Collection and usage attributes

Population group age from:

18 years and over

Computation description:

Presented as a number per 100,000 people, age standardised, by Statistical Area Level 4.

Analysis by Statistical Area Level 4 (SA4) is based on postcode of usual residence of the patient. The postcode is based on that which is provided by the patient to the hospital at which they are admitted.

SA4s where the total population was less than 2,500 or where the population of people aged 18 years and over was less than 200 are excluded.

Suppression protocol for calculating age-standardised rates:

Numerator	Total admissions less than 20 (unrounded)
Denominator	ERP for one ore more five year age groups less than 30

The following age groups were used for calculating age standardised rates: 18-24, 25-29, 30-34, ..., 85+.

Computation:

100,000 x (Numerator ÷ Denominator), age standardised

Disaggregation:

Statistical Area Level 4, which have been derived from Postcode—Australian (person)

SA4s are designed for the output of labour force data and reflect labour markets within each state and territory within the population limits imposed by the Labour Force Survey sample. SA4s provide the best sub-state socio-economic breakdown in the ASGS.
SA4s are built from whole SA3s. Whole SA4s aggregate directly to state/territories in the ASGS Main Structure and greater capital city SAs. SA4s do not cross state/territory borders. There are 88 SA4 spatial units. In aggregate, they cover the whole of Australia without gaps or overlaps.
