Method of data collection

Prices for food items are collected weekly, by agents, from retail outlets and from six markets in Dakar. Prices for other items are obtained during the second half of each month. Quotations relating to service items are obtained from official tariffs. No account is taken of sale prices.

Housing

Rent data for recent dwellings with two rooms are obtained from a large real-estate company.

Specification of varieties

The specifications describe the variety, quality, make, brand, unit, etc.

Substitution, quality change, etc.

If an item disappears from the market, its price is used for a maximum of three months. The item is then replaced by a similar item for which a fictitious base price is calculated.

Seasonal items

Seasonal fluctuations in the prices of certain items are taken into account by maintaining the closing prices of the preceding season during the off season.

Computation

The index is compiled according to the Laspeyres formula as a weighted arithmetic average with fixed base, using weights corresponding to 1960-61.
