Annex: ECOICOPv2

This annex contains the ECOICOP v2 classification and other relevant information.

Explanation of the various tabs

Tabs with names starting with numbers 01, 02, 03, 04 and 05 are in Dutch (NL). Although tabs starting with 05, 06, 07 and 08 have Dutch names, their content is in Dutch as well as in English.

Tab 05-Indexreferentieperiode

This tab provides an overview for all COICOPs for which the index reference year 2025 could not be calculated and the alternative reference years used.

Tab 06-Lijst-Speciale-Aggregaten

This tab contains an overview of special aggregates published in the CPI and HICP index series 2025=100. Special aggregates are sums of certain divisions, groups, classes, subclasses and/or microclasses. For each special aggregate, it is indicated whether it is part of the monthly publication of the flash estimate. This is indicated with a “J” (yes) or a “N” (no).

Tab 07-SA-CPI-2025=100

This tab shows the composition of the special aggregates in the CPI series 2025=100. This subdivision of the special aggregates applies to the CPI from 2017 onwards. For each special aggregate, all ECOICOPv2 groups that are part of that special aggregate according to the classification are listed. However, some of these groups are not included in the calculation of the Dutch CPI, for example because the consumer expenditure of Dutch households for that category is very low.

Tab 08-SA-HICP-2025=100

This tab shows the composition of the special aggregates in the HICP series 2025=100. This subdivision of the special aggregates applies to the HICP from 2017 onwards. For each special aggregate, all ECOICOPv2 groups that are part of that special aggregate according to the classification are listed. However, some of these groups are not included in the calculation of the Dutch HICP, for example because the consumer expenditure of Dutch households for that category is very low.

Tab 09_EN_ECOICOPv2

This tab shows the ECOICOPv2 classification. Some groups are excluded from CPI and HICP observations in accordance with international agreements, such as narcotics and prostitution. Some expenditure categories that are not included in the HICP but are included in the CPI have been added to the overview; see the “Details” column for more information.

A number of classes and subclasses represent only a small amount of expenditure. These are not included in the CPI and HICP observations and will not be published. These classes and subclasses are identified by the letter “N” in column D for the year 2025 and in column E for 2026.

The ECOICOPv2 classification has a hierarchical structure, similar to a tree with increasingly finer branches. Some groups in this structure are further subdivided, others are not. Column F indicates whether a group is at the lowest level — i.e. whether there are no further subdivisions. This is indicated by a “Y” (yes) or a “N” (no).

A number of abbreviations are used in the names of the groups, in brackets:

(D) stands for durable goods
(ND) stands for non-durable goods
(S) stands for services
(SD) stands for semi-durable goods

Furthermore, the abbreviation “n.e.c.” means not elsewhere classified.

Tab 10_EN_ECOICOPtoECOICOPv2

This tab contains the “translation” of the ECOICOP groups to the new ECOICOPv2 groups. Columns A and B contain the ECOICOP numbers and names, and columns C and D contain the numbers and names of the new classification.

For example, you can see that the current group “Fresh or chilled fruit” (number 011610) is split into five different groups in the new classification: “Dates, figs and tropical fruits, fresh (ND)” (011610), “Citrus fruits, fresh (ND)” (011620), “Stone fruits and pome fruits, fresh (ND)” (011630), “Berries, fresh (ND)” (011640) and “Other fruits, fresh (ND)” (011650).

The same COICOP number can therefore have a different meaning in the new classification.

Tab 11_EN_ECOICOPv2ToECOICOP

This is the reverse version of the previous tab. It contains the “translation” of the new ECOICOPv2 groups into ECOICOP groups. Columns A and B contain the new ECOICOPv2 numbers and names, and columns C and D contain the numbers and names of the ECOICOP classification.

For example, you can see that the new group “Bread and bakery products (ND)” (number 011130) originates from two groups in the old classification: “Bread” (011130) and “Other bakery products” (011140).

The basis for tabs 05 and 06 is formed by the lowest publication ECOICOPv2 groups in 2025. There are 224 of these.

Tab 12-Unrevised-Indices

This tab shows the HICP indices prior to the revision of the HICP in 2025, expressed in reference year 2015 = 100. The revision will change the indices of a number of ECOICOP groups. For the ECOICOP groups that are subject to change, this tab shows the indices for both the HICP and the HICP-CT (constant taxes).
