Methodological note

Methodological aspects

Household Projections consist of a statistical operation by Idescat which provides information on the future evolution of the number and the size of households Household Projections derive from the Population Projections de Catalunya (base 2018) by sex, age and area of residence, to which certain conditions are applied in order to determine the household population distribution.

With regard to the time horizon for the Household Projections of Catalonia, data is provided for all the years within the period 2018-2048, while for the time horizon for the territorial projections (areas of the Territorial Plan, provinces, counties and Aran), the data is for the period 2018-2033.

The results of the Household Projections are provided according to four evolution scenarios: the first three scenarios (low, average and high) combine the three propensity hypotheses with the population derived from the average scenario of the Population Projections for Catalonia, while the fourth scenario (low population variable) combines the average propensity hypothesis with the low population variable scenario.

  • Low scenario: Low propensities and average population.
  • Average scenario: Average propensities and average population.
  • High scenario: High propensities and average population.
  • Low population variable scenario: Average propensities and low population.

The average scenario is considered to be the main, or reference, scenario. The low population variable scenario is particularly relevant in the case of an evolution of low population growth.

The date of reference for Household Projections is 1 January of each year.
