In December 2017 the website Zimbabwe News, calculating the cost of the Mugabe era using various statistics, said that at the time of independence in 1980, the country was growing economically at about five per cent a year, and had done so for quite a long time. If this rate of growth had been maintained for the next 37 years, Zimbabwe would have in 2016 a GDP of US$52 billion. Instead it had a formal sector GDP of only US$14 billion, a cost of US$38 billion in lost growth. The population growth in 1980 was among the highest in Africa at about 3.5 per cent per annum, doubling every 21 years. Had this growth been maintained, the population would have been 31 million. Instead, as of 2018, it is about 13 million. The discrepancies were believed to be partly caused by death from starvation and disease, and partly due to decreased fertility. The life expectancy has halved, and death from politically motivated violence sponsored by government exceeds 200,000 since 1980. The Mugabe government has directly or indirectly caused the deaths of at least three million Zimbabweans in 37 years. According to World Food Programme, over two million people are facing starvation because of the recent droughts the country is going through.
