The provided bar graph displays the distribution of households in the US based on their annual income for the years 2007, 2011, and 2015.
Overall, the data illustrates a slight increase in the number of households with annual incomes below $49,999 and a decrease in households with annual incomes between $50,000 and $99,999. Conversely, there was a significant rise in the number of households earning $100,000 or more, with 2015 showing the highest count in this category.
In 2007, there were approximately 43 million households with an annual income of less than $35,000, which increased slightly to nearly 45 million in 2011 before decreasing to slightly over 42 million in 2015. The $35,000-$49,999 income category saw a decrease from around 25 million households in 2007 to close to 20 million households in 2015. In contrast, the $50,000-$74,999 income group had around 28 million households in 2007, almost 27 million in 2011, and close to 25 million in 2015. Finally, the $75,000-and-over income group exhibited an increase from about 35 million households in 2007 to nearly 45 million in 2015.
The number of households with an annual income between $50,000 and $99,999 was substantially lower with 20 million and 14 million households in 2007. This group remained relatively consistent in the following years, ultimately reaching 21 million households earning between $50,000 and $74,999 and 15 million households earning between $75,000 and $99,999 in 2015. The highest income group of $100,000 or more experienced significant changes over the 8-year period, increasing from 29 million households in 2007 to around 34 million households in 2015.
