The chart illustrates the number of households in the United States categorized by annual income in 2007, 2011, and 2015. The data is measured accurately in millions and compares five income brackets.
Overall, the number of households earning less than $25,000 decreased, while those in higher income brackets saw an increase over the period. The most significant growth occurred in households earning $100,000 or more, whereas the lower-income group showed a downward trend.
In 2007, households earning less than $25,000 accounted for around 27 million, while those in the highest income bracket ($100,000 or more) were approximately 25 million. Over the next four years, the number of low-income households slightly declined to around 26 million, while the wealthiest group grew to roughly 28 million.
By 2015, this trend had continued, with the lowest income group dropping further to about 23 million. Conversely, households earning over $100,000 saw a sharp rise, surpassing 30 million. Other income brackets remained relatively stable, with only minor fluctuations.
These trends suggest an overall increase in household wealth in the United States over time, with a notable shift towards higher-income groups.
