Montserrat, a British Overseas Territory, is a small island in the Leeward Islands chain, with a land mass of 39.5 square miles and a resident population of 4,649 persons (Intercensal Count 2018). Following the onset of volcanic eruptions in 1995, much of the resident population left the island, leaving a disproportionate number of elderly residents, many of whom are living with chronic conditions. The impact of that migration 24 years later, is a population profile in which: 49% are men and 51% are women; 63% are nationals and 37% are non-nationals; 19% are aged under 15 and 15% are aged over 65 years and 54% are economically active, of which 96% are employed.
