Standard of equipment

As from 2005, only two categories are used to describe the standard of equipment:
- High standard of equipment: the dwelling has running water, sewage, hot water, toilet, washing facilities (shower/bathroom or sauna) and central or electric heating
- Other or unknown level of equipment.

In the previous years, three categories have been used to describe the standard of equipment in a dwelling:
- High standard of equipment: the dwelling has running water, sewage, hot water, toilet, washing facilities (shower/bathroom or sauna) and central or electric heating
- low standard of equipment: the dwelling only lacks washing facilities and/or central heating (or electric heating)
- substandard of equipment: the dwelling lacks one of the following facilities: running water, sewage, hot water or toilet.
