How to scrape specific info from Instagram and Facebook

I want to scrape different demographic information of the people that follow certain FB and Instagram accounts. I'm interested in age, gender, marital status, location, work and level of education (ideally).

Please let me know if you know a way, a tool or a service to do that.

Thank you.

The thing you are lookng for is a lot personal and so people who don't publically write it won't be possible to see using a tool.
