collapse, although even prior to Somalia's state failure, data was often unreliable. The World Bank reports that Somalia's GDP was $917.0 million in 1990 and its total population was 13.42 million in 2014, and has since risen to 15 million as of 2018, marking roughly a 12% increase in its total population since then. In 2018 the World bank estimated an annual GDP of $6.2 billion, similar in size to Guam and the Kyrgyz Republic, and classifies it as a low-income country. The United Nations Statistics Division reports a GDP figure of $1.306 billion for 2012, compared to $2.316 billion in 2005 and $1.071 billion in 2010. According to the Central Bank of Somalia, sometime in the 2000s the country's GDP per capita according to the World Bank was $230, a slight reduction in real terms from 1990. The 2012 Human Development Report estimates per capita GDP to be $284, compared with an average across sub-Saharan Africa of $1,300 per capita. This GDP per capita figure is the fourth lowest in the world. About 43% of the population live on less than 1 US dollar a day, with about 24% of those found in urban areas and 54% living in rural areas. According to the United Nations Development Programme (UNDP) Somalia, the country had some of the lowest development indicators in the world, and a "strikingly low" Human Development Index (HDI) value of 0.285. This would rank amongst the lowest in the world if comparable data were available, and when adjusted for the significant inequality that exists in Somalia, its HDI is even lower. The UNDP notes that "inequalities across different social groups, a major driver of conflict, have been widening". The UN has classified Somalia as a least developed country since its Committee for Development Policy began categorising states in this way in 1971. An International Monetary Fund mission to Somalia reports estimated GDP growth of 3.7% in 2014 and CPI inflation of -71.10%. The report notes that provided that Somalia's security situation continues to improve modestly and there is no drought, economic growth in the medium term should average 5%, but that "growth will remain inadequate to redress poverty and gender disparities". An estimated 73% of the people of Somalia live below the poverty line in 2016. State failure and economic welfare According to the World Bank, within two years of the outbreak of civil war in 1988,
