PRESS RELEASE Our Ref: BD.50/156/01/117
Date: 06th March, 2024
PRODUCER PRICE INDICES FOR THE QUARTER ENDING DECEMBER 2023
Introduction The National Bureau of Statistics hereby releases the Producer Price Index (PPI) for the fourth quarter October-December of 2023. The Producer Price Index measures the average change over time in the prices received by selected domestic producers for the production of goods. A basket includes a list of selected commodities of goods that are being priced on quarterly basis. The producer prices collected as at 15th of the mid-month of every quarter that is; (Q1: January- March), (Q2: April-June), (Q3: July-September) and (Q4: October-December).
Weights and a Reference Period The index weights are based on gross output derived from the 2015 Annual Survey of Industrial Production (ASIP 2015). The Producer Price Index on this release reports the indices with reference to Fourth Quarter (October-December) of the year 2018 (2018Q4=100). It shows the producer price changes since December 2018 up to fourth quarter of 2023, the index has been linked back up to the first quarter of the year 2013 to show the trend of price movements on three major sub-sectors of industry (Mining, Manufacturing, and Utilities).
Classification Industrial Classification follows the International Standard Industrial Classification of All Economic Activities (ISIC) Rev.4.
Methodology In the process of deriving the structure and weights, a top-down approach was adopted to maximize the indirect representation of industries and items. The basket selected and base weights were calculated from Gross Output (GO) based on The Annual Survey of Industrial Production of 2015. During the process of weights calculation, establishments with a contribution of at least 80% of Gross Output were selected in each ISIC Rev.4 Group.
2 A sample of establishments for inclusion in the price survey was then selected using cut -off sampling procedures.
The first level of aggregation is the class 4-digit ISIC; the se indices are the un -weighted Elementary Aaggregates (EA) and are being compiled using the Jevons geometric mean aggregation formula which refers to the Geometric Mean of the price relatives . The Elementary Aggregates indices are then being progressively combined with higher levels within the index structure (i.e. Group 3-digit, 2-digit division and 1-digit Section levels of the ISIC, and then the all-groups levels) using the standard base-weighted Laspeyres formula.
