Nantes Métropole is a French metropolis in the loire-Atlantique département and Pays de la loire region. It was home to 672,420 inhabitants in 2020. Nantes Métropole is one of France's most dynamic metropolitan areas. Indeed, Nantes Métropole's territory has experienced strong demographic growth in recent years.

 

The population grew by 21% between 1999 and 2020, with year acceleration in the last decade. Between 2014 and 2020, more than 8,500 people will have moved into the area each year. Welcoming this new population requires appropriate planning in terms of housing, social, cultural and educational facilities, as well as infrastructure and economic activity. This planning is a major challenge for maintaining quality of life and preserving the region's environmental conditions, in short, it is crucial if the Metropolis is to achieve carbon neutrality by 2030.
