Guinea’s population rose to 15.1 m people in 2025.

Neither way is good in itself. A larger population brings more workers and more customers, and it also puts more pressure on schools, clinics, housing and food supply. Which effect dominates depends on whether jobs and services expand at the same pace. The latest figure is 15.1 million for 2025, up from 14.8 million a year earlier, a rise of 0.34 million or 2.3%. Since 2016 the series has climbed from 12.1 million to 15.1 million, so the latest reading is the highest in that span.

Why it matters. With 15.1 million people, Guinea needs places in schools, clinics and homes for a population that grew by 2.3% in a year. Firms have a larger pool of workers and a larger market, and households in work-poor areas face more competition for jobs. The state has to plan budgets for services and infrastructure around a population that has reached its highest level since 2016.
