The dramatic increase in the number of fatalities in organized violence, seen between 2011 and 2014, did not continue in 2015 and 2016. Rather, the notation of some 131,000 fatalities in 2014 was followed by a steep decline, with just below 119,000 in 2015 and a little over 102,000 fatalities in 2016. Despite the decrease, the number was the fifth highest during the entire 1989-2016 period. Most of the fatalities - over 87,000 - were incurred in state-based conflicts, the main driver behind the trend. Just as the number of fatalities, the number of state-based conflicts, albeit remaining on a high level, continued to decrease in 2016, going from 52 to 49, with 12 of them reaching the level of war, with at least 1,000 battle-related deaths. Also the non-state conflicts dropped in number in 2016, from 73 to 60. This was followed by a decrease in the number of fatalities, and only one conflict caused more than 1,000 deaths. Twenty-one actors were registered in one-sided violence, down by five from 2015. A number this low has only been recorded twice before; in both 2009 and 2010, 21 one-sided actors were listed in UCDP data. The number of fatalities also decreased, going from almost 9,800 to a little over 6,000.
