The chart illustrates the distribution of household incomes in the US for the years 2007, 2011, and 2015. Overall, there is a gradual increase in the proportion of households with higher annual incomes over this period.
In 2007, the number of households earning less than $25,000 stood at approximately 25 million, which saw a slight increase to nearly 30 million by 2015. Similarly, households earning between $25,000 and $49,000 also experienced a gradual rise from around 25 million in 2007 to just over 30 million by 2015.
Conversely, households with higher incomes demonstrated more significant growth. Those earning between $50,000 and $74,999 remained relatively stable at around 20 million throughout the period. The same trend is observed for households with incomes between $75,000 and $99,999, hovering just under 15 million for all three years.
Notably, households earning $100,000 or more exhibited marked growth, increasing from just under 30 million in 2007 to approximately 35 million in 2015. Particularly striking is the surge in households earning $200,000 and above, which saw a significant rise in numbers by 2015.
In summary, while lower income brackets experienced modest increases, the higher income categories, especially those earning $100,000 or more annually, demonstrated substantial growth over the period from 2007 to 2015.
