7.3 Newborn—unqualified days only

10.0 Hospital boarder

Presented as number of hospitalisations per 100,000 people.

Rates are directly age and sex standardised, to the 30 June 2001 Australian population aged 18 years and over, using 5-year age groups: 18-24, 25-29, … , 80-84, 85 and over.

Population estimates at 31 December are calculated as an average of the 30 June population estimates before and after the relevant December to derive a midpoint (31 December) population estimate. 

For more information about age-standardisation in general see glossary item Age-standardised rate. 

Analysis by state and territory is based on Statistical Area Level 2 (SA2) of usual residence of the patient.

Suppress data (number and rate) if at least one of the following conditions are met:

•  the total denominator is less than 1,000

•  the total numerator is less than 10

Age and sex standardised rates are also suppressed where the denominator for at least one of the age and sex groups used to calculate the rate is below 30.

Consequential suppression may be applied to preserve confidentialised data.
