Regional GDP and regional value added from 2000 to 2023 Regional accounts (2020 base)

Regional gross domestic products and regional added values by industry are available in 2020 baseline for the period 2000-2023. 2023 estimates are provisional at this stage. Provisional estimates rely on the same methodology as a semi-final or final accounts. For more information, refer to the documentation. This publication is the first in 2020 baseline.

Regional gross domestic product (GDP) is calculated on a 2020 baseline in line with national accounts and in accordance with the European System of Accounts 2010 (ESA2010).

Regional accounts are consistent with the annual national accounts. Publisehd data corresponds to the national accounts field, namely metropolitan France, overseas regions (Guadeloupe including Saint-Martin, Martinique, Guyane, Réunion, Mayotte) as well as the extra-regional territory (embassies, military or scientific bases...).

At a regional level, overseas regions are the only regions that have a complete accounts system. They are implemented by the INSEE services in the overseas regions, according to their own methodology. The regional economic indicators of metropolitan regions (GDP and added values) result from a regionalization of metropolitan indicators based on distribution keys.

Metropolitan GDP and added values of each industry are equal to the difference between the total for all of France (established at the beginning of May each year) and the following total: the data for the 5 overseas + extra-regional territory.

The regional data are thus consistent with national data.

Determination of regional added values at current prices in a first phase...

For the metropolitan regions, the estimates of regional added values of the market industries (excluding agriculture and finance) are based on the FARE file and employment and compensations data. FARE comes from the ESANE process. Employment and compensations data come from the FLORES file, except for the provisionnal estimates which rely on HERACLES. These sources make it possible to locate all economic activity (ESANE) through the number of employees and salaries of establishments in employment files. The FARE file (Esane source), which contains the main variables of the business accounts, gives the value added of each company in the sense of a legal unit; this value added is then regionalized pro rata to the payroll of each establishment (present in the employment source (FLORES or HERACLES). The values added of the establishments are then aggregated by sector and region. In order to be consistent with the national accounts, the sum of the regional values added for each industry is based on the metropolitan value added from the national accounts.

For the sake of simplification, establishments main activity is assimilated to industry.

The work is carried out by crossing industries (A17 NACE-level) and regions.

Non-market industries (and the non-market part of mainly non-market industries such as health and education) as well as agriculture, financial and insurance activities and imputed rental are subject to specific treatment; the method described above cannot be applied because the Esane source does not cover these activity fields.

Agriculture value added’s regionalisation relies on indicators established by the Ministry of Agriculture (ex: breakdown from available production data by department). Up to 2023, imputed rental (rents that owner-occupiers would pay to themselves) were regionalized using the rental values provided by fiscal administration. In the new 2020 baseline, imputed rentals are broken down according to the building tax contained in the REI file built by the fiscal administration. Similarly, from 2021 onwards, the value added of the TZ branch (individual employers) is broken down according to the local wage masses provided by ACOSS. Previously, the breakdown was based on local employment data provided by the Direction for Demographic and Social Statistics of INSEE. For the other non-market branches, metropolitan added values are regionalized on a pro rata basis of gross earnings of FLORES/HERACLES.

...then regional GDP of the metropolitan regions at current prices

The regional structure of the value added of the metropolitan regions in value previsouly obtained is applied to the GDP of the metropolitan regions at current prices (national GDP less the overseas regions GDP, minus the extra-regional territory) to deduct the GDP of metropolitan regions at current prices in this field.

... and regional gross domestic products “in volume” (i.e. “in volume” chained from base 2020)

Metropolitan regions GDP in volume terms are obtained by using regional value added as distribution key. The structure is applied to the national GDP figure in volume terms, minus overseas regions GDP in volume terms, minus extra-regional territory GDP. These estimates should be used with caution because they are not derived from the calculation of a regional price index.
