Brussels and Jakarta sit in different leagues for relocating families. Brussels is EU institutional life with subsidised European Schools and a tight ISB/BSB premium tier. Jakarta is tropical Asian living with two world-class IB and British anchors at JIS and BSJ. Both serve the IB Diploma at the senior end, which keeps university choice open in the UK, US and Asia.
Schools landscape side by side
Brussels's international school market is anchored by International School of Brussels (ISB), British School of Brussels (BSB), St John's International School, European Schools Brussels I to IV. Brussels has the unusual luxury of the official European Schools system serving EU staff at low or no cost, alongside ISB (full IB continuum), BSB (A Level, IB Diploma, BTEC) and a strong French and German lycee network. See the Brussels schools hub for a deeper read on each campus.
Jakarta's flagship international schools include Jakarta Intercultural School (JIS), British School Jakarta (BSJ), Australian Independent School (AIS), Sekolah Pelita Harapan (SPH). Jakarta's market splits between IB continuum giants JIS and Sekolah Pelita Harapan, British schools BSJ and BIS, and a wide National Plus mid-tier blending Indonesian curriculum with English instruction. See the Jakarta schools hub for the same breakdown.

In Jakarta, families pick Pondok Indah for JIS access, Kemang for BSJ and the bar-and-cafe scene, Senopati and SCBD for younger families near the CBD, and Bintaro for newer compounds.
Lifestyle and climate
Brussels: Temperate maritime, 2 to 8 degrees in winter and 17 to 24 degrees in summer, with grey rainy autumns. Bicycle-friendly inner suburbs, easy weekend trains to Paris, Amsterdam and London, and chocolate-and-frites family weekends. EU expat community is enormous.
Jakarta: Tropical, 24 to 33 degrees year round, with a long wet season from November to April and choking air quality on bad days. Driver-and-staff lifestyle is standard, mall-and-club weekends for kids, and quick flights to Bali, Singapore and Bangkok at weekends. Air quality is the headline downside.
Verdict: who picks which city
Choose Brussels if you want EU-quality healthcare, walking distance to the European Parliament, easy train weekends across Western Europe and the cheapest top-tier IB schooling available in any G7 country via the European Schools system. Pay is taxed but generous EU institution allowances offset the bite.
Choose Jakarta if you want tropical climate, a stretched-far Asian package, world-class IB at JIS, and quick weekend hops to Bali and Singapore. Most relocating families are on full corporate packages that cover tuition, a driver and housing in Pondok Indah. Five-year savings against Brussels can be substantial for families on USD-denominated salaries.
