Population by age and gender

  • Flemish age pyramid has wide top and narrow base

    The population pyramid of the Flemish Region in 2019 shows the typical profile of an ageing population: a wide top and a narrow base. The 50-to-64-year-olds (born as  the baby boom generation) constitute an important part of the legally resident population. This is the case for both men and women. 


    There are slightly more women than men in the Flemish Region. In 2019, this was 102 women per 100 men. The difference between men and women is the most prominent among the elderly: among the over-65s there are 122 women per 100 men; among the over-80s there are 160 women per 100 men.  

  • The Flemish population is ageing: 1 in 5 is over 65

    Since the turn of the century, the share of the legally resident population aged 65 and over has risen from 16.7% in 2000 to 18.2% in 2010 and to 20.2% in 2019. The share of under-18s fell from 20.6% in 2000 to 19.4% in 2019. The share of the broad middle group between the ages of 18 and 64 also decreased: from 62.7% in 2000 to 60.4% in 2019.  

  • More than 1 out of 4 seaside residents is over 65

    In almost 9 out of 10 municipalities in the Flemish Region, the proportion of people aged 65 and over is between 18% and 22% in 2019. This share is the lowest in Vilvoorde and Machelen (less than 15%). The proportion of over-65s is higher than 25% in many coastal municipalities, with a peak in Koksijde (40%). Other municipalities such as Schilde (25%), Aartselaar (25%), Sint-Martens-Latem (26%) and Horebeke (27%) also have a large share of  over-65s among their population. This proportion is relatively limited in the large cities of Antwerp (16%) and Ghent (17%). 

  • Population ageing in Flanders in line with European trend

    The share of people over 65 years of age in the usually resident population in the Flemish Region in 2018 amounted to 20%. This is very close to the European Union average (19.7%). This share is lower in the Walloon Region (18.2%) and in the Brussels-Capital Region (13.1%). Within the EU countries the highest proportion is found in Italy (22.6%), the lowest in Ireland (13.8%).
