The bar chart compares the number of households in the United States across five income categories in the years 2007, 2011, and 2015.
Overall, households earning $100,000 or more were the most common group in all three years, and this category showed a noticeable increase by 2015. In contrast, the number of households in the middle-income ranges remained relatively stable, while the lowest income group experienced some fluctuations.
In 2007, around 25 million households earned less than $25,000, while approximately 27 million were in the $25,000-$49,999 category. The number of households earning $50,000-$74,999 was lower, at about 20 million, and even fewer households earned $75,000-$99,999, at roughly 15 million. The highest income group, those earning $100,000 or more, accounted for just under 30 million households.
In 2011, the figures for the lower and middle-income groups showed slight changes. The lowest income category rose marginally, while the $50,000-$74,999 group decreased a little. Meanwhile, the number of high-income households dropped slightly compared to 2007.
By 2015, there was a clear increase in households earning $100,000 or more, reaching just over 30 million, the highest figure on the chart. Other income groups showed only minor changes, with most remaining close to their previous levels
