Portugal

The segmentation concerned the approximately 177,893 sections in which the Portuguese territory was divided during the 2001 Census. Based on the socio-economic data collected, the sections were classified, with statistical procedures, in 11 groups. Each section, containing on average about 21 families, therefore belongs to a single group identified on the basis of its main characteristics.
In the following descriptions we refer to the average characteristics of each group and therefore to the average of thousands of sections.
When we speak of "maximum value" or "minimum value" we mean the highest, or lowest, value that occurs in the average values of groups A to L, excluding therefore the special areas (group S) that represent a share negligible population.
When we talk about the "presence" of a Group we refer to the absolute values of its population, while when we speak of "concentration" we mean its relative share (percentage) with respect to the total population of the area to which it refers.
