Volume indices

Nominal GDP values in a national currency (at current prices) are spatially deflated into Real GDP values with the aid of purchasing power parities (PPPs) and converted into a common currency (in EU comparisons referred to as purchasing power standard or PPS). To increase their transparency, these GDP values in real terms are presented in the form of index numbers (base country/group = 100) and provide information about the total volume of a particular country measured against that of the selected base country (country or group of countries).

GDP per capita in PPS (= to PPPs)

Per-capita volume indices depict the volume of GDP per inhabitant in real terms in relation to the base country/group of countries (e.g. EU-27 = 100) and are interpreted as a measure of the relative level of development of a national economy.

As for comparative price levels, it is not advisable to draw up stringent country rankings. Instead, country clusters with a similar level of development should be created.

Volume indices – data

As a member of the European Union, Austria – through Statistics Austria – participates in the European Comparison Programme (ECP), in which Eurostat collaborates closely with the OECD. As a result, the regular publication of PPP-based data and thus of up-to-date tables concerning volume indices is the responsibility of these international organisations. An overview of currently available data is provided below:

  1. EUROSTAT
    1. GDP per capita in PPS (EU-27_2020 = 100) Structural indicator
