The purpose of the Partnership Histories dataset is to merge all data on live-in relationships in successive sweeps into one longitudinal dataset. For the fifth edition (January 2026), the data has been updated to include partner data collected at sweep 11 (2021, Age 51) and includes partner information up to the date of interview between 2021 and 2024.
