I removed the section richest best educated zip code I didn t understand what it meant how can Waban be the richest best educated zip code without being the richest Also how do we define best educated I looked at the census data for 02468 and there are lots of statistics that might mean best educated largest fraction with bachelor s degrees smallest fraction of high school dropouts etc I d be glad to see this section come back if someone could sharpen it to some verifiable fact and provide a reference It would be very interesting if it were true that for instance Waban has a higher fraction of people with graduate degrees than any other zip code The census bureau page for Waban is at
