MSA's are county based and are standard across the country, However in New England there is an alternate, NECTA which is based off towns. Some cities have relatively similar MSA's and NECTAs and some do not.
Here is a truncated list (2010)
City MSA POP NECTA POP
Boston 4,552,000 4,703,000
Providence 1,601,000 1,301,000
Hartford 1,212,000 1,121,000
Bridgeport 916,000 926,000
Worcester 916,000 577,000
New Haven 856,000 597,000
Springfield 631,000 683,000
Portland, ME 529,000 357,000
Manchester 407,000 187,000

Now some cities, like Boston, Hartford, and Bridgeport are in the same ballpark. Providence, Springfield have some difference. Worcester, Manchester, Portland and New Haven have huge population shifts.

This is due to Counties being very inexact. While the entirety of Worcester County is in the Worcester City MSA, about 150,000 are in the Leominster/Fitchburg NECTA, as well as loses a couple border towns to Providence and Boston. Even the metros that stay the same have border changes, Hartford loses parts of Northern Hartford County, but extend past its western MSA border. In Providence's case it loses SErn Bristol County to a Metro that only exists on the NECTA level, New Bedford. Boston's largest gain comes from the Nashua area which is assigned to Manchester on the MSA system but Boston on the NECTA system.

Now obviously the US doesn't have towns in total geographic coverage like New England does, but I would be curious to see a ZIP code level Metro and how cities change, as that would be about equal to the NECTA.

However, maybe this only matters in parts of the country where metros run into each other and can steal each others suburbs.

Do NECTA's use the same criteria, but just use towns/zip codes instead?

Yes, NECTA is identical to MSA but on a Town by Town vs County by County Level.

would seem the NECTA approach would be better as doesn't force whole counties one way or another


I would imagine that Philly would pick some border areas in MSA border counties if this type of approach we used nationwide


to me makes more sense as counties can be to large or onerous and lose resonance

In Virginia, there are very few incorporated cities. So this approach wouldn't work there (and most of the South).

Everybody has a ZIP code, I wonder if that would be a more accurate way of determining metro populations.

However, its probably not worth the effort, unlike municipal and state populations, Metro populations don't matter in the distribution of state or federal tax dollars.

MSA doesn't work at all for NC. The Triange and Triad are arbitrarily separated into two half metros, while very auxiliary counties are included.

Note that there is more traffic between Wake and Durham counties than any other two counties in the state.

The town system makes more sense to me. There are large rural areas and unconnected areas in counties that are included in MSAs. There are also counties that split between two metros that would be rounded one way or another.

I'm surprised that SF and San Jose aren't already the same MSA. So many residents of SJ already make the long drive or train ride daily to SF for work anyway.

By contrast, LA and OC are in the same MSA. Many who live in north OC commute to Long Beach or even DTLA for work, but many in Long Beach or elsewhere in south LA County commute to OC cities like Irvine and Santa Ana for work.

there are Urban Areas but they are only updated every 10 years rather than every year like MSAs.

Urban areas though have the similar county aspects of MSA they don't allow for the splitting of counties to different MSAs but likely better than MSA in many ways
