I am a grade 12 student currently working on my independent study on the changing roles of men and women in the workplace, family and in society. Could you please send me some information or statistics?

For statistics (and information) about the changing role women and men play in all those areas, you should reference a book called The American Women. This is chock full of substantive information. They update the book every year, so you should look for the latest year. They do comparative studies over the years---tracing different issues.
