The bar chart presents data on the yearly income of households in the United States over an eight-year period.
Overall, the proportion of households earning between $50,000 and $99,999 remained relatively stable, while the lowest and highest income, less than $49,999 and $100,000, respectively, experienced upward trends.
It is clear that the households that were earning between $25,000 and $49,999 flatulated throughout the years, with nearly 27 million and 30 million households receiving $25,000-$49,999 in 2007 and 2011, respectively. However, by 2015, the number decreased to about 28 million households. For families who obtained annual incomes of $50,000 and $74,999, there was no noticeable change but stayed constant from 2007 to 2015. Similarly, salaries between $75,000 and $99,999 saw a slight growth during the surveyed period, with a slight dip in 2011 at about 18 million.
Conversely, there were 25 million and almost 30 million households earning less than $25,000 in 2007 and 2011, respectively, but by 2015, there was a slight decrease to 28 million. In addition, the highest income group ($100,000 or more) had the most significant change, climbing from nearly 30 million in 2007 to a peak of approximately 34 million, despite a slight fall in 2011.
