French Guiana Population Pyramid 2100
French Guiana in 2100
United Nations projections (medium variant) put the population of French Guiana at 775,238 in 2100. Ten years before, in 2090, the projected population is 725,137 — 6.9% lower.
Half of the population would be younger than 39.9 years, with 18.6% children under 15 and 21.2% aged 65 or older. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
