When large Urban Centres (over 20,000 people) grow they can expand in area to become adjacent to other smaller, nearby Urban Centres. When this occurs the two Urban Centres are amalgamated to become a single Urban Centre. Figure 2 shows an example of this for the Urban Centres of 'Heddon Greta' and 'Kurri Kurri - Weston'.

In a very small number of cases the opposite can occur and Urban Centres can be de-amalgamated. This can occur as a result of changes to SA1 boundaries which allow the Urban Centres to be defined more accurately. The most significant example of where this has occurred in 2016 is the de-amalgamation of Victor Harbor – Goolwa in South Australia.
This publication includes the ‘UCL_association_2011_2016.csv file’ which is located in the Downloads tab. This associates 2011 UCLs with an equivalent 2016 UCL to help users understand changes and make statistical comparisons between UCLs over multiple Censuses. This table includes information on the area of the UCLs as well as the following types of changes:
· De-amalgamated – When UCLs have been split to create several UCLs.
· Name Change – When an UCL has changed name. This includes the addition or removal of the (L) at the end of a name to symbolise if a UCL is a Locality.
· New – When an UCL is new for 2016.
· Removed – When an UCL no longer meets the criteria and is removed from the UCL structure.
ABS Maps is an online mapping tool that allows users to visualise the boundaries and understand differences between different Australian Statistical Geography Standard (ASGS) boundaries, for example the 2011 and 2016 UCLs. This can be used in conjunction with the ‘association file’ to understand the UCL boundaries and any changes that have occurred.
These documents will be presented in a new window.
