After Adam and I wrote articles about having to be careful when interpreting data, this Toronto Police graph came to my attention. It’s part of their ‘Way Forward’ initiative, already covered, that seeks input from Toronto residents about the future of policing.
The chart is breathtaking in its deceptiveness and misrepresents the true levels of crime in these cities. The authors seem to want people to interpret the graph to the effect that New York City, Los Angeles and Chicago have lower crime levels than Toronto. The fine print at the bottom basically informs readers that the statistics are meaningless but who cares, the bars have probably done their job.
For those interested, and again, murder being the best indicator of violent crime levels since there’s no ambiguity about a murder – they are almost always reported, here are the same cities’ murder rates in 2013, the middle year used in the police chart, so we can compare apples to apples.
