World Bank estimates indicate that the number of people living in extreme poverty (defined as living on less than $1.25 a day at the time) decreased from approximately 1.5 billion in 1981 to about 1 billion by 2004. This decline is largely attributed to rapid economic growth in developing nations, particularly in East Asia, which lifted millions out of absolute poverty.

The absolute poverty line represents a fixed standard of living, usually calculated based on the cost of basic necessities such as food, clothing, and shelter required for physical survival. Unlike relative poverty, which compares an individual's income to the average standard of living in their society, absolute poverty is an objective measure of the resources needed to sustain life.

Absolute poverty refers to a condition where household income is below a necessary level to maintain basic living standards, such as food, shelter, and clothing. Unlike relative poverty, which compares an individual's economic status to the average in their society, absolute poverty is a fixed standard based on the minimum requirements for human survival, regardless of the broader economic context.

The absolute poverty line is a fixed threshold based on the minimum amount of income required to purchase basic necessities such as food, clothing, and shelter. Unlike relative poverty, which compares individuals to the societal average, absolute poverty focuses on the physical survival of the individual regardless of the broader economic context.

Absolute poverty is a condition where household income is below a necessary level to maintain basic living standards (food, shelter, housing). By using a consistent metric, sociologists can compare poverty levels across different countries to assess global economic disparities, even though purchasing power may vary.

The market model of social policy prioritizes individual responsibility, where the majority of the population is expected to purchase welfare services, such as health insurance, privately. State involvement is restricted to providing a basic safety net through means-tested benefits for those in significant financial need. This contrasts with the welfare state model, which advocates for universal access to services regardless of an individual's income level.

Esping-Andersen categorized welfare states into three distinct 'worlds': liberal, conservative, and social democratic. The social democratic model, prevalent in Nordic countries, emphasizes universalism, high levels of social solidarity, and extensive public sector involvement to ensure equality. This approach contrasts with the liberal model's focus on market-based solutions and the conservative model's reliance on traditional social insurance structures.

AARP stands for the American Association of Retired Persons. It is a major interest group in the United States that focuses on issues affecting those over the age of 50, providing advocacy, information, and services to its members regarding retirement, health, and social security.

The 'residual' model of welfare, often associated with liberal welfare regimes, posits that the state should only intervene when the family or the market fails to provide for an individual. It is a means-tested approach designed to provide a minimal safety net for the most vulnerable, rather than providing universal coverage to all citizens.

The market model of welfare emphasizes individual responsibility and the privatization of social services. Under this framework, the state reduces its direct role, encouraging citizens to purchase welfare services through private markets, while providing only minimal, means-tested safety nets for those unable to participate in the market, thereby shifting the burden from the state to the individual.
