1. Population and places through time: Grid-square data and the NILS Ian Shuttleworth QUB and NILS-RSU

2. Outline What data resources are available to profile local communities? How can change through time be mapped for small areas with available data? How can these data resources be accessed? What are your information needs and how might they be met? Focus on the Grid-Square Resource and the Northern Ireland Longitudinal Study (NILS)

4. The Grid-Square Resource 1km (everywhere 1971-2001) and 100m cells (Belfast 1971-1991, everywhere 2001) Geographically standard and consistent spatial units through time – unlike other census output geographies – which can change between Censuses Counts of population for all cells; if more than 8 households and more than 25 individuals then other counts

5. The Grid-Square Resource Topic counts: for example, housing tenure, car ownership, age group, community background Profile small areas 1971, 1991, 2001 (and next year) 2011 plus change between these years Data can be obtained from NISRA Standard NI Census output but not as easy to use as other outputs Requires GIS capability and also understanding variable definition in various Censuses

11. The NILS Established in 2006; designed to examine change through time, mortality, fertility, mobility Based on a 28% sample (104/365 birthdates) of health card registrations which is linked to the 2001 Census, and soon the 2011 Census, and then the 1991 Census (c500,000 people) Plus births and deaths in intervening years Possible by 2014 (and 2001-2011 by late 2013) to examine population and social changes 1991- 2011

12. The NILS 28% sample is large enough to consider small areas (SOAs) or population groups in context Data accessed via the NILS-RSU – http://www.qub.ac.uk/research- centres/NILSResearchSupportUnit/AvailableData/ http://www.qub.ac.uk/research- centres/NILSResearchSupportUnit/AvailableData/ Staff can help in understanding more about the data and the range of relevant possible projects that might be of interest

14. The NILS Example use of the NILS – a possible research project Questions: – Who moves into and out of socially-deprived areas? – What happens to (a) people who move out of socially-deprived areas and (b) people who move into socially deprived areas after (i) 5 years (ii) 10 years?

15. The NILS The NILS could be used by Autumn 2013 to answer these questions by: – Locating people in 2001 and profiling their social, household and demographic characteristics using the 2001 Census – Health card registration data (address changes) could then by used to locate them in 2005 and 2011 to find out if people had moved and, if so where they had moved to – Then data from the 2011 Census could be used to their social, household and demographic characteristics – were moves out deprived areas, for instance, associated with a greater chance of employment in 2011

17. Area Change - No Policy Intervention 2001 Least Deprived Most Deprived 2011 Least Deprived Most Deprived Migration Effects + - BirthsDeathsBirthsDeaths

19. Conclusion The Grid-Square Data and the NILS are powerful resources for understanding localities and population dynamics These resources are publicly funded – they therefore should be used as widely as possible for the public good There are many different ways to use these resources – You might be a consumer of research findings produced by someone else as part of their work

20. Conclusion Using these resources – You might commission someone to do specific work that you define – You may use the data yourselves The NILS-RSU exists to promote the NILS data and to help both new and experienced users to develop and undertake projects – One of its purposes is to build capacity in using the NILS More capacity building is needed to make use of the Grid-Square Resource

21. Conclusion Using the Grid-Square resource – The data can be accessed from the NISRA website – Academics or other experienced data users may be able to advise on mapping and using the data to examine change through time
