Each of these is absent for a reason, not by oversight. The Area Score is calculated without them; the weighting is on the methodology page.

Reported crime

Offenses reported to police are published by department rather than by town, so AreaProfile shows a rate only on city profiles, and only where that city’s department submitted every month of a year. Either no municipal department reports for this place — many smaller communities are policed by the county — or its department did not report every month of the year. Either way there is no figure to show. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.

Taxes

Income and sales taxes are not published: no source covers them nationally with a method open enough to check. Property taxes are shown in the housing section but are not part of the score. The cost-of-living index above is a price level for all consumption, not a household budget, and it excludes taxes. Nothing here is individualized tax advice.

Anything about a specific address

Every figure describes an area, not a street or a house.

Every city here is measured on the same scale from the same source releases, so the comparison is like for like. A higher Area Score reflects AreaProfile’s standardized weighting rather than a judgment about which is the better place to live.
