In preparing its monthly CPI reports, Statistics Centre - Abu Dhabi follows the methodologies adopted internationally in this field, using a broad and highly representative basket of goods and service, to ensure accuracy in the calculation of the index, which is the sole officially authorized source for monitoring changes in prices and inflation in the Emirate of Abu Dhabi.
SCAD has recently developed the computing of the CPI so that it is compiled according to households' types and levels of welfare. As for the welfare level approach, the population is divided into five segments (quintiles) representing five levels of welfare, based on average per capita annual expenditure. Each quintile reflects the consumption pattern represented by that quintile.
In regard to the household type approach, the population is divided into three types of households as set out in the results of the Household Income and Expenditure Survey (2007-2008), namely, national, non-national and collective households.
To represent all regions of the Emirate, the selected sample of items included in the Consumer Price Index basket uses actual data from the 2007 household income and expenditure survey. The sample of outlets were selected in such a way as to represent points of purchase for a large base of consumers all over the Emirate of Abu Dhabi, taking into account the geographical distribution of sources within the emirate.
