Measure c(2i): Number of users of open employment services aged 15-64 years in the reporting period divided by estimated potential population for employment services (people aged 15-64 years with profound or severe core activity limitation) on 30 June at the start of the reporting period.

Measure c(2ii): Number of users of supported employment services aged 15-64 years in the reporting period divided by estimated potential population for employment services (people aged 15-64 years with profound or severe core activity limitation) on 30 June at the start of the reporting period.

R/N x 100

where

R = number of disability employment service users aged 15–64 years in the reporting period and

N = estimated potential population for employment services (people aged 0-64 years with profound or severe core activity limitation) on 30 June at the start of the reporting period

For measures disaggregated by need for assistance in life area, N = the state/territory total of the number of service users in the reporting period.

Measure c(2i): Number of users of open employment services aged 15-64 years in the reporting period.

Measure c(2ii): Number of users of supported employment services aged 15-64 years in the reporting period.

Estimated potential population for employment services (people aged 15-64 years with profound or severe core activity limitation) on 30 June at start of reporting period.

Potential population will be calculated by applying age-sex specific rates of severe/profound core activity limitation (from the 2009 Survey of Disability, Ageing and Carers (SDAC 2009)) to the 30 June 2009 Estimated Residential Population by state/territory by age group by sex. No Indigenous weight or scaling factor is used.

National level age-sex rates, rather than state/territory-age-sex rates have been used previously due to the high sampling errors associated with some of the state/territory-age-sex rate estimates in SDAC 2003 and previous iterations of the survey.   National level rates will be used from SDAC 2009 to calculate the potential population for this reporting cycle.  A complete review of the data sources and methods used for the calculation of potential population for National Agreement performance reporting will be undertaken by the Potential Population Working Group on behalf of the DPRWG, however the results of this review will not be available for this reporting cycle.

The method used to calculate the country of birth and remoteness disaggregation's will be the same as that adopted by the Disability Services Working Group for calculation of special needs group indicators in the Report on Government Services 2012. This method incorporates 2006 Census data for comparing population groups.

Measures disaggregated by 'need for assistance in life' area will not use potential population as the denominator.  The denominator for these measures will be the state/territory total of the number of service users in the reporting period.

For measure c(2i) (service type 5.01) and measure c(2ii) (service type 5.02):

• State/territory by sex (male, female, total) by age group (15–24, 25–34, 35–44,45–54, 55–64 years, total)
• Country of birth (Australia, other English speaking countries, all English speaking countries, non-English speaking countries, total)
• Remoteness Area (Major Cities, Inner Regional, other, total)
• State/territory by need for assistance (activities of daily living, activities of independent living or work, education or community but not activities of daily living, total needing assistance, no need for help or supervision, level of assistance not determined, total)
  

AIHW to produce indicators

The AIHW will conduct an investigation into the feasibility and data quality of attaching SEIFA to the DS NMDS.

A complete review of the data sources and methods used for the calculation of potential population for National Agreement performance will be undertaken by the Potential Population Working Group on behalf of the DPRWG.

Classifications proposed above are appropriate for the current CSTDA/DS NMDS. Classifications will need to be reviewed in line with any future changes to the NMDS.

Available disaggregation depends on sampling errors and other caveats.

Cells with numerator counts less than 5 will be suppressed.

For measure c(2i) and c(2ii), people with age reported in the range 15 to 64 years only are included in calculations. People with age reported to be 65 years or older are not included.

Treatment of ‘not stated’ values within disaggregation's (numerator only):

• Age group: Only people with known age will be included.
• Sex: Total includes people with ‘not stated’ sex.
• Country of birth: All English speaking countries is the subtotal of Australia and other English speaking countries. Total includes people with ‘not stated’ country of birth.
• Remoteness: Outer Regional/Remote includes Outer Regional, Remote and Very Remote. Total includes people where remoteness area cannot be determined.
• Need for assistance: Total needing assistance includes need for assistance in activities of daily living, activities of independent living and activities of work, education or community. Total includes service users with level of assistance not determined.

Caution is recommended in the use or interpretation of performance at service group level.  There is a risk when the service group level data is interpreted in isolation as various service groups are complementary and the emphasis on different services reflects jurisdictional policy directions.  Potential population estimates in these tables are not necessarily specific to the individual service group.
