Different professions are present in very different ways depending on the territory. Their mapping by employment area highlights quite a clear contrast between highly urban areas with a high concentration of managers and intellectual professions and other areas which are more agricultural, more industrial, or with more manual labourers. These specific local features are linked in part to the uneven distribution of industries and enterprises with employees in the region. These specific features have tended to increase over time, although working class areas become less and less a feature. Increasing specialisation and the geography of the area also reinforce the interdependence of local labour markets. Indeed the jobs on offer in a territory are not necessarily held by members of the working population living in the same region. Therefore, there may locally be a significant mismatch between labour supply and demand, mainly in dense urban areas. However, this mismatch does not translate into a higher proportion of job seekers where it is greatest.
