The CPI measures the average change over time in the prices of goods and services consumed by people for day-to-day living.

The construction of the CPI combines economic theory, sampling, and other statistical techniques using data from other surveys to produce a weighted measure of average price changes in the Nigerian economy.

The weighting occurs to capture the importance of the selected commodities in the entire index. The production of the CPI requires the skills of economists, statisticians, computer scientists, data collectors, and others.

Key in the construction of the price index is the selection of the market basket of goods and services.

Every month, 10,534 informants spread across the country provide price data for the computation of the CPI. The market items currently comprise of 740 goods and services regularly priced.

Next we use the Laspeyres formula to compute an aggregated index for each class (which has a multitude of commodities which have similar consumption purposes):

Here the sum of the product of weights (obtained from the expenditure survey) and relative prices for each item is divided by the sum of the weight of the items in that class, and the result multiplied by 100 gives the required index number.

This index number is still classified according to the urban or rural classification sector for each of the 36 states and the FCT. This yields 85 classes then 48 groups which are then reclassified into 12 Divisions to derive:

  1. The country composite index
  2. The Urban National index
  3. The Rural National index
  4. The Combined Urban and Rural State Composite index

The survey methodology generates 3774 all items indices for all states and the FCT.

This edition of the Statistical News contains the revised Consumer Price Index (CPI) based on Nigeria Living Standard Survey (NLSS) 2003/2004.

The consumption expenditure data were re-valued to November 2009, which is the base period for the revised CPI.

The May 2003 and September 1985 based indices are being continued using factors derived from the new CPI. These indices will yield the same price change for any commodity group contained in all the series.
