The US Census Bureau offers income data by household and individual. It is to be noted that 42% of households have two incomes earners; thus making households' income levels higher than personal income levels. The 2005 economic survey revealed the income distribution for households and individuals whereby the top 5% of individuals had six figure incomes (exceeding $100,000) and the top 10% of individuals had incomes exceeding $75,000. The top 5% of households, three quarters of whom had two income earners, had incomes of $166,200 or more, with the top 10% having incomes well in excess of $100,000. The top 1.5% of households had incomes exceeding $250,000 with 146,000 households, the top 0.12%, having incomes exceeding $1,600,000 annually. Households may also be differentiated among each other, depending on whether or not they have one or multiple income earners. While many middle-middle class households rely on two income earners to merely make ends meet, those in the upper middle class may be able to do so on just one income. In 2005 for example, the median households income for a two income earner households was $67,000. The median income for an individual employed full-time with a graduate degree was in excess of $60,000, concluding that nearly half of those with graduate degree are able to out-earn most dual income households with one-income.

Overall the term affluent may be applied to a variety of individuals, households or other entities depending on context. Data from the US Census Bureau serves as the main guideline for defining affluence. US government data not only reveals the nation's income distribution but also provides data regarding the demographic characteristics of those to whom the term, affluent, may be applied.

Top percentiles

Over time

Household income changes over the course of time, with income gains being substantially larger for the upper than for the lower percentiles. All areas of the income strata saw their incomes rise since the late 1960s, especially during the late 1990s. The overall increase in household income is largely the result of an increased percentage of households with more than one income earner. While households with just one income earner, most commonly the male, were the norm in the middle of the 20^th century, 42% of all households and the vast majority of married couple households now have two or more income earners. With so many present day households having two income earners, a substantial increase in household income is easy to explain.

Two income earner households are far more common among the top quintile of households than the general population. 2006 US Census Bureau data indicates that over three quarters, 76%, of households in the top quintile, with annual incomes exceeding $91,200, had two or more income earners compared to just 42% among the general population and a small minority in the bottom three quintiles. As a result much of the rising income inequity between the upper and lower percentiles can be explained through the increasing percentage of households with two or more incomes.

Median income levels

Professions

The vast majority of Americans derive the majority of their income from occupational earnings. Income derived from an occupation is largely determined by scarcity and the economic law of supply and demand. The more demand for a certain specialty and the less supply, the higher the income. There has been shown to be a correlation between increases in income and increases in worker satisfaction. The decrease in worker dissatisfaction, however, is not solely a result of the increase in income. Workers in more complex and higher level occupations tend to have attained higher levels of education and thus are more likely to have a greater degree of autonomy in the workplace. Additionally higher level workers with advanced degrees are hired to share their personal knowledge, to conceptualize, and to consult. Higher-level workers suffer less job alienation and reap not only external benefits in terms of income from their jobs, but also enjoy high levels of intrinsic motivation and satisfaction.

In the United States the highest earning occupational groups were white collar professionals including management. Individuals in these occupations tend to experience the highest job satisfaction and highest incomes. The overall highest paying profession in the United States is that of physician. Physician (M.D.and D.O.) compensation ranks as the highest median annual earnings of any profession. Median annual earnings ranged from $156,010 for family physicians to $321,686 for anesthesiologists. Surgeons post a median annual income of $282,504. By comparison the median annual salary for a Chief Executive Officer (C.E.O.) in May 2004 was $140,350. Overall annual earnings among the nation's top 25 professions ranged from the $70,000s to the $300,000s. In addition to physicians, lawyers, physicists, air traffic controllers, and nuclear engineers were all among the nation's 20 highest paid occupations with incomes in excess of $78,410. Some of the other occupations in the high five-figure range were economists with a median of $72,780, mathematicians with $81,240, financial managers with $81,880, and software publishers with median annual earnings of $73,060.

Education

Educational attainment plays a major factor in determining an individual's economic disposition. Personal income varied greatly according to an individual's education, as did household income. Incomes for those employed, full-time, year-round and over the age of twenty-five ranged from $20,826 ($17,422 if including those who worked part-time) for those with less than a ninth grade education to $100,000 for those with professional degrees ($82,473 if including those who work part-time). This median income for individuals with doctorates was $79,401 ($70,853 if including those who work part-time). These statistics reveal that the majority of those employed full-time with professional or doctoral degrees are among the overall top 10% (15% if including those who work part time) of income earners. Of those with a master's degree, nearly 50% were among the top quarter of income earners (top third if including those who work part time).

Race

Recent US Census Bureau publications indicate a strong correlation between race and affluence. In the top household income quintile, households with incomes exceeding $91,200, Whites and Asian Americans were overrepresented, whereas Hispanics and African Americans were underrepresented. The household income for Asian Americans was, at $61,094, by far the highest, exceeding that of Whites ($48,554) by 26%. Over a quarter, 27.5%, of Asian American households had incomes exceeding $100,000 , and another 40% had incomes of over $75,000. Among White households, who remained near the national median, 18.3% had six figure incomes, while 28.9% had incomes exceeding $75,000. The percentages of households with incomes exceeding $100,000 and $75,000 were far below the national medians for Hispanic and African American households. Among Hispanic households, for example, only 9% had six figure incomes, and 17% had incomes exceeding $75,000. The race gap remained when considering personal income. In 2005, roughly 11% of Asian Americans and 7% of White individuals had six figure incomes, compared to 2.6% among Hispanics and 2.3% among African Americans.

The racial breakdowns of income brackets further illustrate the racial disparities associated with affluence. in 2005, 81.8% of all 114 million households were White, 12.2% were African American, 10.9% were Hispanic and 3.7% were Asian American. While White households are always near the national median due to Whites being the by far most prevalent racial demographic, the percentages of minority households with incomes exceeding $100,000 strayed considerably from their percentage of the overall population. Asian Americans, who represent the smallest surveyed racial demographic in the overall population, were the found to be the prevalent minority among six figure income households. Among the nearly twenty million households with six figure incomes, 86.9% were White, 5.9% were Asian American, 5.6% were Hispanic and 5.5% were African American. Among the general individual population with earnings, 82.1% were White, 12.7% were Hispanic, 11.0% were African American and 4.6% were Asian American. Of the top 10% of income earners, those nearly 15 million individuals with incomes exceeding $77,500, Whites and Asians were once again overrepresented with the percentages of African Americans and Hispanics trailing behind considerably. Of the top 10% of earners, 86.7% were White. Asian Americans were the prevalent minority, constituting 6.8% of top 10% income earners, nearly twice the percentage of Asian Americans among the general population. Hispanics, who were the prevalent minority in the general population of income earners, constituted only 5.2% of those in the top 10%, with African Americans being the least represented with 5.1%.

Status and Stratification

It is important to remember that the above is an ideal type, a simplified model or reality using optimal circumstances. In reality other factors such as discrimination based on race, ethnicity and gender as well as aggressive political lobbying by certain professional organizations also influence personal income. An individual's personal career decisions as well as his or her personal connections within the nation's economic institutions are also likely to have an affect on income, status and whether or not an individual may be referred to as affluent. In contemporary America it is a combination of all these factors, with scarcity remaining the by far most prominent one, determine a person's economic compensation. Due to higher status professions requiring advanced and thus less commonly found skill sets (including the ability to supervise and work with a considerable autonomy) are better compensated through the means of income, making high status individuals relatively affluent, depending on reference group.

While the two paragraphs above only describe the relationship between status and personal income, household income is also often used to infer status. As a result, the dual income phenomenon presents yet another problem in equating affluence with high societal status. As mentioned earlier in the article 42% of households have two or more income earners, 76% of households with six figure incomes have two or more income earners. Furthermore people are most likely to marry their professional and societal equals. It therefore becomes apparent that the majority of households with incomes exceeding the six figure mark are the result of an economic as well as personal union between two economic equals. Today, two nurses, each making $55,000 a year, can easily outearn a single attorney who makes the median of $95,000 annually. Despite household income rising drastically through the union of two economic equals, neither individual has advanced his or her function and position within society. Yet the household (not individual) may have become more affluent, assuming an increase in household members does not off-set the dual-income derived gains.
