In 1820, there were nearly 1,1 billion people in the world, of whom more than 1 billion lived in extreme poverty (under 1.90 dollars a day). Since about 1970, we live in a world where the number of non-poor people is increasing, while the number of poor people is falling significantly. 1970 2,2 billion people lived in extreme poverty, 2015 it was still 705 million, about eight percent of the world's population. UN forecasts show a further drop to around four percent in the year 2030.
