CHAPTER VIII – PRICES
COLOMBO CONSUMERS'
PRICE
INDEX
The Colombo Consumers' Price Index measures changes in the cost of a
fixed basket of consumer commodities and services entering into the
pattern of working class household consumption in Colombo. The
formula used in the computation of the index (including group and
sub group indices) is Laspeyre's Price Index Formula. The year 1952
has been taken as the base year and the weights have been obtained
from the results of a Family Budget Survey carried out among Colombo
urban working class families in 1949 - 1950 by revaluing the
items at average 1952 prices.
The items included in the index are classified into 5 main groups, viz. Food ,
Fuel and Light , House Rent , Clothing and Miscellaneous for each of which , a
group index is calculated.
Prices of the various articles of consumption entering into the budget of an
average working class household are collected weekly, fortnightly or monthly by
investigators in the open market as well as in the co - operative stores. In the
case of most of the food items such as vegetables and condiment items, actual
Test Purchases are made in the principal markets. Prices of textiles are also
collected from C.W.E. as well as from private retailers.
The average of the 4 weeks
prices is taken as the applicable monthly price.
GREATER COLOMBO CONSUMERS’ PRICE INDEX
This index is computed in accordance with the survey of
Socio-Economic and Labour Force conducted by this department during
the period of April 1985 to March 1986 covering the monthly
expenditure of low income earner middle class families and low
income earner families in the Greater Colombo area on the basis of
weight age on first 40% of non food and food items.
The selected goods and services were categorized into eight as Food and
Beverages, liquor, tobacco, betel, and arecanut, housing, fuel and lighting,
clothes and footwear, personally used temporary goods, household & health,
transport & communications, miscellaneous (education, recreation and permanent
items).
Greater Colombo area consist of Colombo
Municipal Council, Dehiwala Mt. Lavinia Municipal Council, Kotte
Municipal Council, Kolonnawa Urban Council, Peliyagoda Urban
Council and Wattala-Mabola Urban Council were selected for the
computation of index and was based on calculations from January to
June 1989. Value of expenditure for the survey period was
re-examined from January to June 1989 and average expenditure per
month was computed. During the base period the expenditure per
housing unit for Rs. 2347.71 was considered as 100 and using the
Laspeyre’s Price Index Formula, Colombo Consumers’ Price Index was
computed for each month from July 1989.
SRI LANKA CONSUMERS’
PRICE INDEX(SLCPI)
The
Sri Lanka Consumers’ Price Index is based on the Household Income
and Expenditure Survey conducted by the Department in 12 monthly
rounds from 1st November, 1995 to 31st
October, 1996. The weights have been computed for food and non food
items of the lower 80% of the total household based on the
consumption expenditure at all island level considering the
classification of individual consumption by purpose. A period of
three years from January, 1995 to December, 1997 was taken as the
base period. The average household size was 4.3 while the average
monthly expenditure amounted to Rs. 4,785.96 per household in the
base period. Hence one index point value is equal to Rs.47.86
