I want to know the answer to the following question:
Which parts of the city of Detroit are densely populated?
All the background I'm provided with is that "There were 49,982 housing units at an average density of 1,748.0 per square mile (675.0/km²), making it less densely populated than inner-ring Detroit suburbs like Oak Park and Ferndale (and than Detroit proper), but more densely populated than outer-ring suburbs like Livonia or Troy.". Is that enough to answer the question?
