Jette, Belgium

With a population density of over 27,000 per square mile, Jette is a densely packed Brussels suburb that's lost much of its rural charm. The municipality's population has more than quadrupled since 1900, reaching over 54,000 as of 2024. While the area retains some historical sites like the Dieleghem Abbey, the relentless bureaucracy and red tape left behind by the French Revolution is a persistent headache for residents.

Jette's convenient location and access to the Vrije Universiteit Brussel hospital campus make it a practical option for medical professionals, but the lack of green space and small-town character mean it's unlikely to appeal to those seeking a quieter lifestyle.
