Well-being and quality of life in Brussels: indicators, rankings and challenges

Life satisfaction

According to IBSA Focus No. 77, produced in collaboration with the Federal Planning Bureau based on the EU-SILC 2023 survey, Brussels residents rate their life satisfaction at an average of 7.5/10. This score matches Wallonia (7.5) but falls below Flanders (7.8).

Among Brussels residents, 15.5% rate their satisfaction at 9 or 10/10, compared to 19.1% nationally.

The main determinants identified by IBSA are:

• Health (physical and mental) — the most influential factor
• A decent standard of living and adequate material conditions
• Maintaining social relationships and participating in activities
• Suitable housing
• The ability to work

Income and poverty

The Social Barometer 2023 from the Observatory for Health and Social Affairs documents a contrasting socio-economic situation:

• AROPE rate (at risk of poverty or social exclusion): between 25% and 33% of the Brussels population, relatively stable
• The poorest 10% have less than EUR 985/month per person; the richest 10% exceed EUR 4,120/month — a wider gap than the national average
• The number of social integration income recipients increased by 58% over 10 years (over 45,000 people)
• Six children out of ten are eligible for supplementary family allowances; the rate reaches 80% in Saint-Josse-ten-Noode
• Daily disposable income after housing: from EUR 9 to EUR 100 per person depending on the decile

The quarterly IALC monitoring (Statbel) indicates subjective poverty of 29.4% in Brussels (people reporting difficulty making ends meet).

Health and life expectancy

Life expectancy

Life expectancy at birth in the Brussels-Capital Region is 82.15 years (2024), below Flanders (83.2) and above Wallonia (80.6). Intra-municipal disparities exist: IBSA Focus No. 76 (2025) analyses life expectancy at neighbourhood level.

Physical and mental health

The Sciensano Health Interview Survey 2023-2024 (7th wave, 3,000 participants in the Brussels-Capital Region) covers over 400 indicators across 6 modules: health and quality of life, health determinants, prevention, mental health, healthcare, and health and society.

Results published since September 2025 show that the risk of frailty among older people is highest in the Brussels Region, followed by Wallonia and Flanders.

The interactive HISIA tool allows data consultation by region.

Social relationships and loneliness

Statbel's quarterly IALC monitoring measures self-reported loneliness. In Brussels, the rate fell from 9.5% (Q3 2023) to 4.8% (Q3 2024), a significant decline.

IBSA identifies regular contact with family and friends, as well as participation in activities, as factors promoting higher life satisfaction.

Environment and living conditions

Air quality

The Brussels Environment 2024 annual report confirms continued improvement:

• NO₂: European standards met at all 13 reference stations; 2030 targets not yet achieved at traffic-influenced stations
• PM2.5: EU standards and 2030 targets met; WHO recommendations (5 µg/m³) not reached
• PM10: slight annual exceedance only at Molenbeek-Saint-Jean

Green spaces

• 25 m² of accessible green space per inhabitant (stable since 1981 despite 400 ha added, due to population growth)
• 78% of Brussels residents have a green space within 200 m; 22% do not have one nearby
• 7 municipalities fall below the 10 m²/inhabitant threshold
• Extreme variation: from 1 m²/inh. in Saint-Gilles to 314 m²/inh. in Watermael-Boitsfort

Noise

According to the State of the Environment 2024 (2019-2022 data), 55% of Brussels residents are exposed to aircraft noise causing significant disturbance, and 30% experience problematic road traffic noise.

Perceived safety

The Urban Audit 2023 perception survey (European Commission, 83 cities, 70,000+ interviews) shows that 12.6% of Brussels residents report having been assaulted or mugged in the previous 12 months.

The OECD ranks Brussels among the lowest-performing regions for safety within its regional well-being framework (11 dimensions, data updated Oct. 2025).

Employment

The OECD places Brussels among the bottom 10% of OECD regions for employment, with an unemployment rate of 11.8% (Q2 2022), compared to 3% in the Flemish Region.

The IBSA Panorama socio-économique 2025 details Brussels labour market trends across 15 themes.
