  1 Beginning 4 February 2022, the base year of the Consumer Price Index (CPI) was updated from 2012 to 2018. The rebasing of the CPI is done periodically by PSA: (1) to ensure that the CPI market basket continues to capture goods and services commonly purchased by households over time; (2) to update expenditure patterns of households; and (3) to synchronize its base year with 2018 base year of the Gross Domestic Product and other indices produced by PSA.
