Off topic-What we believe vs Census data

Found a very interesting web page with charts showing deaths worldwide from various causes.I was actually searching for Gun and Alcohol,terrorist related deaths to get some facts about gun control and was very surprised to see what we should really be concerned about.Just scroll down to the charts and let me know what you think.

Another interpretation of the charts.

Looks like near on all South Africans are likely to be Aids carriers.

There is almost zero homosexuality in Iraq. I wonder why considering that homosexuality is common world wide

Heart disease causes most deaths world wide. With cancer a close second.

Interesting tables.

I looked at suicide compared to road incidents. We spend a lot of attention/government advertising on road deaths and to my mind, perhaps not enough on suicide. China's road incidents is something to have a look at compared to other countries and the average. Suicide in Russia is quite high. The other notable one for me is the higher rate of cancer deaths in Canada compared to cardio-vascular disease.

I doubt the accuracy of those charts because there are millions of people in third world countries who die without ever being diagnosed by a doctor because they cannot afford a doctor or are no where near one.
