The visual illustrates the amount of households in the US by their annual salary, measured in millions and divided into 5 different categories, in 3 particular years.
Overall, there was an upward trend in most of the number of US households in 2007, 2011 and 2015. Besides, 100,000 dollars or more by far registered the highest figures whereas 75,000 to 99,000 dollars invariably stayed the lowest volume.
Upon giving the bar chart close scrutiny, 25 millions of households earned less than 25,000 dollars in 2007. This figure observed a slight increase to around 29 millions in the next 4 years, followed by a marginal decline to 27 millions in 2015. Similarly, the 25,000 to 49,999 dollars grew from 27 millions to almost 30 millions in 4 yearly intervals before dropping to approximately 28 millions in 2015.
The number of households within 50,000 to 74,999 dollars and 75,000 to 99,999 dollars income ranges remained relatively stable across all 3 years, staying around 20 millions and 15 millions respectively. Lastly, the household with an annual salary exceeding 100,000 dollars went down from 30 millions in 2007 to around 28 millions in 2011, but experienced a significant rise to 34 millions in the 4 following years.
