TECHNICAL NOTE Northern Territory 2017 Motor Vehicle Census Data Undercount


INTRODUCTION


1Care should be taken when interpreting 2017 registration counts for the Northern Territory. In the course of processing the 2018 Motor Vehicle Census it became apparent that there were a small number of vehicle registrations not included in the 2017 published estimates for Northern Territory. This Technical Note gives a brief description of the issue and provides estimates of the extent of the undercount in the NT data.

2 As the Motor Vehicle Census is an annual snapshot of the number of vehicles in the various state and territories vehicle registrations database at a specific point in time (31 January), it will be very difficult to recreate the snapshot for 2017. Therefore estimates presented in the 2017 MVC releases - Motor Vehicle Census, Australia, 31 Jan 2017 (cat no.9309.0) and Microdata: Census of Motor Vehicles, Australia, 2017 (cat no. 9309.0.55.003) will not be revised.

ADJUSTED ESTIMATES


3 The table below presents an estimate of 2017 NT vehicle registrations by vehicle type. Overall, approximately 3% (4,890) of NT registrations were omitted from the 2017 release.

4 Please note, there is an additional undercount of 659 registrations affecting NT in the 2017 MVC TableBuilder product. These extra registrations are out of scope of the MVC web release but included in the MVC TableBuilder product as they relate to registration of other vehicle types such as concessional vehicles, caravans, plant and equipment and trailers.
