Development aid is failing to improve the lives of the poorest 20 percent of the world's population, according to a report predicted growing global inequality. Poverty rates were halved under the United Nations Millennium Development Goals, which were adopted in 2000 and replaced in 2015 with 17 Sustainable Development Goals to end poverty, inequality and other global crises. However, the overall drop in poverty rates has been accompanied by a widening income gap between the most impoverished and the rest of the population, according to a report by Britain-based Development Initiatives.
