Band 6+: IELTS Academic Writing Task 1: You should spend about 20 minutes on this task. The chart below shows the number of households in the US by their annual income in 2007, 2011 and 2015. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The bar chart depicts the number of households in the United States, categorized according to their annual income, across the years 2007,2011, and 2015.

Overall, households earning between $50,000 and $99,999 maintained relatively stable levels with minor fluctuations, whereas other income groups demonstrated an upward trajectory.

Obviously, households with an income exceeding 100,000 were the most numerous throughout the period, starting at roughly 30 million in 2007. Despite a slight dip to 27 million by 2011, its numbers rebounded steadily, peaking at 34 by 2015. Similarly, the two lowest income brackets—below 25,000 and between 25,000 and 49,999—saw steady increases to approximately 28 million and 30 million respectively, although both experienced slight decreases by 2015.

However, the remaining brands exhibited contrasting trends. Notably, households earning between 50,000 and 74,999 was the only group that did not record any growth, remaining basically unchanged, hovering around 22 million over the period. Meanwhile, those in the 75,000 to 99,999 bracket, though starting from a very low base of less than 15 million, witnessed a modest increase, reaching approximately 15 million by 2015.
