Census 2021 Second Address Indicator - Birmingham Wards

This dataset provides Census 2021 estimates that classify usual residents in England and Wales by their use of a second address, and whether the second address is inside or outside the UK. The estimates are as at Census Day, 21 March 2021.An address (in or out of the UK) a person stays at for more than 30 days per year that is not their place of usual residence. Second addresses typically include: * armed forces bases * addresses used by people working away from home * a student's home address * the address of another parent or guardian * a holiday homeIf a person with a second address was staying there on census night, they were classed as a visitor to the second address but counted as a usual resident at their home address.CoverageThis dataset is focused on the data for Birmingham at Ward level. Also available at LSOA, MSOA and Constituency levels.About the 2021 CensusThe Census takes place every 10 years and gives us a picture of all the people and households in England and Wales.Protecting personal dataThe ONS sometimes need to make changes to data if it is possible to identify individuals. This is known as statistical disclosure control. In Census 2021, they:Swapped records (targeted record swapping), for example, if a household was likely to be identified in datasets because it has unusual characteristics, they swapped the record with a similar one from a nearby small area. Very unusual households could be swapped with one in a nearby local authority.Added small changes to some counts (cell key perturbation), for example, we might change a count of four to a three or a five. This might make small differences between tables depending on how the data are broken down when they applied perturbation.For more geographies, aggregations or topics see the link in the Reference below. Or, to create a custom dataset with multiple variables use the ONS Create a custom dataset tool.Population valueThe value column represents All usual residents.The percentage shown is the value as a percentage of All usual residents within the given geography.

本数据集提供了2021年人口普查的估计数据，该数据根据居民是否使用第二居住地址以及该地址位于英国境内或境外，对英格兰和威尔士的常住居民进行分类。估计数据以普查日，即2021年3月21日的状态为准。地址（无论位于英国境内还是境外）系指个人每年居住超过30天的地点，但并非其常住居住地。第二居住地址通常包括：* 军事基地 * 工作地点远离家的个人使用的地址 * 学生的家庭住址 * 另一位父母或监护人的地址 * 度假别墅。如果拥有第二居住地址的个人在普查之夜居住在该地址，则被归类为第二居住地址的访客，但计为其家庭住址的常住居民。数据覆盖范围本数据集专注于伯明翰地区的区域数据。此外，还可在LSOA、MSOA和选区级别获取。关于2021年人口普查人口普查每十年进行一次，为我们呈现了英格兰和威尔士所有人口和家庭的状况。保护个人数据国家统计局有时需要修改数据，如果有可能识别个人，这被称为统计披露控制。在2021年人口普查中，他们采取了以下措施：* 交换记录（目标记录交换），例如，如果某个家庭因具有不寻常的特征而在数据集中可能被识别，则将其与附近小区域中相似的记录进行交换。非常不寻常的家庭可能被与附近地方政府的一个家庭进行交换。* 对某些计数进行微小调整（单元键扰动），例如，我们可能将四个计数更改为三个或五个。这可能会根据数据在应用扰动时的细分方式导致表格之间出现微小差异。有关更多地理、聚合或主题信息，请参阅以下参考资料中的链接。或，要创建包含多个变量的自定义数据集，请使用国家统计局的自定义数据集工具。人口值值列代表所有常住居民。显示的百分比是作为给定地理区域内所有常住居民的百分比。
