The graphs below illustrates the change of ratio between female and male workers from 1957 to 1995. (Am not to sure since I cannot see the graph) In 1975, the ratio of females and males (women and men) who worked in the communications industry was nearly same. In 1995, 2,500,000 men and 6,000,000 women worked in communications industry . For 20 years the number of women working in communication industry has been growing. But in 1975 and 1975, proportion of working in Manufacturing is same. (Not sure how to fix the last sentence, please check!)
