Realtors can't answer this question due to Fair Housing Laws but you can find your answer at the US Census Bureau. Here is the link:
You can also reference the New York Times. The Real Estate section has articles titled "Living In" that might be of interest to you. Here are some regarding Stamford and Norwalk:

Keller Williams Realty Group
As a RealtorÂ® based in Stamford and covering much of Fairfield County, while representing home buyer clients exclusively, I have been fortunate to have helped many select between Stamford and Norwalk. About four out of five who have selected one of these towns have picked Norwalk. Since each is a city, with all that a city has in terms of areas and neighborhoods, a good introduction to each would seem in order so you may compare the two with knowledgable guidance.
You can start your comparison online at http://www.Rich.Listingbook.com, where you can set up your own personal home search site, as my guest, with your search criteria for each community. Then, each morning, you will receive an email with all the new listings that meet that criteria, and you can mark your favorites. I will get an email as well, showing me what you are exploring, and I can send you messages about some of those favorites. There is no cost or obligation, and it is entirely FREE.
If, later, you wish my help in any way, I remain at your service. Since I only work for buyers who become my clients, I do not list properties or represent any sellers or their agents, ever! So, I have nothing specific to promote and therefore no conflicts of interest. You'll get to see everything you need to see to find the very best home for you . . . without the traditional pressure!
As a single female, I understand your concerns.
Both cities are great for singles each with large corporate presence and vibrant night life. But most importantly, safety first! As with any city, certain areas are more desirable than others. I definitely agree with Anna, intra-city demographics will assist you to hone in on areas that you would like to focus your search. Also important is the feeling you get when you travel through different areas, as you indicated.
I have a friend who moved from Bronx NY and lived in both Norwalk and Stamford. I am happy to put you in touch with her to provide you with insight on moving from NY to CT.
Finally, I am an active agent within Stamford and Norwalk and happy to take you on a tour and show you places, provided you are not currently working with an agent.
Good luck with your search.
