The following report analyzes the bar graph illustrating the distribution of US households according to their annual income in the years 2007, 2011, and 2015.
Overall, the chart displays changes in household income brackets over the three mentioned years, categorizing households into five income groups. There is a noticeable increase in households earning over $100,000, while households with incomes below $25,000 experienced a slight decrease from 2011 to 2015.
The data reveals a significant rise in the number of households earning more than $100,000, surpassing 30 million in 2015. Conversely, households with incomes between $45,000 and $99,999 remained relatively stable over the period. Although there was an uptick in the number of households earning less than $25,000 in 2011, this figure slightly declined by 2015. The proportion of households earning between $50,000 and $74,999 also exhibited consistency throughout the years.
The substantial increase in households earning $100,000 or more, accompanied by a decrease in those earning less than $25,000, indicates a positive economic growth trajectory. This pattern suggests a shift towards higher-income brackets among US households during the years under consideration.
