LPS Harmonised Demographic Dataset (full)#
Last modified: 27 Oct 2025
1. Summary#
The full LPS harmonised demographic dataset contains harmonised variables for sex, gender, year of birth and ethnic group. This dataset retains every relevant response provided by participants. For example, if a participant was asked to confirm their ethnic group on five separate occasions, then that individual will have five occurrences of ethnicity in this dataset.
