Unit of measure used
  • Index
  • Percentage change on the same period of the previous year
  • Percentage change on the previous period.


  • Sampling
  • Sample size: About 9,000 outlets are chosen for the survey and, on average, about 63,000 prices are collected each month for nearly 2,000 different items.
  • Sampling techniques: The outlet selection has a clustered design; the sample is determined centrally and has developed over time based on gradual expansion. The Item selection is also specified centrally, based on information from producers, commodity boards, scanner data and market research.


  • Base period
    The national reference year is 2006=100.

    Geographic coverage
    The CPI covers expenditures on the Dutch territory and abroad of all Dutch resident households.

    Institutional coverage
    People living in institutional households are not covered in the index.

    Item coverage
    In general, the Netherlands CPI classification is on a COICOP basis, however two artificial divisions are added. COICOP division 13, including consumption based taxes and government services and COICOP division 14, including expenditure by Dutch residents abroad. Together, using the current 2009 relative importance values, these two artificial divisions represent nearly 8% of the overall CPI. Among the unrecorded items and activities: games of chance, costs for life insurance, costs for pension premiums, and Financial Intermediation Services Indirectly Measured, sales of illegal market goods and services for consumption.

    Population coverage
    The index covers all private households resident in the country.

    Key statistical concept
  • The index measures monthly changes in the general level of prices of goods and services bought for consumption on the Dutch territory and abroad by resident households.
  • Types of prices: Consumption expenditure is valued at purchasers' prices, which include trade and transportation margins and applicable taxes less subsidies on products. The prices of certain second-hand goods, e.g. used cars, are included in the index. Donations and savings are excluded.
  • Price collection methods: Price data are collected on a monthly basis. Approximately 81 percent of all prices are collected locally by interviewers visiting retail outlets throughout the Netherlands. Mail order outlets, Internet shopping, and market stalls are included as well.
  • Treatment of rentals for housing: Included.
  • Treatment of Owner-Occupied Housing: OOH is included in the index and valued as the estimated rentals that tenants would pay for similar accommodation.
  • Treatment of missing prices: Missing prices are normally replaced within 2 to 3 months. Missing prices are imputed using the bridged-overlap technique.
  • Treatment of quality changes: Quality differences between new and replaced products are handled using a variety of methods, including direct comparison (i.e., no adjustment to the price), proportional quantity adjustment for small changes in package size, option prices (frequently used for new cars and computers), and imputations using other observed price changes.
  • Introduction of new items: Genuinely new products (example: DVD players, coffee pads) are brought into the index each year, when they become significant in their market segment, usually but not always in connection with the base year revision.
  • Treatment of seasonal items: Seasonal items are treated by giving seasonal weights. Item weights are zero in out-of-season periods. When an item comes into season again, the new prices are compared to the prices last observed for the previous season to compute the item index.


  • Classification(s) used
    COICOP (Classification of Individual Consumption According to Purpose)

    Aggregation and consolidation
  • Elementary aggregates (EAs): Item price indices are computed as the ratio of current period average over that of the base year.
  • Index formula: A Laspeyres formula (fixed base 2006=100) is used to compute the aggregate indices. Weights are mainly derived from the 2006 household budget survey.


  • Weights
  • Source of weights: The main source for the CPI expenditure weights is the household consumption data from the national accounts produced by the CBS.
  • Time period of current weights: computation base year (2006).
  • Frequency of weights updates: Expenditure weights are subject to annual updating.


  • Seasonal adjustment
    Indices are not seasonal adjusted.

    Other comments
    From January 2012, Statistics Netherlands introduced a new method in the measurement of prices for airline tickets and package holidays. Further information is available at the following adress:

    Country: Netherlands Subject: Consumer Price Index > Harmonised prices

    NLD.CPHP.......
    Name of collection/source
    Harmonised Indices of Consumer Prices. HICP are largely based on national price collections for national CPI calculations.

    Direct source
    Eurostat

    Sampling
    The HICPs are based on samples sufficient to yield reliable and comparable results and take account of national product and price diversity and changing products and outlets. Since the relative importance of consumers' expenditure on each good or service varies from country to country, there is no uniform basket applying to all Member States.

    Base period
    The reference year is 2005.

    Geographic coverage
    The whole country is covered.

    Institutional coverage
    Private and institutional households are included. Special estimates are done for non-residents' expenditure in the economic territory of the country.

    Item coverage
  • The coverage of the HICPs is defined in terms of 'household final monetary consumption expenditure', by reference to the national accounts concept of the European System of Accounts (ESA 1995).
  • The indices cover all forms of household expenditure, net of reimbursements, subsidies and discounts.
  • Spending by foreign visitors including tourists and cross-border shoppers in the economic territory of the Member State is included.


  • Population coverage
    From January 2000, the total domestic population is covered: urban and rural, high and low income, living in private or institutional households.

    Key statistical concept
  • HICPs are monthly price indices designed for international comparison of consumer price inflation.
  • Calculating the HICP has been a gradual process. In the beginning, many items for which treatment varied significantly from one national consumer price index to another were omitted but these have gradually been incorporated. The main item not yet included is owner-occupied housing costs. Detailed information is given in Eurostat news releases of 5 March 1997 and 18 February 2000, available from the Eurostat website.
  • Treatment of Owner-Occupied Housing: OOH is not included.


  • Classification(s) used
    COICOP/HICP (Classification of Individual Consumption by Purpose Adapted to the Needs of Harmonized Indices of Consumer Prices)

    Aggregation and consolidation
  • The European Commission regulation permits the use of either the ratio of arithmetic mean prices or the ratio of geometric mean prices or of an alternative provided that fulfils comparability requirements.
  • HICPs are derived using an annual Laspeyres-type chain-index formula where the chain index is based on the December of the previous year.


  • Weights
    The weights used in the HICP may refer to a base year up to seven years in the past but annual adjustments must be made for significant changes in the pattern of expenses.
