Data Access

NIDS Wave 5 data is now available, together with updated versions of Wave 1, Wave 2, Wave 3 and Wave 4. Data cleaning has been ongoing since the last release and new variables have been added. Please download the latest data.

The data files are available in Stata format only. Previously, the data was made available in R, SAS, and SPSS. However, these programs now have a functionality to import Stata files. NIDS data is hosted through the DataFirst online data site Clicking on a dataset link below will take you to the relevant page on the DataFirst data site. Once there, to download the data files click on the "Get Microdata" tab.
