This is not necessarily true. The number of populated places also increases.
There are many, many more desirable places to live now in the US than there were 50, or 100 years ago. While desirability is subjective, I'd argue that the growth in the number of desirable places to live is outpacing population growth. The revitalization of many American downtowns, as well as the necessary reorganization of our land use, will further propel this trend.
