The Population projections provide a simulation of the population that would reside in Spain in the next years, broken down according to basic demographic characteristics, on the basis of the population estimate at 1 January of the current year. They meet the need for a current outlook of the possible future demographic reality which is updated to the most recent demographic evolution. In particular, the object is to simulate the effects of the demographic structure and the current demographic tendencies on the future population.

This information is provided every 2 years with a 50-year projected horizon for the national total and 15 years for Autonomous Communities and provinces, following basic demographic characteristics.

As from 2018, a collection of projected basic demographic indicators (birth, fertility, mortality, migration and growth indicators and structure of the resident population in the country) is incorporated, summarising the future evolution of demographic phenomena in Spain in the event that current demographic trends are maintained.
