Weekly Retail Prices - 2005 - Sri Lanka

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.
