Westport Commercial Real Estate | Gold Coast Shopping Destination.  The coastal town of Westport is approximately 20 square miles, with a population of over 27,000. The town has remarkably high average household income of $255,000+, more than three times the U.S. average and more than double the average for the state of Connecticut.  A destination shopping area, Westport CT draws customers from a distance, as well as its residents. Like Greenwich, Westport offers a mix of upscale local, regional and national retailers that are rarely found together in a Main Street type environment, attracting shoppers from up and down Connecticut’s gold coast.  Within a 15-minute drive time of the central business district, the population jumps to over 150,000 with an average income exceeding $170,000, resulting in total buying power for in-store retail goods (excluding food and drink) of $4 billion+.
