Methodological note
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 2024) 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 2024–2054, while for the time horizon for the territorial projections (areas of the Territorial Plan, provinces, counties and Aran), the data is for the period 2024–2049.
The results of the Household Projections are provided according to three evolution scenarios, which combine the three propensity hypotheses with the population derived from the average scenario of the Population Projections for Catalonia
- Low scenario: Low propensities and average population.
- Average scenario: Average propensities and average population.
- High scenario: High propensities and average population.
The average scenario is considered to be the main, or reference, scenario.
The date of reference for Household Projections is 1 January of each year.
