What Kiwis die of – Part II: The battle of the sexes

Two weeks ago , we asked Kiwis what they thought they would die of, and compared their responses to the primary causes of death recorded  by the Ministry of Health for the 29,204 people who died in New Zealand in 2009. Mike Dickison produced a beautiful infographic* of the causes that were responsible for more than 1% of those deaths. Obviously this data reflects what was recorded on the death certificate which may not always be the immediate cause of death. In fact, there was some discussion afterwards about the reality of ‘old age’ being an unacceptable cause of death here!
This week we decided to take a look at differences for causes of death recorded for men and women. Mike has worked his magic again and produced the infographic below. This time the little coffins each represent 25 people.
Its striking that more men die of prostate cancer than women die of ovarian, and twice as many men than women die from cancer of the bladder and kidney. But lots more women die of cerebrovascular diseases, that is strokes and brain haemorrhages, and dementia. To see if people’s perceptions tallied up with reality, we took to social media and asked people whether they thought there were any differences between what men and women died of**. So what did the Kiwis we surveyed think? Results are summarised in the slideshare presentation below.
The first striking thing to come from our survey participants is that the majority thought that more men die than women, and that more men die of diabetes, cerebrovascular diseases, traffic accidents and suicide. But not skin cancer. In actual fact, the numbers of men and women who died in 2009 was very similar, 14,615 men and 14,589 women. As you can see from the infographic, more men died in traffic accidents and diabetes, or committed suicide. But our respondents were way off with cerebrovascular diseases. And with the fact that skin cancer killed more men than women. The other question we asked related to breast cancer deaths in men. 8.2% of our respondents thought that men couldn’t get breast cancer. In fact, in New Zealand in 2009, 1 in 100 breast cancer deaths were in men.
As several people pointed out with our first infographic, these differences between perception and reality could be dangerous if they mean resources are diverted away from where they are really needed.

** We used Twitter, Facebook, and email to entice over 100 people to fill out our survey  using the SurveyMonkey website. Like all online surveys, ours should not be considered representative of the population of New Zealand, but rather of people on social media who were happy to fill out our survey.
This post is the second in a series inspired by the Guardian newspaper’s infographic ‘What we die of’  and is a collaboration between myself, chief number cruncher Dr Paul Gardner  and data visualisation extraordinaire Dr Mike Dickison . Dr Paul Gardner (@ppgardne) is a Royal Society of NZ Rutherford Discovery Fellow and Senior Lecturer in Bioinformatics at the University of Canterbury’s School of Biological Sciences. He gets very excited about RNA. Dr Mike Dickison (@adzebill) is a freelance information designer with a PhD on the evolution of giant flightless birds. He quite likes ukuleles too. Dr Siouxsie Wiles (@SiouxsieW) is a Health Research Council of NZ Hercus Fellow at the University of Auckland’s Faculty of Medical & Health Sciences. She is rather keen on nasty bacteria and anything that glows in the dark.
