Overview
St. Kitts and Nevis holds the #203 global population rank among all countries, reflecting its very small population size. Over the past decade, the nation has seen an average annual growth rate of -0.05%, indicating a slight contraction in population over the longer term. This stagnation is typical among small island developing states, where emigration and low birth rates often offset natural increase. The current 0.18% one-year growth rate suggests a minor uptick, but the overall trend remains nearly flat. As a high-income country in Latin America & Caribbean, the demographic profile of St. Kitts and Nevis aligns with that of other mature economies, where population stability or slow decline is common. Regional context: The Caribbean's small island states experience demographic challenges such as aging populations and outward migration, with St. Kitts and Nevis exemplifying these patterns through its near-zero growth.
