Mesh Blocks are a new small area unit introduced by the ABS for the 2006 Census. They will not be fully integrated with the ASGC until after the review of the ASGC that is planned to be completed by July 2008. An information paper Review of the Australian Standard Geographical Classification 2007 (cat. no. 1216.0.55.001) has been published and a request for submissions has been made as part of the review.
