In a previous post, we examined the population densities in Wayne, Oakland, and Macomb counties. This post examines the population densities for the outlying counties in Southeast Michigan: Livingston, Monroe, St. Clair and Washtenaw.

As can be seen in the map below, the population densities in four outlying counties are much lower than those in Wayne, Macomb and Oakland counties.

The data used for these maps came from the Southeast Michigan Council of Governments (SEMCOG) December 2012 population estimates, which are the most recent available.  To calculate the population density, each municipality’s  population was divided by  its square mileage.

There are no municipalities in the outlying counties in Southeast with a population density categorized in the highest bracket (4,700 to 10,770 residents per square mile) and only three municipalities  in the second highest bracket (3,152 to 4,699 residents per square mile): Port Huron in St. Clair County and Ann Arbor and Ypsilanti in Washtenaw County. Ypsilanti has the highest population density of all the communities presented in this post with 4,296 residents per square mile. In contrast, neither Livingston nor Monroe have any municipalities  with a population density above 3,151 residents per square mile(the maximum density for the middle bracket).
