NILS Synthetic Data Spine

The NILS synthetic data spine is now available for downloading here.

A simple proportional fitting algorithm has been used to extend the national 2011 Census Microdata Teaching files (derived from the Samples of Anonymised Records) to include longitudinal transitions (currently a ten year transition back to 2001), derived from the real LS data.  The synthetic spine state transitions are for some of the most commonly used variables in social science research, including health, marital status, and religion, as well as estimates for the numbers of births and deaths.  These data are for general use and will allow users who are unfamiliar with longitudinal data to get a feel for the kinds of questions that can be answered by following individuals through time and observing changes in their characteristics.

Please note, the NILS synthetic data spine contains synthetic data based on the NILS and does not contain real NILS data.  Real NILS microdata are available in the secure environment in NISRA Headquarters, Colby House, Belfast.  The microdata are never released outside of this secure environment.  Researchers may apply to use the NILS data by contacting NILS-RSU.

Further information on synthetic LS data, including the downloadable synthetic data spines for the NILS, the ONS LS and the SLS can be found on the CALLS-HUB website.

NI Science Festival - What Big Datasets Can Tell Us About Population Change & Health in Northern Ireland


Dr Stefanie Doebler (Northern Ireland Longitudinal Study); and 

Ms Siobhan Morgan (Honest Broker Service, BSO).


The “Big Datasets” event at the NI Science Festival was organised by Stefanie Doebler and introduced how demographers and geographers use population data from Northern Ireland to answer questions about population health and changing life circumstances over time.

The two speakers, Stefanie Doebler (school of GAP, QUB, NILS-RSU) and Siobhan Morgan (Honest Broker Service, BSO) introduced two major data sources, the Northern Ireland Longitudinal Study (NILS), which is the largest representative longitudinal population study existing in the UK and large, unique health data from the Business Services Organisation (BSO).

Emphasis was placed on what uses stakeholders and policymakers have for analyses based on large population data and how research using these data can help shape policy.

Figures and examples showed how social change & population health can be graphed and mapped to answer questions about neighbourhoods, families, health, housing and more.

The event was a success and we look forward to running similar events at the next Science Festival.

Friday 26th February 2016.

Research Forum Course - Demographic Methods using Longitudinal and Area-Data

Instructor: Dr Paul Norman (University of Leeds)

11th & 12th January 2016, 9.30-16.00

Queen’s University Belfast, McClay Library Training Room 2


Day 1: Demographic Analysis of Area, Individual and Longitudinal Data

This one day course will provide contexts for and practical experience of calculating demographic measures relating to population structure, fertility, mortality / illness and migration. We will first concentrate on demographic data for geographical areas. This will include devising population pyramids and calculating fertility rates, standardised mortality / illness ratios and migration rates. We will then switch to the use of cross-sectional individual microdata and the cross-tabulation of variables to differentiate demographic rates by different population sub-groups (e.g. self-reported health by ethnic group). Longitudinal microdata will then by used to show how demographic rates change over time.

Data sources to be used:

Area measures: Vital Statistics, census and mid-year estimates for local authority geographies; Individual microdata, cross-sectional: the ‘2011 Census Microdata Teaching File’ (similar to Sample of Anonymised Records); Individual microdata, longitudinal: a synthetic dataset linking individuals from 1991 to 2001; Data and contexts are UK-focussed.

Mathematical and statistical methods & software being used:

Mainly the calculation of rates (based on numerator / denominator) with consideration of related confidence intervals and binary logistic regression; Excel for the area data and SPSS for the individual data.


Day 2: Measures of Deprivation and Area Type

Deprivation indexes and geodemographic classifications aim to reduce multidimensional attributes of areas to a single score or summary description which captures the essence of each area’s characteristics. Deprivation measures and geodeomographic schemes are widely used in research on spatial variations in many phenomena, ranging from health and crime to education and economic activity but the strengths and weaknesses of these measures is often poorly understood. This course will first explain the geographies which are used for deprivation and geodemographics schemes and the data sources which are used as inputs. Then, ‘traditional’ measures of area deprivation will be explained followed by a practical in which participants will calculate small area deprivation. Then, the methods underpinning geodemographics will be explained along with their usage in both commercial and academic situations. Participants will then develop a classification using ‘k-means’ one of the regularly used approaches.

Data sources to be used:

For both the deprivation index and classification practicals, data will be from the 2001 Census and for the Lower Super Output Area geography; If the course presenter gets time, equivalent datasets for small areas in Northern Ireland will also be made available so that participants can use these. At the time of writing, no promises are given!

Mathematical and statistical methods & software being used:

There are some examples of calculations in Excel but the practical work will all be carried out using SPSS. It is possible to calculate the deprivation measures with the methods here using Excel but the classifications method needs SPSS (or other statistical packages not used in this course);

Preliminary requirements: Previous experience of these programmes is ideal along with basic mathematics and statistics.

Each of these two courses is a day-event in its own right and can be booked as a standalone, but it is recommended to take them both in combination, as they complement each other.

The courses are aimed at NILS-researchers, academics and postgraduate students from QUB, Ulster University and NILS/NISRA staff. The events are free of charge for NILS-users, students and academic users, staff at Queen's, Ulster University, NILS-RSU, NISRA, and HSCNI. If you would like to participate and secure your place, please send an email to, with your name, email address and role and affiliation (NILS-user or not, University, staff/student).
