They take into account all the wars fought throughout human history and just the sheer number of people killed violently during the 20th century, which had seen rapid growth in population. I think it came from a guy disputing religion as the chief cause of violent deaths (I studied international affairs and we also came to the same conclusion, but that had more to do with the actual cause of wars and not using excuses such as religious/ethnic differences), but his research was pretty academically grounded.
The 20th century just saw extremely destructive ways of killing one another that were not seen in prior wars. A tribe here or there being wiped out is small. I live in a small city in San Diego (population 23,000), and you could wipe out tens thousands of tribes given our population.

But if we walk in the light, as He is in the light, we have fellowship with one another, and the blood of Jesus, His Son, purifies us from all sin.
