Write a report for a university lecturer describing the information in the graph below. 

The graph compares the men and women smoking in Someland between the years 1960 to 2000. It can be clearly seen that the rate of smoking for men and women both is currently declining and the the fewer women have smoked throughout the period.

In 1960, 600 men in every 1000 was smoking. The number decreased gradually to 500 by 1975 and continued to fall but more steeply to 250 in 2000. In contrast, the rate of women smoking in 1960 was very low at only 100  in every 1,000. However, the number was increasing shparply and reach its high as 300 in every 1000 by 1975. Afterwards, the number started declining gradually and had dropped to 200 in 2000. 
[ By 1968 this increased to 170, and increased again but more steeply to 320 in 1977. The rate of female smokers then remained stable at 320 until 1984 at which point the figures began to decline and had dropped to 200 by 2000. ]

In conclusion we can see that the rate of smoking in men dropped throughout the whole period but was always at a higher level than the female figures. The rate of smoking in women increased until 1977 but then dropped for the rest of period.
