2015 census tract population density

The US Census recently released 2015 census tract population density data, including census tract population density. I figured midway through the decade would be a good point to update where these stand because they give greater insight in smaller-scale population changes. I looked at all the census tracts in Franklin County and came up with the following map series.

First, the population in 2015.

Next, the population density of tracts in 2010, as reference.

And now 2015.

On the surface, it’s difficult to see the changes, but put side by side, you can tell there have been a lot of increases across the county. To make this more visible, I made the following maps.

You can see that some of the strongest density increases occurred around Downtown and the Short North, New Albany, parts of the Campus area, and Dublin.

The map above gives a straightforward look at where the density increased and decreased. As you can see, the increases FAR outweighed the decreases. Most of the latter were scattered except across the Far South Side and parts of the Whitehall area.

Here were the top 20 most dense census tracts in 2015.
1. 1810: 29,508.2 South Campus/Victorian Village
2. 1121: 25,287.9 Main Campus
3. 13: 21,961.4 Campus/Indianola Terrace
4. 1110: 18168.6 North Campus/Tuttle Park
5. 10: 17386.3 Campus/SoHud
6. 12: 16,981.9 Campus/Iuka Ravine
7. 20: 13,030.5 Short North/Victorian Village
8. 17: 12,872.3 Weinland Park
9. 6: 12,153.6 Old North Columbus
10. 21: 10,853.5 Short North/High Street
11. 8163: 10,255.3 Lincoln Village/Southwest Columbus
12: 4810: 9,557.4 South Central Hilltop
13. 47: 9,492.7 North Central Hilltop
14. 6352: 9,434.0 Northwest Columbus/Henderson Road
15. 57: 9,257.4 Brewery District/South German Village
16. 5: 9,177.9 Old North Columbus
17. 6933: 9,090.9 Forest Park East
18. 16: 8,980.5 Weinland Park
19. 4620: 8,928.6 North Central Hilltop
20. 1820: 8743.3 Victorian Village

It’s obvious that the High Street corridor is the most dense of the city, racking up most of the top 20.

Now here are the 20 tracts with the largest density increases 2010-2015.
1. 1121: 4,375.9
2. 6: 2,178.5
3. 21: 1,934.9

20. 9333: -194.9 Linwood

So there you have it. The Census Tract Maps page gives demographic and population data for census tracts going back to 1930.



2016 Election Results

I’m not going to get into any debate on the candidates themselves or what I personally thought/think of them. That’s not the point of this post, and frankly, there’s already plenty of opinions all over the internet on this. This post is about the 2016 election results for Ohio.

First, here is a map of total Democratic votes within Ohio’s counties.

As is typical, Democratic votes were most concentrated in counties with large cities.

Here are the metro areas that provided the most Democratic votes.
1. Cleveland: 561,368
2. Columbus: 450,146
3. Cincinnati: 339,159
4. Akron: 166,653
5. Dayton: 164,079
6. Toledo: 152,505
7. Youngstown: 100,395

And the top 10 counties with the most Democratic votes.
1. Cuyahoga: 398,271
2. Franklin: 351,198
3. Hamilton: 215,719
4. Summit: 134,256
5. Montgomery: 122,016
6. Lucas: 110,833
7. Stark: 68,146
8. Lorain: 66,949
9. Butler: 58,642
10. Mahoning: 57,381

Here is how Democratic votes changed by county between 2012 and 2016.

As you can see, only a handful of counties saw Democratic votes increase in 2016 over 2012, Franklin County being one of them. Some of the biggest losses were in traditionally blue areas like Northeast Ohio.

And the map for total Republican votes.

Republican votes by metro area.
1. Cincinnati: 440,375
2. Columbus: 429,930
3. Cleveland: 400,321
4. Dayton: 210,807
5. Akron: 151,997
6. Toledo: 134,558
7. Youngstown: 102,640

Top 10 counties for Republican votes.
1. Franklin: 199,331
2. Cuyahoga: 184,211
3. Hamilton: 173,665
4. Montgomery: 123,909
5. Summit: 112,026
6. Butler: 106,976
7. Stark: 98,388
8. Warren: 77,643
9. Lucas: 75,698
10. Clermont: 67,518

And here is the change of Republican votes in 2016 vs. 2012.

Most of Ohio’s counties saw increased Republican turnout, though again, Franklin County bucked the trend and actually saw declines.

Finally, a map of the net % change for each county and whether it trended more Republican or more Democratic vs. the net of the 2012 election.

Almost all counties saw a net decrease of Democratic votes/increase in Republican votes. Only 3 counties of 88- Franklin, Delaware and Hamilton- trended more Democratic in 2016 over 2012. All the other 85 trended Republican.
