Sample Answer 1:

The bar chart compares the number of households in the United States within five annual income categories—less than $25,000, $25,000–$49,999, $50,000–$74,999, $75,000–$99,999, and $100,000 or more—in the years 2007, 2011, and 2015.

Overall, households earning $100,000 or more increased steadily over the period, while those earning less than $25,000 saw a decline. Middle-income households (earning between $25,000 and $99,999) fluctuated, with mixed trends across the categories.

In 2007, the number of households earning less than $25,000 was the highest, exceeding 30 million. However, this figure decreased consistently to around 27 million in 2011 and 25 million in 2015. In contrast, households earning $100,000 or more rose from approximately 22 million in 2007 to 28 million in 2015, marking the most significant growth among all income groups.

The remaining categories experienced varying patterns. Households earning $25,000–$49,999 saw a slight decline, dropping from about 28 million in 2007 to 25 million in 2015. Those earning $50,000–$74,999 peaked at 25 million in 2011 before falling slightly to 23 million in 2015. Meanwhile, the $75,000–$99,999 group remained relatively stable at approximately 15 million throughout the years.

These trends suggest a shift towards higher-income households over the observed period, indicating potential economic growth.
