Poverty is the state of not having enough material possessions or income for a person's basic needs. Poverty may include social, economic, and political elements. Absolute poverty measures compare income against the amount needed to meet basic personal needs, such as food, clothing, and shelter. Relative poverty measures when a person cannot meet a minimum level of living standards, compared to others in the same time and place. Therefore, the floor at which relative poverty is defined varies from one country to another, or from one society to another.As of 2019, most people on the planet live in poverty: (in Purchasing Power Parity dollars) 85% 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 (extreme poverty).Many governments and non-governmental organizations try to reduce poverty by providing basic needs to people who are unable to earn a sufficient income. These efforts can be hampered by constraints on government's ability to deliver services, such as corruption, tax avoidance, debt and loan conditionalities and by the brain drain of health care and educational professionals. Strategies of increasing income to make basic needs more affordable typically include welfare, economic freedoms and providing financial services. Meanwhile, the poorest citizens of middle-income countries have largely failed to receive an adequate share of their countries’ increased wealth.Effectiveness is the capability of producing a desired result or the ability to produce desired output. When something is deemed effective, it means it has an intended or expected outcome, or produces a deep, vivid impression.
