The unemployment rate is calculated as the ratio of the number of unemployed to the number of active persons (employed or unemployed). For the whole of France (excluding Mayotte), until 2014, additional data were required in the French overseas departments to estimate the number of unemployed and employed persons during the three quarters when there were no survey results. Administrative data were thus used to estimate sub-annual trends in unemployment and employment2. They remain mobilised today, pending a sufficient time lag for seasonal variation corrections to be estimated solely on the basis of data from the Continuous Employment survey.
In addition to the unemployment rate, the other indicators on the labour market concern the structure of the population (employment, unemployment, activity), the characteristics of employment (type of contract, working time), as well as situations close to unemployment (halo around unemployment). Currently, these indicators cover only the field of the metropolis.
All series are seasonally adjusted by the X13-ARIMA method applied in the JDemetra+ software.
