NSW Boundary Concordance

Four concordances have been calculated for NSW boundaries.

LGA_FederalElectoralDivision_concordance

The dataset shows the relationship between LGA boundaries and\u00a0Federal Electoral Divisions.\u00a0area_ratio\u00a0attribute indicates the portion by area of the LGA within each\u00a0Federal Electoral Division\u00a0area (a value of 1 indicates the LGA is entirely within the given\u00a0Federal Electoral Division). Likewise,\u00a0population_ratio_2021\u00a0attribute indicates the portion by population of the\u00a0LGA\u00a0within each\u00a0Federal Electoral Division\u00a0area.\u00a0\u00a0

LGA_StateElectoralDistrict_concordance

The dataset shows the relationship between LGA boundaries and\u00a0State Electoral Districts.\u00a0area_ratio\u00a0attribute indicates the portion by area of the LGA within each\u00a0State Electoral District\u00a0area (a value of 1 indicates the LGA is entirely within the given\u00a0State Electoral District). Likewise,\u00a0population_ratio_2021\u00a0attribute indicates the portion by population of the\u00a0LGA\u00a0within each\u00a0State Electoral District\u00a0area.\u00a0\u00a0

postcode_LGA_concordance

The dataset shows the relationship between postcodes and LGA boundaries.\u00a0area_ratio\u00a0attribute indicates the portion by area of the postcode within each LGA area (a value of 1 indicates the postcode is entirely within the given LGA). Likewise,\u00a0population_ratio_2021\u00a0attribute indicates the portion by population of the postcode within each LGA area. Postcode boundary is not a standard Spatial Service dataset. It's been derived using suburb that is maintained by Spatial Service. The result is indicative. Where postcode and LGA boundaries do not match exactly, very small percentages might occur.\u00a0

suburb_LGA_concordance

The dataset shows the relationship between suburbs and LGA boundaries.\u00a0area_ratio\u00a0attribute indicates the portion by area of the suburb within each LGA area (a value of 1 indicates the suburb is entirely within the given LGA). Likewise,\u00a0population_ratio_2021\u00a0attribute indicates the portion by population of the suburb within each LGA area.\u00a0A\u00a0population_ratio_2021\u00a0total of 0 for a suburb indicates there is no population estimated in the suburb per the methodology used.\u00a0

Content TitleNSW Boundary Concordance
Content TypeHosted Feature Layer
DescriptionThe\u00a0NSW Concordance\u00a0datasets are a collection of selected boundaries and their spatial relationships to one another. Selected boundary concordances in this dataset include:
  • Ratios of Suburbs in Local Government Areas
  • Ratios of Postcodes in\u00a0Local Government Areas
  • Ratios of Local Government Areas in State Electoral Districts
  • Ratios of Local Government Areas in Federal Electoral Divisions
Ratios area calculated for areas and populations (indicative only). These can differ greatly and are appropriate for different applications. For example, the suburb of Aberdeen is split between Muswellbrook and Upper Hunter LGAs. The area ratios between the LGAs are 0.3888 / 0.6112 and the population ratios are 0.0133 / 0.9867, respectively. So, while a third of the suburb is physically located in\u00a0Muswellbrook\u00a0LGA, nearly the entire suburb population is in\u00a0Upper Hunter LGA.

Update frequencies vary for each dataset based on boundary changes and Census releases.
