The bar chart presents data on the annual income of households in the United States over an eight-year period from 2007 to 2015.
Overall, the proportion of households earning between $50,000 and $99,999 remained relatively stable, while both the lowest income category (under $25,000) and the highest income category ($100,000 or more) showed upward trends.
Households earning between $25,000 and $49,999 fluctuated throughout these years, with nearly 27 million households in this range in 2007, rising to 30 million in 2011, before decreasing to about 28 million by 2015. For households earning between $50,000 and $74,999, there was little to no change over the period, with figures remaining relatively constant. Likewise, households in the $75,000 to $99,999 range experienced a slight increase, though there was a minor dip in 2011 at around 18 million.
In contrast, the number of households with an income of less than $25,000 increased from 25 million in 2007 to nearly 30 million in 2011, followed by a slight decrease to 28 million in 2015. The highest income group, earning $100,000 or more, showed the most significant growth, climbing from nearly 30 million in 2007 to approximately 34 million in 2015, despite a slight decline in 2011.
