An Urban Centre is generally defined as a population cluster of 1,000 or more people. A Locality is generally defined as a population cluster of between 200 and 999 people. People living in Urban Centres are classified as urban for statistical purposes while those in Localities are classified as rural (i.e. non-urban). Each Urban Centre and/or Locality (UC/L) is bounded (i.e. a boundary for it is clearly defined) and composed of one or more whole Collection Districts (CDs). UC/Ls are defined for each Census and are current for the date of the Census. The criteria for bounding UC/Ls are based on the Linge methodology.
For more information and a list of the UC/Ls for 2006, refer to Statistical Geography Volume 3: Australian Standard Geographical Classification (ASGC) Urban Centres/Localities (cat. no. 2909.0).
