The unemployment rate measures the number of unemployed as a percentage of the labour force. It is based on the International Labour Organization (ILO) definition of unemployment, which excludes jobseekers that did any work during the month and covers those people who are looking for work and are available for work. The report contains data on both total joblessness and just mainland unemployment; the latter is regarded as the more significant.

The data report the number of unemployed persons (quarterly average) for metropolitan France and for metropolitan France plus overseas departments. The metropolitan measure is regarded as the more useful guide.

The data provide a comprehensive report on how many people are looking for jobs and the unemployment rate. These numbers are the best way to gauge the current state as well as the future direction of the economy.

Despite the delay in publication of these data, investors can sense the degree of tightness in the jobs market. If labour markets are tight, investors will be alert to possible inflationary pressures that could exist. If wage inflation threatens, it is a reasonable bet that interest rates will rise and bond and stock prices will fall.
