The Australian Bureau of Statistics created the Personal Income Tax and Migrants Integrated Dataset (PITMID) by linking Australian Taxation Office personal income tax records with migrant records from the Australian Government’s Settlement Database (SDB). In 2015, PITMID data for 2009–10 and 2010–11 was released in Personal Income of Migrants, Australia, Experimental (ABS cat. no. 3418.0). In 2016, this PITMID study was conducted to assess the effects of a change in the linking methodology for the 2011–12 PITMID. The study briefly outlines the original and new linking methodologies and presents the results of the analyses conducted to assess the quality of the 2011–12 PITMID linkage compared with the 2009–10 and 2010–11 PITMID linkages. The new deterministic record linkage methodology was found to be much quicker to administer and produced high quality results, while enabling comparison between the annual series.
