The Personal and family income statistics operation calculates the income of people aged 18 or over resident in the Basque Country and produces figures such as gross per capita income or average personal income; it forms the base for knowledge of the distribution of individual and family wealth, using taxation data, linked to census variables of the population. The breakdown of income according to population strata such as sex, age or relation to productive activity (unemployed, employed or retired population) allows us to have a closer awareness of diverse groups.
