2009 and 2010 DUMA findings: Site results

In this section, results are presented from self-report and urinalysis data for each of the nine DUMA sites separately. In 2009 and 2010, these sites included Adelaide, Bankstown, Brisbane, Darwin, Footscray, East Perth, Kings Cross, Parramatta and Southport. Data collection at the Kings Cross and Parramatta sites alternate on a quarterly basis, so data was collected at Kings Cross during quarters 1 and 3 and at Parramatta in quarters 2 and 4 in both years. It should be noted that these sites vary in catchment area population size as well as the sample size obtained for DUMA.

The Tables for each site include detailed data on drug use and offending behaviour, socio-demographics, drug treatment and drug attribution. The data on drug use examines detainees who tested positive by gender, drug type, age, most serious offence and other drug-related behaviour. Results are also presented on self-reported drug use, focusing on gender, drug type and age.

Methodological note

When interpreting the site-based results presented in these chapters, readers should be reminded of the following methodological notes:

  • The police process fewer female detainees than male detainees. Accordingly, the sample size for this group is much smaller and this should be kept in mind when considering data for female detainees disaggregated at the site level.
  • In some cases the column percentages may not total 100 due to rounding or because multiple responses were permitted across a range of response options.
  • Missing data have been excluded from the analysis, which means that sample sizes may vary slightly throughout each section.
  • The any drug category refers to detainees who tested positive to any of the following drugs: methamphetamine, benzodiazepines, cannabis, cocaine or heroin.
  • Multiple drug use refers to those detainees who tested positive to two or more of the following drugs: methamphetamine, benzodiazepines, cannabis, cocaine or heroin.
  • Throughout the 13 years of DUMA’s operation, a number of changes have been made to both the methodology and annual reporting. These changes have been made to improve the reliability and accuracy of the data and to ensure the relevance of the DUMA data to key stakeholders. This report and the trend data presented within it represent the most up-to-date information from the DUMA program. Direct comparisons with earlier annual reports should be undertaken with this in mind.
