The bar chart provides data on the US household income distribution in three years, 2007, 2011 and 2015. Overall, there was an increase in the number of families in the brackets of under $25,000, $25,000-$49,000, and $100,000 or more dollars, while the figures for the mid-level income groups stayed relatively unchanged throughout the period.

In 2007, 25 million households in the US had a total income of less than $25,000, while 5 million more families earned at least $100,000. Afterward, in 2011, the US saw the figure for the former rising to around 29 million, outsripping the latter’s figure by 1 million. Four years later, the trend was reversed, as the least wealthy group shrank slightly to around 27 million families and the most affluent bracket grew to 34 million. Meanwhile, the number of households with their income in the $25,000-$49,999 range started at approximately 26 million and went up by around 3 million, before dropping to about 28 million in 2015.

In the rest of the groups, there was hardly any difference between 2007 and 2015 regarding the $50,000-$74,000 category as the number of families remained around 21 million. Similarly, families whose total income was around $75,000 to $99,999 were numbered at roughly 14 to 15 million throughout the period.

"the brackets of under $25,000, $25,000-$49,000, and $100,000 or more dollars" -> "the income brackets of less than $25,000, $25,000-$49,000, and $100,000 or more"
Explanation: The term "income brackets" provides clarity and specificity, while "less than" is more formal than "under." Additionally, "dollars" is unnecessary since the context of income already implies currency.
"the figures for the mid-level income groups stayed relatively unchanged" -> "the figures for the middle-income groups remained relatively stable"
Explanation: "Middle-income" is a more precise term than "mid-level," and "remained" is a stronger verb choice than "stayed." "Stable" conveys a clearer sense of consistency than "unchanged."
"the former rising to around 29 million" -> "the former increasing to approximately 29 million"
Explanation: "Increasing" is a more formal and precise term than "rising," and "approximately" is a more academic alternative to "around."
"outsripping the latter’s figure by 1 million" -> "surpassing the latter’s figure by 1 million"
Explanation: "Surpassing" is a more formal and precise term than "outsripping," which is less commonly used and may confuse readers.
"the trend was reversed" -> "the trend reversed"
Explanation: The passive construction "was reversed" is less direct than the active form "reversed," which enhances clarity and conciseness.
"the least wealthy group shrank slightly" -> "the lowest-income group decreased marginally"
Explanation: "Lowest-income" is more precise than "least wealthy," and "decreased marginally" is a more formal expression than "shrank slightly."
"the most affluent bracket grew" -> "the highest-income bracket expanded"
Explanation: "Highest-income" is more specific and formal than "most affluent," and "expanded" is a more precise term than "grew."
"the number of households with their income in the $25,000-$49,999 range" -> "the number of households with incomes in the $25,000-$49,999 range"
Explanation: "Incomes" is a more precise term than "income" in this context, as it refers to the income of multiple households.
"started at approximately 26 million and went up by around 3 million" -> "began at approximately 26 million and increased by approximately 3 million"
Explanation: "Began" is a more formal alternative to "started," and "increased" is a more precise term than "went up." Using "approximately" instead of "around" maintains a formal tone.
"there was hardly any difference" -> "there was minimal difference"
Explanation: "Minimal" is a more formal and precise term than "hardly any," which is more colloquial.
"were numbered at roughly 14 to 15 million" -> "were estimated at approximately 14 to 15 million"
Explanation: "Estimated" adds a level of precision and formality that "were numbered at" lacks, and "approximately" is more formal than "roughly."

Band điểm Task Achivement ước lượng: 7

Band Score: 7

Explanation: The essay provides a clear overview of the main trends in the data, highlighting the key features of the chart. The essay also makes comparisons where relevant, but could be more fully extended. For example, the essay could have provided more specific details about the changes in the number of households in each income bracket.

How to improve: The essay could be improved by providing more specific details about the changes in the number of households in each income bracket. For example, the essay could state that the number of households with an income of less than $25,000 increased by 4 million between 2007 and 2011. The essay could also provide more analysis of the data, such as explaining the possible reasons for the changes in the number of households in each income bracket.

Band điểm Coherence & Cohesion ước lượng: 7

Band Score: 7.0

Explanation: The essay logically organizes information and ideas, demonstrating clear progression throughout the response. It effectively presents a central topic within each paragraph, with each section focusing on specific income brackets and their changes over the years. The use of cohesive devices is appropriate, although there are moments where the connection between ideas could be smoother, indicating some under- or over-use. Overall, the paragraphing is clear, but there could be slight improvements in the logical flow of ideas.

How to improve: To achieve a higher band score, the essay could enhance cohesion by using a wider range of cohesive devices and ensuring that transitions between ideas are more fluid. Additionally, refining the paragraph structure to ensure that each paragraph not only presents a topic but also connects more clearly to the overall argument would strengthen coherence.

Band điểm Lexical Resource ước lượng: 7

Band Score: 7.0

Explanation: The essay demonstrates a sufficient range of vocabulary that allows for flexibility and precision in conveying the data from the chart. The use of phrases like "income distribution," "mid-level income groups," and "most affluent bracket" indicates an awareness of less common lexical items. However, there are occasional inaccuracies in word choice, such as "outsripping," which should be "outstripping," and some minor errors in spelling that detract from the overall fluency. The vocabulary used is generally appropriate for the task, but there is room for improvement in terms of sophistication and control.

How to improve: To enhance the lexical resource score, the writer should focus on using a wider range of sophisticated vocabulary and ensuring accuracy in spelling and word formation. Incorporating more varied sentence structures and avoiding repetition of common phrases would also contribute to a higher score. Additionally, practicing the use of uncommon lexical items in context can help to convey precise meanings more effectively.

Band điểm Grammatical Range & Accuracy ước lượng: 7

Band Score: 7.0

Explanation: The essay demonstrates a variety of complex structures and produces frequent error-free sentences. The writer shows good control of grammar and punctuation, with only a few minor errors, such as "outsripping" instead of "outstripping." The overall clarity of the communication is maintained, and the essay effectively summarizes and compares the data presented in the chart. However, there are some grammatical inaccuracies and awkward phrasing that prevent it from reaching a higher band score.

How to improve: To achieve a higher band score, the writer should focus on minimizing grammatical errors and enhancing sentence variety. This can be done by proofreading for typos and awkward constructions, as well as incorporating more complex sentence forms with accurate punctuation. Additionally, ensuring that all terms are used correctly and consistently will help improve overall grammatical accuracy.
