The bar chart illustrates the number of America’s households measured in 5 diverse ranges of yearly revenue with dollars as the unit, starting from less than $25,000 to $100,000 and more. This graph also shows the variety of the numbers in 3 different years: 2007, 2011, and 2015.
Overall, the lowest number of the families are those who earned $75,000 – $99,999, while the tier is led by the highest income itself, with the exception of 2011, which was true for those making $25,000-$49,999.
In 2007, households earning more than $100,000 were recorded to be at the top of the list, just slightly lower than 30 million. The chart then drops to around 27-28 million before peaking with 6-7 million additions in 2015. Moreover, those who obtained under $50,000 experienced fluctuations at the range between 25 to just short of 30 million, and ended up in 27-28 million.
On the other hand, the proportion of households earning about $50,000 – $74,999 appears to have its stability at more than 20 million in an 8-year period. Furthermore, the second highest earning families are shown to be having a minimal rise, ending up at exactly 15 million on the chart.
