The bar chart illustrates the number of households in the United States across four annual income categories for the years 2007, 2011, and 2015.
Households earning less than $25,000 were the largest group in 2007 and 2011, but by 2015, those earning $100,000 or more became the most numerous. Over time, there was a noticeable increase in high-income households, while THE lower-income groups experienced declines.
In 2007, households earning less than $25,000 were the most common, with around 30 million, but this figure steadily declined to approximately 25 million by 2015. Similarly, the $25,000–$49,999 category decreased from about 27 million in 2007 to just under 25 million in 2015. In contrast, the number of households earning $100,000 or more rose significantly, starting at 18 million in 2007 and peaking at over 30 million in 2015. The middle-income groups, $50,000–$74,999 and $75,000–$99,999, remained relatively stable, with slight fluctuations throughout the period.
