2100Spain in 2100
United Nations projections (medium variant) put the population of Spain at 33,127,478 in 2100. That would be 4.7% less than in 2090 (34,774,237).
With a projected median age of 53.2 years, Spain would have a youth dependency ratio of 22.3 and an old-age dependency ratio of 69.6 per 100 people of working age. The narrow base of the pyramid marks a constrictive age structure: fertility below replacement level and a rising share of older people.
