Answer:
It would be wrong to believe that the past was peaceful. One reason why some people might have this impression is that many of the past conflicts feature less prominently in our memories; they are simply forgotten.The absolute number of war deaths has been declining since 1946. In some years in the early post-war era, around half a million people died through direct violence in wars; in contrast, in 2016 the number of all battle-related deaths in conflicts involving at least one state was 87,432.
The decline of the absolute number of battle deaths can be seen in the visualization here that shows global battle deaths per year by world region. There are three marked peaks in war deaths since then: the Korean War (early 1950s), the Vietnam War (around 1970), and the Iran-Iraq and Afghanistan wars (1980s). There has been a recent increase in battle deaths driven by conflict in the Middle East, particularly in Syria, Iraq and Afghanistan.
To answer the question of how many people die in conflicts today, and how this has changed over time, we can turn to a number of different datasets.
Here we show the world conflict death rate since 1989 according to five sources.
There are certainly similarities across the different sources. Overall they show a decline in conflict deaths into the 2000s, followed by an increase this decade.5
But there are also large differences. Most noticeably, there is a large jump in 1994 – marking the Rwandan genocide – which is present in some series, but absent from others.
If you look closely, you’ll see that there are large relative differences between the series over the entire period as well, though they are understated by the 1994 peak. If you hover over the datapoints, you can see the exact figures: the highest figure for a given year is typically well more than double the lowest
