The bar chart illustrates the number of households in the United States classified by their annual income in 2007, 2011, and 2015. The income groups range from less than $25,000 to over $100,000. Overall, the number of households in the US had a similar trend over the years.
In 2007, households earning $100,000 or more accounted for about 30 million, making it the largest group. However, this number decreased slightly in 2011 and further rose quite significantly by 2015 to around 33 million. In contrast, the proportion of households with income less than $25,000 million started at 25 million and experienced a gap of approximately 3 million by 2015.
Meanwhile, the number of households in the $25,000-$49,999, $50,000-$74,999, and $75,000-$99,999 income brackets showed relatively stable trends over the period, reaching around 28, 21, and 15 million, respectively, by 2015.
