Ukraine
Official title
Consumer Price Index.
Scope
The index is computed monthly and relates to the urban population
in Ukraine.
Official base
December of previous year = 100. The index is rebased annually.
Sources of weights
Weights are derived from the family expenditure survey conducted
annually. The survey covers 0.1% of the urban population and all
regions of the country. The households are selected with multi-stage
probability sampling.
As the base period of the index differs from the reference period
of the weights, the survey data (annual averages) are adjusted by
price changes in December over annual average.

Household consumption expenditure
Consumption expenditures for the purpose of the index comprises
all goods and services purchased for consumption by the index
population.
Sample selection
The survey covers all regions in the country. Outlet selection
is based on data obtained from family budget surveys and trade
statistics.
Method of data collection
Each month, prices for 425 goods and services are collected from
about 28,000 outlets in all regions. Prices are recorded between
Tuesday and Thursday, from the 1st through the 25th day of each
month. Black market prices, hire purchase and second-hand
prices are not taken into account in data collection.
All goods are priced in 9-10 outlets in regional centres and
cities and 5-6 outlets in district centres and towns; services
are priced in 7-8 outlets in regional centres and 4-5 outlets in
district centres and towns.
Housing
Rent component of the rent, water, fuel and power group index
covers rents for state owned houses and dwellings in cooperative
ownership. Data collection is carried out monthly.
Specification of varieties
The specifications of the items to be priced are broad. The
price collectors select the most representative brand of the
specified item in each of the outlets visited and write down
detailed description of the make, brand, volume, size.
Substitution, quality changes
If a variety of a given type or quality disappears from the
market it is replaced with a comparable variety. If there is no
variety of similar quality, that type is excluded from further
observation. When a new product appears on the market, it is
included in the data observation.
Seasonal items
Relative price of a seasonally unavailable item is imputed taking
into account price movements of the other items included in the
same sub-group.
Computation
The index is computed according to the Laspeyres formulae. Ratio
of average monthly prices is used to compute item indices.
Population and consumption weights are used to aggregate regional
indexes into national index. Annual averages are computed as
geometric mean of monthly data.
Other information
None.
