So I have this project...

I know I know.. This is the wrong type of forum to post this in.. but I needed help fast.
Theres a question in my assignment sheet asking me:
What reasons can you give for the differences in the distribution of male and female employees in the various type of industries?
All I need help is with secondary industries.(where people make semi-finished products into finished products) I already have some reasons but I don't think it is enough.
I tried to research on the web but couldn't find that much.
Could someone help me with a few reasons. No troll please

Thank you

I checked the Faq and I didn't see this Against the rules. So I think it should Be okay

EDIT: I forgot to tell you this.

Primary industries contain the least amount of workers.

secondary industries contain the second most amount of workers.

and tertiary industries contain the most amount of workers.

there are more male workers then female workers in the secondary and primary industries. but less male workers then female workers in tertiary industries
