Poverty is a state or condition in which a person lacks the financial resources and essentials for a certain standard of living. Poverty can have diverse social, economic, and political causes and effects.[1] When evaluating poverty in statistics or economics there are two main measures: absolute poverty compares income against the amount needed to meet basic personal needs, such as food, clothing, and shelter;[2] relative poverty measures when a person cannot meet a minimum level of living standards, compared to others in the same time and place. The definition of relative poverty varies from one country to another, or from one society to another.[2]

Statistically, as of 2019, most of the world's population live in poverty: in PPP dollars, 85% of people live on less than $30 per day, two-thirds live on less than $10 per day, and 10% live on less than $1.90 per day now changed to 2.15$/day.(extreme poverty).[3] According to the World Bank Group in 2020, more than 40% of the poor live in conflict-affected countries.[4] Even when countries experience economic development, the poorest citizens of middle-income countries frequently do not gain an adequate share of their countries' increased wealth to leave poverty.[5] Governments and non-governmental organizations have experimented with a number of different policies and programs for poverty alleviation, such as electrification in rural areas or housing first policies in urban areas. The international policy frameworks for poverty alleviation, established by the United Nations in 2015, are summarized in Sustainable Development Goal 1: "No Poverty".

Social forces, such as gender, disability, race and ethnicity, can exacerbate issues of poverty—with women, children and minorities frequently bearing unequal burdens of poverty. Moreover, impoverished individuals are more vulnerable to the effects of other social issues, such as the environmental effects of industryor the impacts of climate change or other natural disasters or extreme weather events. Poverty can also make other social problemsworse; economic pressures on impoverished communities frequently play a part in deforestation, biodiversity loss and ethnic conflict. For this reason, the UN's Sustainable Development Goals and other international policy programs, such as the international recovery from COVID-19, emphasize the connection of poverty alleviation with other societal goals.[6]
