Extreme poverty refers to a situation where individuals or households lack the basic necessities for survival, such as access to food, clean water, shelter and healthcare. It is often characterized by extreme deprivation, malnutrition, disease, and limited opportunities for education and employment. People living in extreme poverty are at a higher risk of experiencing social exclusion, human rights violations, and other forms of suffering. The United Nations has set an international standard to measure extreme poverty, which is defined as living on less than $1.90 per day (in 2011 prices). According to the World Bank, in 2015, approximately 836 million people lived below this poverty line, with the majority of them residing in South Asia and sub-Saharan Africa.
