Cumulative inflation
About this indicator
Inflation, measured by the growth of the Consumer Price Index (CPI), captures changes over time in the prices of goods and services consumed by households. It reflects how the cost of living evolves and directly affects the real purchasing power of households’ incomes and their welfare.
Cumulative inflation since 2010 reflects the extent to which an economy’s prices have increased or decreased since that base year. By accounting for the compounded effect of changes over time, this indicator summarizes long-term changes in prices rather than short-term fluctuations.
Calculation method: Each value on this chart represents the total percentage change since 2010. It is calculated by taking the difference between the annual price average of the year shown and that of 2010, divided by the 2010 value.
