I want to know the correct preposition to use in 
 this sentence, which I wrote for my writing class assignment. 
I have already received my grade, so I'm not trying to cheat or something.

> 
> '...Freedom can also refer to being secure **in home** and hometown'
> 
> 
> 

Is it correct to use 'in home'? or is it wrong? I know there are alternatives which fit better (e.g: at) but what about 'in'?

I looked this up on the internet but opinions seem to vary significantly.
