The Quarterly National Household Survey (QNHS) began in September 1997 and ran until Q2 2017 when it was replaced by the Labour Force Survey (LFS). While the main purpose of the QNHS was the production of quarterly labour force estimates, there is also a provision for the collection of data on social topics through the inclusion of special survey modules. The QHNS also conducted special modules on different social topics each quarter. This is the special modules on pensions from 2005-2008.
