The tendency for international news to focus on violent conflict makes it hard not to conclude that the world is getting more dangerous.

But a growing body of evidence suggests the opposite is the case.

Harvard Professor Steven Pinker charted the pacification of human society from pre-history to the 20th Century in The Better Angels of Our Nature and found death rates from conflict falling from 15% per annum to 3%.

Now Oxford University economist Max Roser has charted the available statistics on conflict since 1400 on OurWorldInData.

The chart uses a logarithmic scale for deaths, which means the reduction in conflict mortality rates in the 20th Century is sharper than it appears at first sight.
