Population and places through time: Grid-square data and the NILS

QUB and NILS-RSUSlide2
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)Slide3Slide4
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 Slide5
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 CensusesSlide6Slide7Slide8
1971: Percentage Catholic by 100m grid squaresSlide9
1991: Percentage Catholic by 100m grid squaresSlide10
2001: Percentage Catholic by 100m grid squaresSlide11
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 Slide12
The NILS
28% sample is large enough to consider small areas (SOAs) or population groups
in context

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?Slide15
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 2011Slide16

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 workSlide20
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 ResourceSlide21
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 timeSlide22
