The graph below shows the rate of smoking per 1000 people in Someland from 1960 to 2000.

The line graph compares the ratio of smokers among 1000 females and males in Some land over a four-decade period starting from 1960.

Overall, there was a major decrease in the rates of men using cigarettes while an upward trend was observed for the proportion of female smokers.

In 1960, approximately three-fifths of men smoked, six times higher than cigarettes usage in women. In the next five years, the percentage of smoking for former decreased to 580 people, continuing to fall steadily a further by 100 to 500 around 1975. While the rate of female smoking had a great increase of 100 people before remaining unchanged until 1970, followed by surging at its highest point at over 300 per 1000 people.

From 1980 onwards, both the percentage of female and male smokers shared a relatively similar trend. Both figures declined gradually, dropping to 200 people, almost to the same in 2000, which shows that the percentage of female ratio doubled in 40 years.

Overall, there was a major decrease in the rates of men using cigarettes (We do not "use" cigarettes. We smoke them.) while an upward trend was observed for the proportion (wrong usage) of female smokers.

In 1960, approximately three-fifths of men smoked, six times higher than cigarettes usage in women.

Sample essay:


The line graph compares the rates of smoking for men versus women in Someland from 1960 to 2000.

The smoking rate is defined as the number of people who smoke out of 1000 people in their population sector. In this 40-year period, the rate for men was always higher than for women, and the largest difference was at the beginning. By the end of the period, the gap had narrowed significantly as the men's rate dropped and the women's went up.

In detail. the time period can be divided into two intervals, 1960-1975 and 1975-2000. In the first interval, the two curves were strongly negatively correlated as the rate for women tripled from 80 to about 310 whereas for men, it dropped from 600 to 500. The gap had narrowed from 520 to 190, over 60%. In the second interval, the two curves were positively correlated in that both decreased linearly. However, the gap between them continuously became smaller and smaller. The women's rate had a very broad peak from 1975 to 1990, averaging about 300. The rates ended at about 230 for men and 200 for women.

The smoking rate for women.


A ratio is expressed by two numbers - a:b.

For example:

The ratio of teachers to students in private schools (1:8) is better than in public schools. (1:25). Private school students get much more personal attention.

The number of men teaching engineering in universities is higher than women. A ratio of 9:1 is common.

The ratio between the number of males and females in a society is referred to as the gender ratio. At birth, more males than females are born; the ratio is 105:100.

So a proportion of a ratio or percentage of a ratio makes no sense, mathematically.

Thank you so much. I get it.
