Getting started with the Northern Ireland Life and Times
1. Which dataset do I want?
There are a number of NI Life and
Times Survey (NI LTS) datasets available. Datasets
are available from 1998 onwards.
The Northern Ireland Life and Times
Survey is a direct descendent of the Northern Ireland Social Attitudes Survey
(NISA) which ran from 1989 to 1996. The NISA
datasets are also available.
2. Consulting the documentation
It will not be possible to analyse
the NI LTS survey without reference to the documentation. Documentation is available
for viewing before downloading/ordering the data, however you will also obtain
the documentation if you download the data as a zipped file. The documentation
contains:
o information about how the survey
was carried out
o information about which variables are available
o information about how the data is coded
o the survey questionnaires
The survey questionnaires can also
be obtained on the Survey Question
Bank web site, which provides readily searchable versions of questionnaires
for all major surveys used by secondary analysts.
3. Explore the data online
A good way of starting to explore
the data is to look at the data in Nesstar
WebView.
Nesstar WebView is a data exploration
and analysis tool. It contains many of the NI LTS datasets, as well as some
documentation about the data. Nesstar will allow you to look at univariate frequencies
and variable descriptions without needing to have registered for the data. This
is an excellent way of finding out whether the data are likely to be suitable
for your purposes. You can access Nesstar from the NI LTS datasets pages.
Once in Nesstar, click on the Help
tab in the top right hand corner of the screen to view a user guide.
Once you have registered with ESDS
you will be able to use Nesstar to its full potential, undertaking more complex
analyses and downloading subsets of data in a wide variety of formats.
4. Registering for the data
Once you have decided which data to
use for your project you will need to register
with ESDS to obtain the data. Information about obtaining data can be found
on the ESDS web site.
Registered users can download/order a large and increasing number of datasets
(usually in SPSS, STATA or tab-delimited formats)
via its online catalogue record and via the download/order section of the Major
Studies web pages.
5. Downloading the data
Once registered you may either:
o download the data directly as
a zipped ASCII, STATA or SPSS file. This download will also include necessary
documentation
o download an entire file, or a subset of your choice, into a wider range
of formats via Nesstar Light
6. Analysing the data using an appropriate analysis package
Because the NI LTS datasets are microdata
you will need to analyse them using an appropriate package.
You can undertake straightforward
analysis, including linear regression, on the whole dataset or a subset, using
Nesstar. However, it is not possible to produce derived variables or do more
advanced analyses using Nesstar, to do this you will need to use a package like
SPSS, STATA or SAS.
If you are unfamiliar with these packages
you can find a STATA
guide on the ESDS Government pages, which uses examples from the Labour
Force Survey. A guide to SPSS is also available, based on the HSE 2002 teaching
dataset. Several organisations offer introductory SPSS and STATA courses. CCSR
at the University of Manchester offers one-day courses although there is a charge.
Details of these courses can be obtained through the CCSR
Short Course Pages.

8. Publishing
We need to let other researchers and
data depositors know what publications are available using the NI LTS. If you
publish using the data, please contact us at govsurveys@esds.ac.uk and give
us details of your publication. If you would be happy for us to publish something
on our web site, for example the research
story on smoking, please let us know.
Data collectors and distributors should
be acknowledged in publications.
