The bar chart examines the number of households in the USA based on their yearly income for the years 2007, 2011, and 2015.
Overall, the chart shows that families earning around $100,000 consistently dominated during these periods, except in 2011 when the number of households with incomes between $25,000 and $49,999 was at its peak. Another significant point is that 2015 marked the year when US households across nearly all income categories experienced their highest earnings, with the only exception being households earning less than $25,000, which saw a gradual increase throughout all three periods.
Looking at the specifics, the category of households earning $100,000 and above accounted for just under 30 million in 2007, thereby dominating all other categories. In 2011, the number of families in this income bracket experienced a slight decline to about 28 million, but by 2015, the numbers rebounded to nearly 33 million households. Meanwhile, households earning between $25,000 and $49,999 fluctuated from 25 million to just under 30 million over the years, with this category peaking in 2011 at nearly 30 million households.
Similarly, there was a steady increase in the number of US families earning less than $25,000, rising from 25 million to almost 28 million by the end of the period. In contrast, the figures for families earning between $50,000 and $74,999 and those earning between $75,000 and $99,999 remained stable, accounting for only 21 million and just under 15 million households, respectively.
