The provided line chart illustrates the number of males and females smoking in a university in Someland, with a survey of 1000 people, from 1960 to 2000.
Overall, it is evident that the figure for males experienced a downward trend, while the opposite was true for females. Such a contrasting pattern narrowed the gap between the two genders, with the figures ending at relatively similar numbers.
In 1960, the number of males smoking commenced at 600 people, which was more than five times as high as that of females (under 100). By 1975, the former had recorded a steady decline, falling to 500 people. By contrast, the latter increased moderately by 100 in 1965, after which it remained quite stable at this level until 1970, prior to surging to a peak of more than 300 people in 1975. From that point onwards, the disparity between the two categories narrowed considerably , with a difference of roughly 200 people.
By the end of the period, both followed the same pattern, with men smokers declining more pronouncedly. Specifically, the number of male smokers halved to approximately 250 people at the end, whereas that of females stabilized until 1980, before dipping gradually to 200 people over the same period
