People often get hung up on OKC's low population density, which is merely a mathematical result of the large rural areas that have been annexed over the years. It tells us nothing about the density of the built environment or the actual "sprawl". The US Census Bureau has just come out with its revised "Urbanized Area" numbers, based on the 2010 Census. These numbers give us the relevant density. Below are OKC's urban population and density along with a number of other cities that are either somewhat similar in size to OKC or are often discussed on this board, arranged in order from highest to lowest density:
