The bar chart compares the data of American households according to their yearly income in 3 different years.
Overall, all the households in this country experienced an upward trend over the period, except for ones earning between $50,000 and $74,999, which remained the same. Notably, families earning from $75,000 to $99,999 a year consistently bottomed the list.
Households with yearly incomes of under $25,000 and from $25,000 to $49,999 displayed broadly similar trends, both increasing from about 25 million and 27 million initially to around 28 million and 30 million in 2011, respectively. However, by 2015, these figures had dropped negligibly to roughly 27 million for the under $25,000 category and 28 million for the other.
Similarly, high- income families exceeding $75,000 annually also saw growth. Despite a minor drop in 2011, households with $75,000 to $99,999 went up marginally by nearly a million to 15 million in 2015. Starting at around 29 million, families with over $100,000 also witnessed a drop of around 2 million to about 27 million in the middle year, but by 2015, this number had surged to approximately 33 million.
In contrast, with mid-level income homes ($50,000- $74,999), their numbers remained unchanged throughout the period at slightly over 20 million.
