Overview
Guinea-Bissau is a small West African nation with a population that has been growing steadily. The latest one-year growth rate stands at 2.23%, while the average annual growth over the past decade is slightly higher at 2.37%. This sustained growth reflects high fertility rates and a relatively young age structure, common in many low-income Sub-Saharan African countries. The population of 2.2 million is concentrated in coastal areas and the capital, Bissau, with rural regions also experiencing demographic expansion.
In the regional context, Guinea-Bissau is part of Sub-Saharan Africa, a region characterized by rapid population growth and urbanization challenges. The country's low-income status means that infrastructure, healthcare, and education systems face pressure from the increasing population. Despite the growth, Guinea-Bissau remains one of the least populous nations in West Africa, with a population density that is moderate compared to neighbors like Senegal or Guinea.
The 10-year average growth rate of 2.37% indicates that the population has been expanding at a consistent pace, though slightly decelerating in the most recent year. This trend aligns with broader demographic transitions in the region, where declining mortality rates have not yet been matched by significant fertility declines. The global rank of #147 underscores that Guinea-Bissau is a relatively small country in terms of population, but its growth rate is above the world average.
Looking ahead, continued high growth will likely keep Guinea-Bissau among the faster-growing populations globally. Economic development, family planning access, and education will be key factors that could influence future demographic trends. The data provided does not include age distribution or urban-rural splits, but the overall growth pattern is typical for a low-income Sub-Saharan African country.
