  3. Cont. • CPI provides an estimate of the price change between any two periods. • The CPI follows the prices of a sample of items in 12 main categories of consumer spending—such as food, clothing, shelter, and medical service.

  7. Why Update the C P I? • Updating the CPI basket items, and their weights; represents the current consumption patterns made by Sudanese households. • The item’s weight is the share of total household expenditure on the item to total households’ expenditure on all items.

  8. Cont. • Used as deflator for GDP in Services Sectors for example : Education , Health …ect. • change the base year according to the GDP year using the formula : • GDP Current year • Changed CPI

  9. CPI basket • The last update of the Sudanese CPI basket items was in 2007 based on the HBS that conducted in 2007. The previous basket of the CPI was based on 1978.

  10. Weights • reflects contribution to total expenditures of households. • determines the impact that its price change will have on the overall index.

  11. CPI Calculation • Laspeyres formula is used for the calculation. • CPI basket consists of 663 items and the consumer basket consists of 944 items. cut of 0.005 • temporarily missing and seasonal items are treated by distributing their weights at the other items in the same expenditure group. • Prices for fruits, vegetables, fresh meat, and fish food are collected on a weekly basis .other items are collected once a month. • The base year is 2007 for all the 15 northern states. • CPI is compiled for each state and for Sudan at the levels: state/ urban, state/ rural, and state.

  12. CPI Structure • Step1: Data/ Prices entry process - geographic areas and geographic weights. ∑ PnQo ∑PoQo *100

  13. Cont. • Step2: Calculation of relative prices and new weights, by dividing the current price by base year price. In addition, the new weight is calculated by multiplying the relative price by the base year weight . • Step3: To compute the minor group level, new weights for sub-minor groups within the minor group are aggregated and divided by the base year weights . The same procedures are done to calculate the Index at the major group level and finally for the general Index.
