New crime map reveals Perth crime hot spots

Perth Crime Map uses population records from the 2011 census and WA Police crime report statistics in order to determine the number of crimes per 100 residents.

The map is based on the previous year of crime statistics released by WA Police, and continues to update every three months.

Creator Nick Lilleymen said he began working on the map when a friend moved to the southern suburb of Willetton.

"Straight after moving in, he fitted his house out with all types of security and fancy CCTV systems," he said.

"I thought this was total overkill considering how safe I believed Willetton to be. I searched for an online map or tool to prove how safe Willetton is relative to other suburbs, but couldn't find anything of any value and figured I could make one myself."

The website has since flagged the eastern suburb of Midvale as WA's worst offender, at 15.9 crimes per 100 residents.

The suburb was closely followed by Burswood, Perth CBD, Midland and Mandurah.

Armadale recorded the most instances of assault and car theft, while Mandurah recorded the highest number of robbery reports.

In contrast, Dalkeith, Floreat, Leeming and Duncraig recorded the least crime per 100 people.

While Dalkeith shared a similar population with Osborne Park, Dalkeith had only experienced 7 assaults, 21 burglarys, 3 car thefts and no recorded instances of robbery or graffiti.

Meanwhile Osborne Park recorded 105 assaults, 181 burglarys, 9 robberies, 40 car thefts and 9 reports of graffiti.

The website will again update when 2016 census figures are released.

Mr Lilleyman said he hoped WA Police would engage more analytical tools when organising the distribution of police resources.

"The police could look at long term trends across suburbs or even spikes in recent months to understand hotspots," he said.

Mr Lilleyman said areas such as Perth CBD, Fremantle and Burswood seemed to be over-represented in the data.

"Entertainment districts look much worse than they probably are, as they often have very few residents, but lots of foot traffic and drinking- hence their very high crime rates," he added.

Fremantle has experienced a spate of high profile incidents in recent months, after an 18 year old boy was stabbed by a relative in the area, and a one-punch attack left another man in a critical condition.
