One thing noticeable about Norwalk, although not a huge city, is that it has a large population of people who are young, single, educated, and upwardly-mobile career starters. That’s because Norwalk is full of single people in their 20s and 30s and who have undergraduate or graduate degrees and are starting careers in professional occupations. This makes Norwalk a pretty good place for young, educated career starters looking to find many people like themselves, with good opportunities for friendships, socializing, romance, and fun.

One of the nice things about Norwalk is that it is nautical, which means that parts of it are somewhat historic and touch the ocean or tidal bodies of water, such as inlets and bays.
