Identity is how a person defines and sees themselves and can be a result of several different factors including gender identity, social identity, geographical identity, political identity, loss or lack of identity, and how those around see them.
How important different factors are to identity is up to the individual as well as how and where they were raised.
I am planning on using this project to explore my cultural identity and heritage. I am from a multicultural family with my dad being from the UK and my mum being South African, but her family is originally from India. My racial identity is important to me and I do not often get a chance to properly explore it.
