The bar chart below gives information about vehicle ownership in China.

Write a report for a university lecturer describing the information.

My essay:

The bar chart reveals the changes in the number of cars owned by people in China between 1987 and 1999. The data is given in the number of vehicles per ten thousand people. Overall, vehicle ownership significantly increased over the period, with relatively slow growth at the beginning and at a faster pace in the last several years.

As the data suggests, in 1987 for every 10,000 Chinese, there were only 250 cars in use. This number doubled in the next couple of years and grew by 300 in 1991. The following years, however, showed only marginal rise to around 900 automobiles.

Starting from 1995, the car ownership rate was on a rapid increase, as it doubled in 1995 and kept this tendency till the end of the period. Extra 2000 vehicles were bought in the years between 1995 and 1999 and slightly more than that in 1999. This resulted in every four out of ten Chinese citizens owning a car in that year, or 4100 per 10,000 people.

You did not read my advice, did you?


And where did you find this essay? The bar chart is incorrect. There is a grammatical error in the legend, and the information is completely ridiculous.


If you try to write essays on invalid topics, you will not benefit. You will only be confused.


The bar chart reveals (Not a good word choice for a professor!) the changes (No, that is not quite correct. What does the time series bar chart actually plot?) in the number of cars owned (That is not correct. It does not plot the number of cars owned. Vehicles includes motorbikes, trucks and cars. A car is only one type of vehicle.) by people in China between 1987 and 1999. The data is given in the number of vehicles per ten thousand people. Overall, vehicle ownership significantly increased over the period, with relatively slow growth at the beginning and at a faster pace in the last several years.

This time series bar chart plots the growth of vehicle ownership in China during the twelve-year period between 1987 and 1999. Specifically, it gives the number of vehicles per thousand people in the odd-numbered years.

Do not put any comments about the data content in the first paragraph. Make a new paragraph.

You need to learn some more sophisticated math vocabulary. This is an exponential curve. The data is increasing exponentially over time. Does this curve have the same shape as the bar chart?


Overall, the growth rate fits an exponential curve, except there is a noticeable flattening between 1991 and 1993. There was an increase in this value by a factor of 16 over the span of twelve years.

As the data suggests, (There is not guess or suggestion. Treat this as actual measured data.) in 1987 for every 10,000 Chinese, there were only 250 cars in use. This number doubled in the next couple of years (two years) and grew by 300 in 1991. The following years, however, showed only a marginal rise to around 900 automobiles.

Starting from 1995, the car ownership rate was on a rapid increase, as it doubled in 1995 and kept this tendency till the end of the period. Extra 2000 vehicles were bought in the years between 1995 and 1999 and slightly more than that in 1999. This resulted in every four out of ten Chinese citizens owning a car in that year, or 4100 per 10,000 people. (That is not the legend on the chart. )

Thank you for such a helpful and deep feedback.

I have learned a lot from your examples of how to properly do this task.
