United Nations projections (medium variant) put the population of Saint Lucia at 108,207 in 2100. That would be 9.6% less than in 2090 (119,729).
The median age is projected at 52.0 years, with 21.8 children under 15 and 60.6 people aged 65 or over for every 100 people of working age (15–64). This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
