It includes water if it has been annexed. Also, for Raleigh it includes Durham County. But for Cary and Wake Forest it does not include the Chatham and Franklin County portions. Had to spend a few minutes looking at the data source.

Thanks. I wonder why they werenāt consistent in their approach that includes Raleighās total area, but not other municipalities?

Well in the city limit layer in Imaps (and the source data) Raleigh city limits are included probably because they wanted the data to be included. Cary and Wake Forest either donāt care or at least have not asked to have all limits included.

@TedF Do you know what the total area of Raleigh was in 2010? The Census site gives land area, but I am not sure if thatās the same number. I just want to understand how much area was annexed into the city over the last 10 years.
I donāt know it but I believe anybody could figure it out through Imaps. They started keeping track of the dates annexations occurred in the City Limit layer and with a little time could probably summarize and acquire the information. But the census says it was 143.77 square miles in 2010.

148.40 - 143.77 = 4.63 m2
So, Raleighās only added 4.63 m2 while it added over 70,000 through 2019. Thatās pretty good in my book.

Maybe this will help. The two lightest greys are Raleigh city limits and current ETJ (ExtraTerritorial Jurisdiction). The darker shade of grey is the SRUSA (Short Range Urban Statistical Area). The darkest shade of grey is the LRUSA (Long Range Urban Statistical Area). This will all be in Raleigh city limits eventually (through annexation).

Wow! So, Raleigh is going to completely block expansion from either Garner or Knightdale into the area that will grow from the completion of 540. Very, very interesting.
While this might presume years, if not decades to happen, I suspect that it will be quicker when 540 is completed through the area.

From Wikipedia
Durham Area: 111.82 (Land) Pop. Est. 2019: 279,993 Density: 2,503/ sq mi
Cary Area: 58.86 (Land) Population estimate 2019: 170,282: Density: 2,893/sq mi
Cary/Apex/Holly Springs/Garner: Area 113.54 Population estimate 2019: 298,801 Density: 2,632/ sq mi.

Most of the expansion land is zoned rural residential, and it will do nothing to push Raleighās density metric higher, or even add to the population in any significant way. I suspect that most of it wonāt be annexed in my lifetime! Frankly, itās fine with me if it never is annexed.

Thanks for doing that homework. Itās very interesting to see that a collection of comparable land area Wake burbs are more densely populated than the Triangleās second largest city. I have known for a while that Cary was more densely populated, but Iāve never considered it as a collection of towns.

Well zoned rural residential is actually a good thing. It will be easier for developers to amass parcels because little will be built on it already. The zoning will change once Raleigh makes it part of their ETJ. And I suspect land around 540 will probably be higher density. It looks like this final part of 540 will not begin construction until 2029. So completion may be around 12 years. So there will probably be nothing much happening at least till then.

Thereās a lot of wetland in that area, so I suspect that protecting that is going to be paramount in how itās developed. It could either be larger parcels with horse farms, etc., or larger parcel estate homes. It remains to be seen if folks who want to spend that sort of money want to be in that location. Again, Iām not terribly concerned about it ever being annexed.

I assume the 0 population Umstead State Park is included within the city limits(?). If so, what would Raleighās density be subtracting the State Park from the total square miles of the city?
If itās in the city limits, itās part of the metric.
The park is 5599 acres, and thereās 640 acres in a square mile. Thatās 8.75 square miles.
If the city is 148.40 square miles today, and if we subtract 8.75 from it, weāre left with 139.65 square miles. If that were the case, and we go by the latest Census estimate that we have from 2019 (474,069), the city would have a density of 3,395 ppl/m2. Alas, thatās not the case, so itās a moot point.

Page 37250 of the 2010 OMB regs regarding merging MSAs:
Two adjacent CBSAs will merge to form one CBSA if the central county or counties (as a group) of one CBSA qualify as outlying to the central county or counties (as a group) of the other CBSAā¦
A county qualifies as an outlying county of a CBSA if it meets the following commuting requirements:
(a) At least 25 percent of the workers living in the county work in the central county or counties of the CBSA; or
(b) At least 25 percent of the employment in the county is accounted for by workers who reside in the central county or counties of the CBSA.
A county may be included in only one CBSA. If a county qualifies as a central county of one CBSA and as outlying in another, it falls within the CBSA in which it is a central county.
For Durham vis-a-vis Wake, it seems like criterion A is just missed, while criterion B is met.
Elsewhere in the document is evidence of a 2010 letter-writing campaign by Triad partisans! āThirteen commenters expressed concern about the current delineations of the Greensboro-High Point, Winston-Salem, and Burlingtonā¦ā Little do they know that, even though Alamance currently sends more commuters to Guilford, Orange is just a few percentage points behind.
Anyhow, Iām going to tweet at @ncdemography to see if they want to clear this up, since apparently both Triangle and Triad really care about this.
BTW, Wikipedia really does have the most complete dataset of old Census counts, apparently because a grad student didnāt have enough data entry work to do:

Doesnāt Raleigh-Cary Durham-Chapel Hill meet that requirement I donāt understand!!!
From my understanding (which is nil), Wake is the core county due to size, and since the highest percentage of commuting goes away from the core county, Durham canāt be tied to Wake. However Wake is too big to be a satellite to Durham. So we reached an impasse. If they looked at the totality of commuting, it would show Wake-Durham is tied more than any other counties in the state.
