NAF Rev. 2
The indices are calculated by INSEE using data collected in the branch surveys by:
Industrial production indices track the monthly growth in activity in France in industry and construction; they track the variation in quantities produced by the secondary sector.
From month to month, the industrial manufacturing industry index (C1 to C5) is used as one of the four main macroeconomic indicators, along with prices, foreign trade and employment.
Annual growth of French industrial production can also be compared to that of the other main developed countries. Finally, the annual industrial production indices also provide a reference against which other performances can be compared.
Since the publication of January 2009, the industrial production index has covered the following activites in the Aggregated classification (NA) associated with NAF Rev. 2:
|C1||Agricultural and food industries|
|C2||Coking and refining|
|C3||Electric and electronic equipment, other machinery|
|C5||Other manufactured goods|
Some branches are not completely in full, and businesses with fewer than 10 employees are not covered.
The series published up to the December 2008 publication covered the following activities in the Summary economic classification (NES) of NAF Rev. 1:
|EB||Agricultural and food industries|
Some branches were not covered in full.
They are still available in the macroeconomic database but they are no longer updated.
Industrial production indices meet a national and European imperative. They cover European regulation on short-term statistics (CE "STS" ruling n°1165/98 of the Council of 19th May 1998, amended by CE regulation n°1158/2005 of the Council of 6th July 2005, then by CE regulation n°1893/2006 of the Council of 20th December 2006).
From January 2009 until 2013, the industrial production index (IPI) will be calculated in base and reference 100 in 2005 (previously base 100 in 2000). This index (rebased every five years) is a Laspeyres index of production volumes. The weighting, by 2005 raw value-added at base prices, is constant.
The products tracked best represent the activity of the whole industry and are found at all levels of the production process. The monthly variations in the indices are made easier to interpret thanks to the calculation of series that are seasonally adjusted and corrected for the effects of the calendar year.
