Coastal zones are areas with an own identity and specific challenges. The Belgian coastal zone is no different and is characterised by a typical social environment with, among others, an increased population density, a strong aging population, a high number of second-homes, deprived people and a high number of singles. In addition, the Belgian coast is also a specific region in economic terms, with the presence of large economic gateways (sea ports and an international airport), but also increased unemployment, seasonal employment and a limited number of quality jobs for highly educated people. The thematic chapter provides an overview of current knowledge on policy and spatial use, as well as a range of socio-economic figures and measures of sustainability. The figures and underlying data will be made available interactively via the 'Coastal Portal'. More information on the socio-economic expertise present in the Belgian marine research groups can be obtained via 'Research groups'.
