  According to Chen and Ravallion, about 1.76 billion people in the developing world lived above $1.25 per day and 1.9 billion people lived below $1.25 per day in 1981. In 2005, about 4.09 billion people in the developing world lived above $1.25 per day and 1.4 billion people lived below $1.25 per day (both 1981 and 2005 data are on inflation adjusted basis). The share of the world's population living in absolute poverty fell from 43% in 1981 to 14% in 2011. The absolute number of people in poverty fell from 1.95 billion in 1981 to 1.01 billion in 2011. The economist Max Roser estimates that the number of people in poverty is therefore roughly the same as 200 years ago. This is the case since the world population was just little more than 1 billion in 1820 and the majority (84% to 94%) of the world population was living in poverty.
  
  According to one study, the percentage of the world population in hunger and poverty fell in absolute percentage terms from 50% in 1950 to 30% in 1970. According to another study the number of people worldwide living in absolute poverty fell from 1.18 billion in 1950 to 1.04 billion in 1977. According to another study, the number of people worldwide estimated to be starving fell from almost 920 million in 1971 to below 797 million in 1997. The proportion of the developing world 's population living in extreme economic poverty fell from 28% in 1990 to 21% in 2001. Most of this improvement has occurred in East and South Asia.
  
  In 2012 it was estimated that, using a poverty line of $1.25 a day, 1.2 billion people lived in poverty. Given the current economic model, built on GDP, it would take 100 years to bring the world's poorest up to the poverty line of $1.25 a day. UNICEF estimates half the world's children (or 1.1 billion) live in poverty. The World Bank forecasted in 2015 that 702.1 million people were living in extreme poverty, down from 1.75 billion in 1990. Extreme poverty is observed in all parts of the world, including developed economies. Of the 2015 population, about 347.1 million people (35.2%) lived in Sub-Saharan Africa and 231.3 million (13.5%) lived in South Asia. According to the World Bank, between 1990 and 2015, the percentage of the world's population living in extreme poverty fell from 37.1% to 9.6%, falling below 10% for the first time.
  
  During the 2013 to 2015 period, the World Bank reported that extreme poverty fell from 11% to 10%, however they also noted that the rate of decline had slowed by nearly half from the 25 year average with parts of sub-saharan Africa returning to early 2000 levels. The World Bank attributed this to increasing violence following the Arab Spring, population increases in Sub-Saharan Africa, and general African inflationary pressures and economic malaise were the primary drivers for this slow down. Many wealthy nations have seen an increase in relative poverty rates ever since the Great Recession, in particular among children from impoverished families who often reside in substandard housing and find educational opportunities out of reach. It has been argued by some academics that the neoliberal policies promoted by global financial institutions such as the IMF and the World Bank are actually exacerbating both inequality and poverty.
  
  In East Asia the World Bank reported that "The poverty headcount rate at the $2-a-day level is estimated to have fallen to about 27 percent, down from 29.5 percent in 2006 and 69 percent in 1990." The People's Republic of China accounts for over three quarters of global poverty reduction from 1990 to 2005, which according to the World Bank is "historically unprecedented". China accounted for nearly half of all extreme poverty in 1990.
  
  In Sub-Saharan Africa extreme poverty went up from 41% in 1981 to 46% in 2001, which combined with growing population increased the number of people living in extreme poverty from 231 million to 318 million. Statistics of 2018 shows population living in extreme conditions has declined by more than 1 billion in the last 25 years. As per the report published by the world bank on 19 September 2018 world poverty falls below 750 million.
  
  In the early 1990s some of the transition economies of Central and Eastern Europe and Central Asia experienced a sharp drop in income. The collapse of the Soviet Union resulted in large declines in GDP per capita, of about 30 to 35% between 1990 and the through year of 1998 (when it was at its minimum). As a result, poverty rates tripled, excess mortality increased, and life expectancy declined. Russian President Boris Yeltsin 's IMF -backed rapid privatization and austerity policies resulted in unemployment rising to double digits and half the Russian population falling into destitution by the early to mid 1990s. By 1999, during the peak of the poverty crisis, 191 million people were living on less than $5.50 a day. In subsequent years as per capita incomes recovered the poverty rate dropped from 31.4% of the population to 19.6%. The average post-communist country had returned to 1989 levels of per-capita GDP by 2005, although as of 2015 some are still far behind that. According to the World Bank in 2014, around 80 million people were still living on less than $5.00 a day.
  
  World Bank data shows that the percentage of the population living in households with consumption or income per person below the poverty line has decreased in each region of the world except Middle East and North Africa since 1990:
  
  In July 2023, a group of over 200 economists from 67 countries, including Jayati Ghosh, Joseph Stiglitz and Thomas Piketty, sent a letter to the United Nations secretary general António Guterres and World Bank president Ajay Banga warning that "extreme poverty and extreme wealth have risen sharply and simultaneously for the first time in 25 years." In 2024, Oxfam reported that roughly five billion people have become poorer since 2020 and warned that current trends could postpone global poverty eradication for 229 years.
