The bar chart illustrates the number of households in the United States according to their annual income throughout the years 2007, 2011, and 2015. Generally, the annual incomes of US households remained steady.

The proportion of households in the US with an annual income of roughly $50,000 to $75,000 remained steady throughout the three years, hovering around 20 million households from 2007 to 2015. Moreover, households that had an annual income of around $75,000 to $100,000 also remained stagnant. Throughout all three years, the number of households remained around 15 million.

Low-income households earning approximately $25,000 or less experienced a moderate increase from around 25 million in 2007 to 29 million in 2011, followed by a significant decline of approximately 2 million households in 2015. Similarly, households with an annual income between $25,000 and $50,000 saw a notable rise from 26 million in 2007 to around 30 million in 2011, before declining to approximately 27 million in 2025. In contrast, high-income households earning $100,00 or more annually showed a fluctuating trend, increasing from around 29 million in 2007 to 34 million in 2015, with variations during the intervening years.
