Weekly Retail Prices - 2015

Sri Lanka SL
Abstract
The Colombo Consumers' Price Index (CCPI) which was introduced in 1952 by the Department of Census and Statistics and which is now published on the last working day of every month is the official index by which changes in price levels of consumer goods and services in Sri Lanka are measured. Since then the index has been used to date for very vital purposes
as described below. It is used for multi-purpose functions such as :
for conversion of total current values of national income up to fixed values,
policy making on monetary income and wages,
payment of salaries and wages,
providing social security facilities and analysis of economic and social activities.
Thus the government mechanism and the non-government organizations use this index as the vital official measurement unit in the fields of financial, revenue, salaries, wages and socio-economic policy making.

Data Processing

Cleaning Operations
CLEANING OPERATIONS
Usually the prices collected should fall within a range accepted by the Prices and Wages Division staff. If by chance, an abnormally high or a low price have been recorded, that price item will be discarded and not taken for computation purposes.

In a rare situation where the prices of a commodity have not been recorded due to a problem in the market, then the previous day's recording will be assumed for the respective price collection round.
Other Processing
For each item, prices are collected in three instances by market and the average price for dissemination purposes are computed from those.
