The Economic Policy Institute (EPI) estimated that greater income inequality added 5.5% to the poverty rate between 1979 and 2007, other factors equal. Income inequality was the largest driver of the change in the poverty rate, with economic growth, family structure, education and race other important factors.
Economic inequality is an umbrella term for a) income inequality or distribution of income (how the total sum of money paid to people is distributed among them), b) wealth inequality or distribution of wealth (how the total sum of wealth owned by people is distributed among the owners), and c) consumption inequality (how the total sum of money spent by people is distributed among the spenders).
The relationship between poverty reduction and differing levels of welfare expense as a percentage of GDP [1] The effects of social welfare on poverty have been the subject of various studies. [1] Studies have shown that in welfare states, poverty decreases after countries adopt welfare programs. [2]
The main poverty line used in the OECD and the European Union is a relative poverty measure based on 60% of the median household income. The United States uses an absolute poverty measure based on the U.S. Department of Agriculture's "economy food plan", adjusted for inflation. The World Bank also defines poverty in absolute terms.
The model describes that a change in inequality affects absolute poverty in two ways. First, a change in relative poverty affects absolute poverty by immediately changing the number of people below the poverty line. Second, a change in relative poverty changes the growth elasticity of poverty. A redistribution of income means more poverty ...
While such ratios do not represent the overall level of inequality in the population as a whole, they provide measures of the shape of income distribution. For example, the attached graph shows that in the period 1967–2003, US income ratio between median and 10th and 20th percentile did not change significantly, while the ratio between the ...
The poverty gap index ignores the effect of inequality between the poor. It does not capture differences in the severity of poverty amongst the poor. As a theoretical example, consider two small neighborhoods where just two households each are below the official poverty line of US$500 income per year.
The social determinants of health in poverty describe the factors that affect impoverished populations' health and health inequality. Inequalities in health stem from the conditions of people's lives, including living conditions , work environment, age , and other social factors, and how these affect people's ability to respond to illness .
