IELTS Task 1 Bar Graph Band 9 Sample Report (1)
The bar chart delineates the distribution of households in the United States according to various annual income brackets in the years 2007, 2011, and 2015. These figures are represented in millions and cover five distinct income categories, ranging from under $25,000 to $100,000 or more.
A salient feature of the data is the incremental growth in the number of households earning $100,000 or more, starting from a modest 30 million in 2007 to reaching approximately 34 million by 2015. This category is in stark contrast to the household income bracket of $75,000 to $99,999, which experienced the least variability and hovered around 14 million across the observed years.
Interestingly, the households with incomes between $50,000 and $74,999 demonstrated remarkable stability, consistently maintaining a count close to 21 million throughout the years in question. Conversely, the lowest income brackets—those earning less than $25,000 and those within the $25,000 to $49,999 range—saw initial peaks in 2011, with counts reaching 28 and 30 million respectively, but subsequently declined to levels slightly below their 2007 figures by 2015.
Conversely, the mid-range income category of $25,000 to $49,999 deserves particular mention as it underwent a notable oscillation. After an initial uptick in 2011, it reversed its trajectory and settled at around 28 million households in 2015.

IELTS Task 1 Bar Graph Band 9 Sample Report (2)
The bar graph elucidates the households in the US by their annual income strata for the years 2007, 2011, and 2015. Expressed in millions, the data encompasses five disparate income echelons, extending from sub-$25,000 to $100,000 and beyond.
A conspicuous trend that manifests in the data is the ascendant trajectory of households in the highest income echelon—those amassing $100,000 or more annually. This specific category embarked on a gradual but undeniable ascent, commencing at a modest 30 million households in 2007 and culminating at an approximate 34 million by 2015. This upward mobility serves as a striking juxtaposition to the $75,000-$99,999 income bracket, which remained notably static, oscillating around the 14-million mark throughout the given temporal frame.
Equally compelling is the unflappable consistency exhibited by households situated in the $50,000-$74,999 income tier. Their numbers steadfastly hovered around the 21-million threshold across the scrutinized time period. In a diametrically opposite vein, the income strata at the lower end of the spectrum—specifically, households earning under $25,000 and those within the $25,000-$49,999 bracket—witnessed transient zeniths in 2011, surging to 28 and 30 million, respectively. However, these figures subsequently regressed, aligning more closely with their 2007 baseline by the year 2015.
Furthermore, the income category spanning $25,000-$49,999 merits heightened attention due to its pronounced volatility. After achieving a transient apogee in 2011, this bracket underwent a retracement, ultimately stabilizing at approximately 28 million households by 2015.
