Household consumption expenditure
Consumption expenditure for the purpose of establishing the
weights includes all goods and services purchased by the index
population for their own use. It excludes income taxes,
statutory contributions, investment expenditures and all
insurance.
Consumption expenditure excludes: pension fund contributions,
owner-occupied housing (only rented housing is included), the
trade-in value of used goods, down-payments on the purchase of
new goods, trading licences, fund transfers, gifts and other
transfers, all taxes and insurance.
It includes: income in kind, second-hand purchases, durable
goods, medical care, credit purchases (limited to disbursements
made during the survey period).
Method of data collection
Prices are collected from about 34 selected retail stores,
markets and service establishments by personal visits. Prices
for food items such as starchy foods, fish, vegetables, fruit and
some clothing items are obtained four times a week and for other
items once a week. Prices for food items sold in market places
are ascertained by weighing the items.
Housing
Rent data are obtained from selected rented dwellings with two
rooms, a concrete floor and electricity. For owner-occupied
dwellings, only the cost of repairs and maintenance is included
in the index.
Specification of varieties
The specifications of items to be priced are given in detail in
terms of the brand, quality, make and unit.
Substitution, quality change, etc.
If a product is no longer available in the outlet, a similar
product to the original is substituted.
Seasonal items
Seasonal items such as fresh fruit and vegetables are not
significant in the index, and no special treatment is therefore
given for seasonal items.
Computation
The index is computed according to the Laspeyres formula as a
weighted arithmetic average with fixed base, using weights
corresponding to the period 1978-79.
Relatives of average prices are used to calculate item indices.
Annual indices are the averages of the 12 monthly indices
Other information
A survey is currently being conducted in Bujumbura for the purpose of
updating the base for computing the consumer price index.
