Some maps showing housing density in units per square KM, by census block group.  Pretty fine grained look at it...

 

First the state

 

 

 

Then Southwest Ohio

 

 

 

Interesting to see that low density of housing units between Dayton and Columbus, east of Dayton and Springfield....larger farms so fewer houses?

 

Also maybe a better visual of exurban sprawl than "urbanized area", as this shows higher density for areas that might not be urbanized....ribbon developement on country roads and smaller hobby farms???

 

 

 

 

 

 

 

 

 

  Excellent map. Thanks for posting.

 

  It would be interesting to compare with previous years.

 

  It should also be noted that the measurement is housing units, not population. Abandoned houses count. Buildings other than houses don't count at all. So, highway-related sprawl, with fast food, gas stations, and so on, does not show up as well as in other images.   

That is really cool!  Where did you find it?

 

It would be interesting to see a different classification with the highest class being smaller.  As it is, some places with regular suburban density are showing up dark red just like the densest urban areas.

 

I see it was made by people here at UW-Madison, but whoever they are, they're not in Geography.  Bah!

Im not sure..i was just sufring around google images....and found it.

 

I thought it was odd they where using square km not square miles.  Using that measure you would get a higher density reading, no?

 

 

 

The Ravenna Armory (or whatever it's called) shows up very well.

I've found the web pages for Hammer (in Rural Sociology) and Radeloff (in some forest thing).  They and others have some paper on housing density in the Midwest (which I don't feel like reading right now), but scanning through that and looking at the maps shows it includes everything BUT Ohio! :x  So what did they do with this Ohio map, and why did they make it?  Intriguing...

 

Well, here's that paper in any case (PDF): http://www.drs.wisc.edu/hammer/research/documents/Hammer_LUP_2004.pdf

What amazes me are the turns of I-75 north of Dayton (the Piqua's, the Sidney's) in which development is linear ALMOST all the way to Lima.  And of course, of note, the Ohio River cities.

 

Is it possible to find northern Kentucky and Southeast Indiana for the Cincinnati-housing extension?

for the highest denisty shown,128 units/Km2 is about eqivalent to 2 units per acre

(1 Km2 = 247 Acres)

Uber-cool map!

 

Interesting to see that low density of housing units between Dayton and Columbus

 

Maybe it has something to do with the moratorium on new construction in the Darby Creek watershed? You can see development stradling the entire expanse next to the watershed in far western Franklin Co.

What amazes me are the turns of I-75 north of Dayton (the Piqua's, the Sidney's) in which development is linear ALMOST all the way to Lima. 

That was the first thing I noticed.  You can follow really well to Sidney, then it dies off a little in northern Shelby and Auglaize counties and picks back up again around Lima and on northward to Toledo (although not nearly as distinctly as the southern portion).

Highways are the devil.....whiping societies growth around their evil empire. :whip: :whip: :whip:

While highway development is evident in parts of this map, I think that's not really what's going on in the I-75 corridor north of Dayton.  The development there is really following the Miami River, not the highway.  In other words, it's the same pattern that's awlays been there.  The gap after Sidney is where the river turns toward the east a bit, and between there and Lima there is no linear pattern to speak of (which, if there were one, would be attributable to the highway).  Now, obviously the highway has contributed to the growth of these places, but the only area along there that seems to exhibit clearly linear highway-related development is between Vandalia and Troy, including Tipp City.

.the link to a website that has this and other maps....also hypertext to Indiana and Kentucky graphics,  as requested by ColDayMan...(plus other states):

 

Ohio Wildland-Urban Interface Maps, Stats, GIS

 

What i posted isnt the best resolution...check out this one for more detail and one will see its more fine grained....the developement that looks contiguous on the maps upthread is'nt really when you zoom in:

 

Ohio

 

I'm really impressed with the granularity on these maps...

 

 

I was at that site but somehow missed that page where this map is.  Thanks for that link!
