Overcrowded households (Percentage) - Birmingham Constituency

This metric provides a measure of whether a household's accommodation is overcrowded or under occupied. It is calculated by summing households with one room too few and households with two or more rooms too few, as a percentage of all households. The ages of the household members and their relationships to each other are used to derive the number of rooms/bedrooms they require, based on a standard formula. The number of rooms/bedrooms required is subtracted from the number of rooms/bedrooms in the household's accommodation to obtain the occupancy rating. An occupancy rating of -1 implies that a household has one fewer room/bedroom than required, whereas +1 implies that they have one more room/bedroom than the standard requirement. Statistical Disclosure Control: In order to protect against disclosure of personal information from the Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.Data is Powered by LG Inform Plus .

本指标衡量一户家庭的住宿是否过度拥挤或不足。该指标通过将房间数量不足一间及房间数量不足两间或以上的家庭数量相加，并以此占所有家庭总数的百分比来计算。家庭成员的年龄及其相互关系被用来根据标准公式推导出他们所需的房间/卧室数量。所需房间/卧室数量从家庭住宿中的房间/卧室数量中减去，以获得入住率。入住率为-1表示家庭比所需房间/卧室少一间，而+1则表示家庭比标准需求多一间。统计披露控制：为防止人口普查中个人信息的披露，已在人口普查数据库的不同地理区域之间交换记录，因此某些计数将受到影响。总体而言，影响最大的将是最低地理级别的数据，因为记录交换主要针对小区域内具有异常特征的家庭。数据由LG Inform Plus提供。
