About this dataset

Context

The dataset tabulates the Belgium population by age cohorts (Children: Under 18 years; Working population: 18-64 years; Senior population: 65 years or more). It lists the population in each age cohort group along with its percentage relative to the total population of Belgium. The dataset can be utilized to understand the population distribution across children, working population and senior population for dependency ratio, housing requirements, ageing, migration patterns etc.

Key observations

The largest age group was 18 to 64 years with a poulation of 203 (62.27% of the total population). Source: U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates.

About this dataset

Context

The dataset tabulates the data for the Belgium, WI population pyramid, which represents the Belgium population distribution across age and gender, using estimates from the U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates. It lists the male and female population for each age group, along with the total population for those age groups. Higher numbers at the bottom of the table suggest population growth, whereas higher numbers at the top indicate declining birth rates. Furthermore, the dataset can be utilized to understand the youth dependency ratio, old-age dependency ratio, total dependency ratio, and potential support ratio.

Key observations

• Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Belgium, WI, is 19.6.
• Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Belgium, WI, is 38.0.
• Total dependency ratio for Belgium, WI is 57.6.
• Potential support ratio, which is the number of youth (working age population) per elderly, for Belgium, WI is 2.6.

In 2023, the population of Belgium numbered around 11.7 million. Most of these inhabitants lived in the Dutch-speaking Flemish Region, which was home to nearly half of Belgium’s population. The Walloon Region, broadly in line with the French-speaking part of Belgium, numbered roughly 3.68 million inhabitants, and another 1.24 million lived in Brussels and the surrounding areas (which are bilingual).  

 Population density by region 

Despite having the lowest number of inhabitants, the Brussels-Capital Region had the highest population density, at nearly 7,400 inhabitants per square kilometer in 2017. By comparison, this was less than 500 inhabitants in Flanders and just 214 in Wallonia.
