The Northern Ireland Longitudinal Study (NILS) is a wide-ranging database of people and their major life events, stretching back decades. Census information for 1981 to 2011 is linked with other administrative datasets such as vital events, school data, property information, health card registrations, weather and pollution amongst others.

The data can provide evidence for research into social issues and the evaluation of government policies.
