Anchorage is the largest city in Alaska, located in the Southcentral region. Anchorage is a port city with a population of over 300,000. The published population density is very low as the city covers over a whopping 1900 square miles, compared with Chicago's 225 square miles or New York City's 300 square miles. But most of the land in Anchorage's city limits is uninhabited and mountainous. Anchorage is a municipality: essentially a combined city and county. The urbanized portion of the city is a relatively compact area defined by Muldoon Road to the east, Rabbit Creek Road to the south, and Cook Inlet to the north and west. Several small suburbs are within the Municipality of Anchorage, while physically outside what most Anchorageites would call the "Anchorage" proper area. These include Eagle River and Chugiak to the north and Girdwood to the south.
