Number of non-rentable SLSP dwellings

The indicator relates the number of public dwellings owned by one of the public service housing corporations (PSHCs) that are not rented to all dwellings owned by the PSHCs. This is in fact the following fraction: (sum of ‘unleased but rentable dwellings’ and ‘unleased and non-rentable dwellings’)/(sum of ‘leased dwellings’, ‘unleased but rentable dwellings’ and ‘unleased and non-rentable dwellings’).
SLSPs rent several types of housing: ‘social’ housing, ‘medium’ housing, ‘integration’ housing, ‘transit’ housing, ‘equilibrium rent’ housing and ‘student’ housing. Access and rental conditions vary from one type to another.
Note that only dwellings owned and managed by SLSPs are counted here.
Other public operators (CPAS, municipalities, AIS, etc.) also rent accommodation for similar groups.
Break in series:
Following a transfer of responsibility for housing to the German-speaking Community, housing on its territory is not included in the SWL statistics as of 1/1/2021 and will no longer be included in the future. This implies a decrease in numbers and proportions on the aggregates including the 9 German-speaking municipalities.

该指标用于计算某公共服务住房公司（Public Service Housing Corporations，PSHCs）名下未出租公共住宅数量，占该公司全部自有住宅总量的比值。其本质为以下分式：（「未出租但可租赁住宅」与「未出租且不可租赁住宅」的总数量） / （「已出租住宅」、「未出租但可租赁住宅」与「未出租且不可租赁住宅」的总数量）。
社会住房服务提供商（Social Landlord Services Providers，SLSPs）提供多种类型的租赁住宅：包括「社会型住宅」、「中等型住宅」、「融合型住宅」、「过渡型住宅」、「均衡租金住宅」以及「学生住宅」。不同类型住宅的准入规则与租赁条件各有差异。
请注意，本次统计仅涵盖社会住房服务提供商（SLSPs）自有并管理的住宅。
其他公共运营主体（如CPAS、地方市政当局、AIS等）也会为同类群体提供租赁住房。
序列断点说明：
随着住房管理职责移交至德语区共同体，自2021年1月1日起，该区域内的住宅不再纳入SWL统计范畴，且未来也不会再被纳入统计。这将导致包含9个德语区市镇在内的整体统计数据集的数值与占比出现下降。
