From 2016 to 2025 the straight-line trend is upward, about 6.65 a year. A straight line explains 95% of the movement over 10 observed years.

What this measures

Index of the prices of consumption goods and services, as compared to a certain reference period (2010=100).

Limitations: Consumer price indexes should be interpreted with caution. The definition of a household, the basket of goods, and the geographic (urban or rural) and income group coverage of consumer price surveys can vary widely by country. In addition, weights are derived from household expenditure surveys, which, for budgetary reasons, tend to be conducted infrequently in developing countries, impairing comparability over time. Although useful for measuring consumer price inflation within a country, consumer price indexes are of less value in comparing countries.
