This really isn't a good measure since roads will be denser in urban areas and less dense in rural areas, thus leading to exactly the same issues as directly using population density.

But beside that, the public road mileage for Texas is off by a factor of two. This DOT document lists 303,176 miles of public road in Texas. http://www.fhwa.dot.gov/policy/ohim/hs04/htm/hm10.htm

Please be so good as explaining you point better, I do not understand it. If you are going to wire up every lot in the state, you will have to traverse all roads in the state to do a cable drop to every lot in order to do so. What does road density have to do with it?

When building wireline communication networks, the deciding factor costwise, is the number of linear cable sheet miles. As such miles of road is a good proxy for comparing deployment costs between locations.

Please note that I am discussing wireline broadband. If you have you heart set on wireless coverage, then we have to talk different measures, and even there population density is not the tell all metric.

My bad. However that does not still make it cheaper to build in Finland, it merely brings up Texas and Finland to par on miles of road per population. Several things still favour Texas in the cost per capita, such as: economics of scale, ability to perform construction year around and no need to put utilities under the frostline.

There are no technical or cost reasons for Texas to be unable to offer the same level of broadband service as Finland. It all comes down to other reasons, perhaps such as lack of political will in Texas.

A number of different factors at play.

Imagine a layout where cables do not have to follow roads.

Imagine a layout where one cable can serve buildings on two roads. Certainly much, much easier when the buildings are dense.

Imagine a thousand people living in one building in the center of a thousand square miles, served by one cable. Imagine a thousand people living one per square mile in a thousand square miles. The population densities are the same. The cabling costs are not.

Imagination will take you very far, and in this case, very far from the matter at hand. Texas and Finland are real places, not figments of imagination.

Not very likely in the real world. Easements and rights of way are not available or not readily available among arbitrary paths. In any case, even if you were to cut through peoples back yards, you would still most of the time just be following a parallellish path to the roads.

These are real places we are talking about. Have a look at a map.
