the chart below shows the number of households in the US by their annual income in 2007 2011 and 2015

The bar chart illustrates the quantity of households in America categorized by their cash that they earned per year among three years: 2007, 2011 and 2015.
There were 15 million households had income in range of $75000 to $99999 which were stable and also the lowest figure throughout the period. In contrast, the number of families who had over $100000 annually was nearly 30 million in 2007 then increased significantly to 34 million after a slight fall in 2011.
In addition, the amount of middle level seems to be not changed over the years while the same trend was been recorded in the change of people who had less than $25000 and $25000-$49999 yearly. The figures for households who have lowest income and double of this start at 25 and 26 million in 2007 then reached a peak in 2011 and decreased slightly to 26 and 27 million, respectively in the last year of the term.
Overall, across 8 years, it is evident that there is no clear trend in the number of households across various income brackets. Besides that, most of the figures have a tiny change through the period.
