The bar chart presents the number of American households according to their annual revenue in three different years. Overall, while the number of people who earned less than 25,000, more than 25,000, and over 100,000 increased, the figures for those who earned between 50,000 and 100,000 stayed relatively stable over the 8-year period.
In detail, starting at around 25 million, the number of people who earned less than 25,000 rose to about 28 million in 2011, before declining to approximately 26 million in 2015. The figure for those who earned between 25,000 and 50,000 showed the similar patterns by rising from around 27 million in 2007 to nearly 30 million in 2011, before falling again to approximately 28 million. Similarly, those who possessed the highest amount of money, which was higher than 100,000 experienced an upward trend, beginning at almost 30 million in 2007, the number fell slightly to 27 million before peaking at about 33 million in the final year.
In contrast, the number of people who earned between 50,000 and 75,000 remained almost constant, standing at nearly 21 million in all three years. Following the similar pattern, those who earned more than 75,000, but less than 100,000 presented no significant changes, remaining at 14 billion throughout the years.
