Maximising the value of the 2021 Northern Ireland Census

2021年北爱尔兰人口普查非常成功，人口普查率为97%。2021年人口普查是建立在数据区（DZ）和超级数据区（sdz）的新的和更有效的输出地理基础上的。新的区域/地区比以前的输出地理区域更能代表2021年的人口。然而，这种代表性的改善凸显了一个重要的弱点：新的地理位置与(a)以前的人口普查和(b)旧地理位置（如2014年选举选区）提供的行政数据不向后兼容。我们解决了这一弱点，并通过将2021年人口普查与其他输出地理区域联系起来进行时间分析，为所有用户增加了价值。我们的目标是：为旧的行政或统计地区（如选举区）创建2021年人口普查产出，以及用于传播2011年人口普查产出的超级产出区。将选定地区的普查小地区统计数据的时间范围延长至2001年、1991年、1981年和1971年。提供一个空间框架，将2021年人口普查产出区域与其他产出区域联系起来，这将有助于与行政数据源和多重剥夺指数进行比较。目标是创建一个与1971年至2021年人口普查相关的研究准备一致的数据集。一个面向外部的网络资源，允许非专业用户评估用户定义的小区域是如何随时间变化的。明确说明数据是如何编制、处理和编码的，以便在必要时进行人口普查比较，记录人口普查之间的数字、定义和问题范围的变化。对这些产品的需求记录来自(a)研究界和(b)更广泛的非专业用户社区。这些目标和数据输出符合呼吁的主题，通过创建“工具和研究就绪的数据集，使研究能够使用人口普查数据”，并使用软件工具处理“与其他数据来源（包括政府行政数据）相关的人口普查数据”和“纵向关联的人口普查数据”，以更好地利用2021年人口普查数据。我们的项目将通过利用：NISRA和ESRC之前对独特的100米和1公里NI电网平方产品（GSP）（1971-2021）的投资来实现其目标和目标。这些数据将被充分记录和编制，以便(i)在单一人口普查年度使用；（ii）进行两次或以上人口普查的时间比较。将创建查找表，通过最佳拟合近似将100米网格与选定的统计地理联系起来。此外，还将探索用户自定义社区的创建。NISRA数据门户。从这些广泛的数据中选出的领域（如入学率、福利计数）将通过查找表与2021年人口普查（和其他年份）的数据相关联。共同设计，社区外展，和在QUB的网络资源创造的经验（https://www.qub.ac.uk/sites/qcap/about-us/QCAPApproach/）。这将用于了解哪些主题领域是有价值的，以及如何使网络资源易于使用。该项目将于2024年3月至2026年3月期间运行。维护和更新web资源将需要最少的持续支持。

With a 97% enumeration rate, the 2021 Northern Ireland Census was highly successful. The 2021 Census is built on a new and more efficient output geography of Data Zones (DZ) and Super Data Zones (SDZs). The new Zones/areas better represent the 2021 population than the previous output geographies. Yet this improvement in representation highlights an important weakness: the new geography is not backward-compatible with (a) previous censuses and (b) administrative data presented for older geographies (eg 2014 electoral wards). We address this weakness and add value to the 2021 Census for all users by linking it to other output geographies for temporal analysis. Our objectives are to create:Create 2021 Census outputs for older administrative or statistical geographies such as electoral wards, and Super Output Areas used for dissemination of outputs from the 2011 Census.Extend the temporal range of census small-area statistics back to 2001, 1991, 1981 and 1971 for selected geographies.Provide a spatial framework that will link 2021 Census output geographies to alternative output geographies, which will assist comparisons with administrative data sources and indices of multiple deprivation.The objectives are to create:A research-ready consistent dataset relating to censuses from 1971 to 2021.An outward-facing web resource that will allow non-expert users to assess how small user-defined areas have changed through time.Clear documentation of how the data have been created, processed and coded, where necessary, to make cross-census comparisons, recording changes in numbers, definitions and scope of questions between censuses.There is a documented demand for these products from both (a) the research community and from (b) wider communities of non-expert users. These aims and data outputs meet the call's rubric by creating "tools and research-ready datasets that enable research with census data" and dealing with "census data linked to other sources of data (including government administrative data)" and "census data that has been linked longitudinally." with software tools to make better use of 2021 Census data.Our project will achieve its aims and objectives by taking advantage of:Previous NISRA and ESRC investments in the unique 100m and 1km NI Grid-Square Product (GSP) (1971-2021). These data will be fully documented and prepared for (i) use in single census years; and (ii) for temporal comparisons over two or more censuses. Look-up tables will be created to relate the 100m grid to selected statistical geographies via best-fit approximation. Additionally, the creation of user-defined neighbourhoods will be explored. The NISRA data portal. Selected domains from these extensive data (eg school attendance, benefit counts) represented at electoral ward level will be related to 2021 Census (and other years) data via the look-up tables.Co-design, community outreach, and experience in web resource creation in QUB (https://www.qub.ac.uk/sites/qcap/about-us/QCAPApproach/). This will be used to understand what thematic areas are of value and also how to make the web resource easy to use.This project will run between March 2024 and March 2026. Minimal continued support will be necessary to maintain and update the web resource.
