By the end of this section, you will be able to:
  • Explain economic inequality and how the poverty line is determined
  • Analyze the U.S. poverty rate over time, noting its prevalence among different groups of citizens

Comparisons of high and low incomes raise two different issues: economic inequality and poverty    . Poverty is measured by the number of people who fall below a certain level of income—called the poverty line    —that defines the income needed for a basic standard of living. Income inequality compares the share of the total income (or wealth) in society that is received by different groups; for example, comparing the share of income received by the top 10% to the share of income received by the bottom 10%.

In the United States, the official definition of the poverty line traces back to a single person: Mollie Orshansky . In 1963, Orshansky, who was working for the Social Security Administration, published an article called “Children of the Poor” in a highly useful and dry-as-dust publication called the Social Security Bulletin . Orshansky’s idea was to define a poverty line based on the cost of a healthy diet.

Her previous job had been at the U.S. Department of Agriculture, where she had worked in an agency called the Bureau of Home Economics and Human Nutrition. One task of this bureau had been to calculate how much it would cost to feed a nutritionally adequate diet to a family. Orshansky found that the average family spent one-third of its income on food. She then proposed that the poverty line be the amount needed to buy a nutritionally adequate diet, given the size of the family, multiplied by three.

The current U.S. poverty line is essentially the same as the Orshansky poverty line, although the dollar amounts are adjusted each year to represent the same buying power over time. The U.S. poverty line in 2015 ranged from $11,790 for a single individual to $25,240 for a household of four people.

[link] shows the U.S. poverty rate    over time; that is, the percentage of the population below the poverty line in any given year. The poverty rate declined through the 1960s, rose in the early 1980s and early 1990s, but seems to have been slightly lower since the mid-1990s. However, in no year in the last four decades has the poverty rate been less than 11% of the U.S. population—that is, at best about one American in nine is below the poverty line. In recent years, the poverty rate appears to have peaked at 15.9% in 2011 before dropping to 14.5% in 2013. [link] compares poverty rates for different groups in 2011. As you will see when we delve further into these numbers, poverty rates are relatively low for whites, for the elderly, for the well-educated, and for male-headed households. Poverty rates for females, Hispanics, and African Americans are much higher than for whites. While Hispanics and African Americans have a higher percentage of individuals living in poverty than others, most people in the United States living below the poverty line are white.

In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

What is different between quantity demand and demand?
Shukri Reply
Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

The equation y = b + mx represents a linear equation in slope-intercept form, where y is the dependent variable, x is the independent variable, m is the slope, and b is the y-intercept. The slope-intercept form of a linear equation is commonly written as y = mx + b, where m represents the slope of
