I'm not surprised to read that urban creep (I'm assuming this would include suburban sprawl as well, with construction of new homes and subdivisions) would outpace all other land-use categories.
What is interesting to note is just how much land is owned by the 100 largest private landowners (the article doesn't state whether these private landowners are individuals or corporations). According to the article, ownership of land by these private landowners have grown since 2008 from 28 million acres to 40 million, a growth rate of 42.9% within a decade if my arithmetic is right.
What I would like to see is a graph indicating the overall trends in private landownership over the past 50 years or so. I'm curious how readily available that information is, since I wonder whether ownership of land is a matter of public record in the US.
