Scope

The index is computed monthly and covers private households in 13 urban areas.

Official base

Mid-July 1983 - mid-July 1984 = 100.

Source of weights

The weights and selected items were derived from a household expenditure survey conducted from mid-March 1984 to mid-February 1985 among 1,161 private households in urban areas. The index is designed to cover all non-institutional private households residing in urban areas, except one-person households, households composed of more than ten persons, households whose total consumption expenditure was less than 450 rupees or more than 3,500 rupees, households which derived more than 50 per cent of the value of their consumption expenditure from home production or sources other than the market place. The index covers 13 urban areas.

Household consumption expenditure

Included is the total value of goods and services purchased, home-produced goods and received free and as part of wage income and consumed, including the rental value of owner-occupied dwellings and free housing. Excluded are direct taxes, gifts and contributions, insurance premiums, occupational expenses, consumer debts, lottery tickets, money losses, expenditure on weddings, litigation expenses, etc.

Method of data collection

Prices are collected from about 700 retail stores and establishments by personal visits.

Prices are collected each week for fresh fruit and vegetables, each fortnight for fresh fish, milk and milk products, etc., and each month for clothing, fuel, etc. Prices for all other items are collected each quarter, except for education fees, physicians' fees, electricity charges and water charges, which are priced once a year.

The prices used in the index are those that any member of the public would have to pay on the pricing day to purchase the specified item or service, including sales and excise taxes.

The investigators collect prices from retail outlets on the cash payment basis. If the goods are not available on the free market, the prevailing black-market price is collected.

Housing

Rent data are collected each year through the house rent survey which covers about 448 households. No account is taken of owner-occupied housing in the index.

Specification of varieties

A number of market surveys were conducted in each sample town, mainly to select outlets and specifications for pricing. Each of the priced items in each of the selected centres is described in specifications which give the size, weight, materials used, workmanship and other qualitative and quantitative features.

Substitution, quality change, etc.

If a specific item is not available on the market, an appropriate substitution is made and the index is adjusted for the change in quality.

Seasonal items

For seasonal items such as fresh fish, fruit and vegetables that are not available on the market during the off season, the last available prices are used to calculate the index until new prices are available.

Computation

The index is computed according to the Laspeyres formula as a weighted arithmetic average with fixed base, using weights corresponding to the base period.

To obtain the national urban index, the three regional indices are combined, using regional weights based on the total urban population of each region.

Other information

Separate indices are published for the three regions: Urban Consumer Price Index for Kathmandu, Urban Consumer Price Index for Hills, Urban consumer Price index for Terai.
