Socioeconomic variables: Chi square or Fisher exact

Hi there,

I am working on socioeconomic variables with SAS.
I have set of variables like age, community, marital status, education level etc. I want to do basic descriptive and see if there are significant differences between 2 communities.
I am unsure of which test to use, Chi square or Fisher exact? My sample size is 250.
Can I use simple ANOVA to see if there are differences between 2 communities? Any insights please?

Thanks very much!
