Mapping out good and Bad Areas in Columbus.

[Rebeca Trabachini]

Hi everyone, I am trying to map out good & bad areas in Columbus CA. Ideally avoiding high crime areas and and highlighting neighborhoods grade B C and D.
What I got so far is
Good areas: Hilliard, grove city, Worthington, Westville, New Albany and downtown in general (Grand view, olde town east. Bexley and German Village).
Bad areas: Hilltop.

Does anyone know more zip codes or areas I should avoid?
Or other areas good to invest other than downtown?

Any feedback is appreciated. Thank you!
