Northern Ireland Longitudinal Study (NILS)


The Northern Ireland Longitudinal Study (NILS) is a large-scale data linkage study which has been created by linking administrative and statistical data. The Study is designed for statistical and research uses only and is managed under Census legislation. Information is linked over time on people from Census, vital events and health registration datasets. Data sources include 2001 Census data, birth and death registrations and demographic data derived from health registrations.
