Valais projects 67,700 population increase by 2055, driven by immigration

The Swiss canton of Valais anticipates significant population growth by 2055, with projections indicating an increase of 67,700 residents. This surge is expected to bring the canton's total population to 443,765, according to a medium-scenario projection. The growth is largely attributed to immigration, which is outpacing emigration, and is particularly strong in the Lower Valais region.

This demographic shift is occurring against a backdrop of an aging population. The proportion of residents aged 65 and over is set to rise from 21% to 31% by 2055, while the younger demographic (under 20) is expected to decline from 19% to 15%. Consequently, the average age of Valaisans will increase from 43.2 in 2024 to 48.9 in 2055. The ratio of active workers to retirees will also shift, from 2.9 to 1.8.

These projections represent an important management tool for various areas, such as training, spatial planning, public health – a priority –, mobility and transport, housing, social action, and public finances.

While most districts are expected to see population increases, with Martigny, Brig, and Sion leading the growth, three districts, Conches, Hérens, and Raron, may experience a population decline. The study's projections do not account for the impacts of climate change. Officials view these demographic forecasts as crucial tools for planning across various sectors, including education, spatial planning, public health, transportation, housing, social services, and public finances.

We would reach 396,000 people, in the low scenario and 488,000, in the high scenario.
