Population Growth Patterns in Metro Areas, 2000-16

[JerryArkansas]

Orlando would be nice to see.

Metro Phoenix:



I'll put Orlando on the to do list.  It probably will go together with Tampa, as the granularity for both metros is very low, and Florida is narrow.  I can get most of both metro areas and coasts in with a 1:1,000,000 scale.

NOLA would be verry interesting.

[cinyc]

Central Florida (Basically, the I-4 corridor from Tampa to Orlando to Daytona Beach, though part of Voluisa County got cut off in order to add the city of Sarasota):



The usually grey or blue cities near the middle of the map in Southern Orange County is Lake Buena Vista and Bay Lake, a.k.a. Disney World.  Very few people actually live in those cities, which is why the population gain usually doesn't reflect the rest of the map.

It really isn't.  There's very little granularity there, because there are very few incorporated cities.  But I'll put it on the list.

do we have Metro Portland yet?

[cinyc]

do we have Metro Portland yet?

No. 

Of the top 25 metros, we're missing Minneapolis, San Diego, Denver, St. Louis, Baltimore (sort of, though much of it is on the DC and Philly Maps and there's extremely little granularity there, anyway), Charlotte, San Antonio and Portland.  I'm going to try to do those over the next few days, after Southeastern Louisiana.  Minneapolis will require a bit more work to update my 2010-16 County Sub shapefile to include Minnesota, which will add granularity.

They do, but the Census Bureau discards forms from Micky Mouse and Donald Duck who claim that they live in the Magic Kingdom.

New Orleans and Southeast Louisiana (inlcudes Baton Rouge and the Mississippi Coast):



You can really see what counties/parishes were hard hit by Hurricane Katrina in 2005.  They rebounded over time.

[Linus Van Pelt]

Is it me, or does there seem to be more variation in the 2000-10 data than the 2011-16 data for the outer areas of SE Michigan and SE Wisconsin?  Does Census revise the population estimates after the census to reflect the next Census or something?  Or is Census just estimating things by county in the smaller jurisdictions until the 2020 census?

The annual population estimates for states and counties are based on births, deaths, and migration figures. The census bureau doesn't have these data for cities and towns, but they do make an annual estimate of housing units for municipalities based on building permit data. The annual population estimates for municipalities take the county estimate and then distribute it among the municipalities based on housing units. But if I understand the method correctly, they don't take into account changing rates of occupants per housing unit - so if one town has a new subdivision marketed towards young families with around 4 people per new house and another town has one marketed towards seniors with 1-2 people per house, this won't show up in the annual estimates.

After the census, the annual estimates for the cities and towns are revised for the previous decade based on the actual census data.

Denver:



Colorado Springs is on the map, too, since Park County is part of the Denver Metropolitan Area, and south Park County is parallel to it.  Boulder is its own metro, but is also on the map.  It's part of the Denver CSA, though, as is Weld County, which is partially on the map.

Sorry.  Southern Park County.  I shouldn't have capitalized the South.

[cinyc]

San Diego:



It's a one-county metro area, at least on the U.S. side of the border.

[cinyc]

Portland, Oregon Metro:

[cinyc]

Greater San Antonio:

[Bismarck]

How about Indianapolis/central Indiana?

[cinyc]

Charlotte Metro:

[cinyc]

Indianapolis:

[cinyc]

I put a list of the top 53 metros with links to the maps done so far in the first post.  Those are the metros with a population greater than 1,000,000.  I plan on trying to map all 53, eventually.  I've already done 23 of the top 25 and a handful of others.

South Park High School is in Fairplay, the larger dot in the west central part of the county. There are residential subdivisions just west of the Jefferson County line off of US-285. Commuting into Denver or just across the line to work in a grocery store pulls the county into the Denver MSA.

Minneapolis-St. Paul Metro:



Edited to correct map.

[cinyc]

Greater St. Louis:



That's the last of the top 25 metros.

Minneapolis-St. Paul Metro:

It looks like only Hennepin is changing in the 11-12, 12-13, and 13-14 panels.

[cinyc]

It looks like only Hennepin is changing in the 11-12, 12-13, and 13-14 panels.

That's a bit bizarre.  It's possible I forgot to change the county sub layer, but I think Ramsey is on the place layer, too, so you'd think that would change along with Hennepin if that were the issue.  I'll check into it tonight.
