Sample questionnaires to be published : marchto december.

The published series are seasonally adjusted (CVS). Seasonality tests are carried out on all series. A series that initially has no seasonal character is presented as a CVS series with zero coefficients and is equal to the gross series. The effects are estimated using the X-13 ARIMA method under JDemetra+ (provided by Eurostat) at the level of aggregates specific to the NAF rev. 2 subclass survey (structural work, frames and roofs, installation work, finishing). CVS indices for senior positions are obtained directly, not by aggregating the CVS indices that compose them.
