Maximising the value of the 2021 Northern Ireland Census

2021年北方爱尔兰人口普查的查点率为97%，非常成功。2021年人口普查建立在数据区（DZ）和超级数据区（SDZ）的新的、更有效的输出地理基础上。新的区域/地区比以前的输出地区更好地代表2021年的人口。然而，这种代表性的改善突出了一个重要的弱点：新的地理位置与（a）以前的人口普查和（B）为旧地理位置提供的行政数据（例如2014年选举区）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区联系起来进行时间分析，为所有用户增加了价值。我们的目标是创建：为较旧的行政或统计地理区域（如选举区）创建2021年人口普查输出，以及用于传播2011年人口普查输出的超级输出区。将人口普查小区域统计数据的时间范围扩展到选定地理区域的2001年，1991年，1981年和1971年。提供一个空间框架，将2021年人口普查输出地理区域与替代输出地理区域联系起来，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：1971年至2021年人口普查相关的可供研究的一致数据集。一个面向外部的网络资源，将允许非专家用户评估（a）研究界和（B）更广泛的非专家用户对这些产品的需求都有文件记录。这些目标和数据产出通过创建“能够利用普查数据进行研究的工具和研究就绪的数据集”以及处理“与其他数据来源（包括政府行政数据）相关联的普查数据”和“纵向关联的普查数据”来满足这一呼吁的标题。我们的项目将通过利用以下优势实现其目标和目的：NISRA和ESRC之前对独特的100米和1公里NI网格广场产品（GSP）（1971-2021）的投资。这些数据将被充分记录和准备，以便㈠在一个普查年度使用; ㈡在两次或多次普查中进行时间比较。将创建查找表，以通过最佳拟合近似将100米网格与选定的统计地理区域联系起来。此外，还将探讨建立用户定义的社区。NISRA数据门户。从这些广泛的数据（如入学率，福利计数）代表在选区一级的选定领域将通过查找表与2021年人口普查（和其他年份）数据相关。共同设计，社区推广，以及在QUB中创建网络资源的经验（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。该项目将在2024年3月至2026年3月之间运行。维持和更新网络资源需要最低限度的持续支持。

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.
