, they're just not rising as fast. Numerically speaking, if the inflation rate was 10% last year, 6% this year, and looks to be 4% next year, then we have disinflation. Disinflation, a reduction in the inflation rate, is not the same as deflation, a decline in the price level. Prices continue to rise with disinflation, just not as fast. Should disinflation continue, presumably because anti-inflationary monetary or fiscal policies are working effectively, then the average price level could decline and we make the transition to deflation.
