In the state of New South Wales, Australia, there are many areas which are commonly known by regional names. Regions are areas that share similar characteristics. These characteristics may be natural such as the Murray River, the coastline, or the Snowy Mountains. Alternatively, the characteristics may be cultural, such as a viticulture land use. New South Wales is divided by numerous regional boundaries, based on different characteristics. In many cases boundaries defined by different agencies are coterminous.
Local government
In New South Wales on the third tier of elected government after the federal and state governments are the local government authorities, which are responsible for the local government areas. The types of LGAs in New South Wales are cities, municipalities, shires and regions.
New South Wales has more than 150 local government areas which have an elected council and carry out various functions delegated to them by the Government of New South Wales.
Australian Bureau of Statistics
The Australian Bureau of Statistics has moved towards a new Geographical Classification called the Australian Statistical Geography Standard. Geography is now divided into Statistical Area Level 1, 2, 3, and 4. Statistical Area Level 4 is the highest (regions of a State) and Statistical Area Level 1 being the lower (Mesh blocks are more refined but not readily available apart from the Census of Population and Housing).
For older statistics, such as the 2006 Census of Population and Housing, the Australian Bureau of Statistics has multiple regional structures for which it analyses and reports data. These regional structures derive from the Australian Standard Geographical Classification (AGSC). The AGSC defines at the very smallest level, the Census Collection District (CCD). These CCD's aggregate to form the Statistical Local Area (SLA), which is the common base unit for each of the larger regional structures. The boundaries of the SLA are designed to be typically coterminous with Local Government Areas unless the LGA does not fit entirely into a Statistical Subdivision (SSD), or is not of a comparative nature to other LGA's. Bureau of Statistics provides statistics for Local Government Areas, as well as three other statistical structures: Statistical Divisions, Statistical Regions, and Statistical Districts.
Statistical Divisions
Statistical Divisions (SD) form the main structural hierarchy of statistical analysis. These regions are structured to provide a broad range of social, demographic and economic statistics. The basis for the boundary delineations center on socioeconomic criteria. The thirteen divisions for New South Wales are: Central West, Far West, Hunter, Illawarra, Mid-North Coast, Murray, Murrumbidgee, North Western, Northern, Off-Shore Areas & Migratory, Richmond-Tweed, South Eastern, Sydney
Statistical Regions
The Statistical Region (SR) structure was established in 1986 as a means for labor force analysis. Sydney: Canterbury-Bankstown, Central Northern Sydney, Central Western Sydney, Eastern Suburbs, Fairfield-Liverpool, Gosford-Wyong, Inner Sydney, Inner Western Sydney, Lower Northern Sydney, North Western Sydney, Northern Beaches, Outer South Western Sydney, St George-Sutherland Balance of New South Wales: Central West, Far West-North Western, Hunter, Illawarra, Mid-North Coast, Murray-Murrumbidgee, Northern, Richmond-Tweed, South Eastern
Statistical Districts
The Statistical District (SDist) is a non-capital, urban region of one or more adjoining areas, with a population of 25,000 or more. The SDist is defined with consideration of a 20-year growth forecast. The SDist does not need to conform to LGA boundaries or to state territory boundaries. The thirteen Statistical Districts in New South Wales are: Newcastle, Wollongong, Nowra-Bomaderry, Bathurst-Orange, Lismore, Coffs Harbour, Port Macquarie, Tamworth, Dubbo, Wagga Wagga, Albury-Wodonga (New South Wales and Victoria), Gold Coast-Tweed (New South Wales and Queensland), Canberra-Queanbeyan (New South Wales and the Australian Capital Territory)
