Anna Stewart, James Ogilvie and Troy Allard
Workshop presentation 11 July 20082
Background• Queensland fastest growing state in Australia
– Between 2001 and 2006 10% increase in population to just over 4 million people– Expected to double in next 40 years– Hospitals, water, roads and public transport– Increase in 25 to 30 year old couples
• Key growth factor is natural resources– Coal, gas, minerals (copper, lead, zinc, gold and silver), petroleum – China demand for commodities
• Government focus on infrastructure – 1.6 million dollars every hour spent on infrastructure
• Little or no focus of the impact of growth on crime
Workshop presentation 11 July 20083
Research Questions
• What is the impact of this growth on crime?
• Data– ABS 2001 and 2006 census data by SLA
– QPS 2001 and 2006 reported crime data by SLA
Workshop presentation 11 July 20084
Profile of the population growth• 2001 and 2006 ABS census data• Queensland divided into 479 Statistical Local Areas (SLA)• 2006 mean population 8,495 (SD = 8,495)
– Min population = 66– Max population = 72,683
• 2001 to 2006 mean population growth 822.77 (SD = 1,497.9)– Min growth = - 856– Max growth = 10,856 (increase of 69%)
Workshop presentation 11 July 20088
Remoteness areas• Major Cities (N = 256)
– Highest population growth• Inner Regional (N = 60)
– Highest total population– High population growth
• Outer Regional (N = 77)• Remote (N = 28)• Very Remote (N = 57)
– No growth• Migratory (N = 2)
