Guinea-Bissau has experienced steady population growth over the past several decades. As of 2024, the country’s population is estimated to be around 2.1 million, up from approximately 1.2 million in 1990. This growth is driven by a relatively high birth rate, despite challenges such as political instability, limited economic opportunities, and periodic public health crises. The population is predominantly young, with a significant proportion under the age of 25, reflecting high fertility rates and improvements in child survival. However, migration, both internal and external, also influences population dynamics, as many seek better opportunities in urban areas or abroad. Overall, Guinea-Bissau’s population growth presents both opportunities and challenges for sustainable development and resource management.
