Sample Answer
Introduction
The bar chart illustrates the sales of three types of home security systems—wireless, wired, and smart—from 2000 to 2023. The sales figures are measured in units.
Overview
Overall, sales of wireless and smart home security systems exhibited a significant upward trend, whereas sales of wired systems declined consistently over the period.
Body Paragraph 1: Wireless and Wired Systems
In 2000, wired systems dominated the market with 150,000 units sold, while wireless systems lagged behind at 50,000 units. However, sales of wireless systems rose steadily, reaching 300,000 units by 2023, thereby surpassing wired systems by a substantial margin. In contrast, the sales of wired systems decreased gradually, falling from 150,000 units in 2000 to 60,000 units in 2023.
Body Paragraph 2: Smart Systems
Smart systems, which were not sold in 2000, started gaining traction around 2005. By that year, only 5,000 units were sold. However, sales surged significantly over the years, reaching 200,000 units in 2023. The growing interest in smart technology likely drove the rapid increase in sales.

Key Considerations When Writing
Vocabulary
- Dominated (verb, /ˈdɒmɪneɪt/)
- Consistently (adverb, /kənˈsɪstəntli/)
- Substantial (adjective, /səbˈstænʃəl/)
- Gradually (adverb, /ˈɡrædʒuəli/)
- Traction (noun, /ˈtrækʃən/)
Grammar and Structure
- Use of the past simple tense to describe completed actions in the past (e.g., “Sales of wired systems decreased gradually.”)
- Comparative structures to show changes over time (e.g., “Sales of wireless systems rose steadily, reaching 300,000 units by 2023”).
- Phrases for summarizing trends (e.g., “overall”, “in contrast”, “likely drove”).
Conclusion
To excel in IELTS Writing Task 1, especially on topics like sales trends of home security systems, it is crucial to interpret the data accurately, use relevant vocabulary and grammar, and structure the response smartly. Focus on the main trends and key details, and practice consistently with real-life data for the best results. Achieving a Band 7+ requires clarity, coherence, and grammatical precision.
