In an initial phase the address data are standardised and enriched with the data from the Census Section and then crossed with the tables supplied by the INE containing the set of variables relating to Household Income in order to assign these variables to the processed databases.

The indicators used to enrich the databases are grouped into three data sets that provide information on: average income per person and household; the source of income, such as salary, pension, unemployment benefit, other benefits or other income, as well as information on individuals living in certain areas such as: average age of population, percentage of minors, percentage of over-65s, average household size, percentage of single-person households and total population.
