Territory controlled by Islamic State (IS or Daesh) shrunk by 23% in 2016, according to analysis by IHS Markit, from 78,000km2 in early January 2016 to 60,400km2 by the end of the year. As of January 2015, the ‘caliphate’ had controlled some 90,800km2 of territory. Continued progress by Iraqi government forces in eastern parts of Mosul, along with advances by the Hashd Al-Shaabi (Popular Mobilisation Forces) to the west of the city which are preventing resupply for IS fighters, prompted IHS to predict that Daesh will lose control of the city by mid-year.
