Belgium Population Pyramid 2024
Belgium in 2024
As of 2024, Belgium counted 11,738,764 inhabitants. A decade earlier, in 2014, the population was 11,210,119; it has grown by 4.7% since.
Half of the population was younger than 42.7 years; 16.0% were children under 15 and 20.6% were 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
