For instance,

The apartment we are moving into has 130 m² for 4 people. That gives each adult a comfortable 32,5 m²/person, with only one kitchen, living room, laundry room, and bathroom, for everyone to share. That used to be considered spacious.

This now would be considered a home for two or three people, so we would need 190 m² and twice the number of amenities, to house the same number of people, in order to meet the national living standard of 47,4 m²/person, and a bathroom for every 2 people.
