Birth family means the family you are blood related to.
People use the term birth family because even though they are blood related they weren't a proper family to them because they might not have grown up with them or they might have not been a proper family to them.

Many people who are adopted like to use birth family instead of real family because they were never a real family to them if they didn't looked after them properly. Thats why people also use birth mum and birth dad extra extra.
because family isn't about blood family is about who you love.
I don't live with my birth family.
