Overview
Guatemala, classified as an upper middle income country in the Latin America & Caribbean region, has a population that continues to expand at a moderate pace. The latest 2025 figure of 18,406,359 reflects a 1-year growth rate of 1.55%, which is slightly below the 10-year average of 1.61%, indicating a gradual slowdown in population increase. This demographic trend aligns with broader regional patterns where many Latin American nations are experiencing declining fertility rates, though Guatemala's growth remains relatively high compared to neighboring countries like El Salvador or Costa Rica.
The country's population dynamics are shaped by a relatively young age structure, with a significant proportion of the population under 25, contributing to sustained growth. Urbanization is ongoing, with a growing concentration in the capital, Guatemala City, and other departmental capitals. Despite being an upper middle income economy, Guatemala faces challenges in infrastructure, education, and healthcare to accommodate its expanding population.
Regionally, Guatemala's population accounts for a substantial share of Central America's total inhabitants, reinforcing its role as a demographic and economic hub. The 10-year average growth rate of 1.61% suggests consistent expansion over the past decade, driven by both natural increase and relatively high birth rates compared to other upper middle income countries. However, emigration to the United States and other destinations has historically moderated net population growth.
Looking ahead, Guatemala's population is projected to continue growing, albeit at a decelerating rate, as fertility declines and life expectancy improves. The country's global rank of #69 underscores its medium-large population size on the world stage, positioning it as a key player in Central American affairs.
