Want to compare Old Town to Crystal City? I can tell you there are huge differences in the lifestyles, the types of homes and the commutes in these two neighboring villages. But I can't really quantify that information. Fortunately, I don't have to. Our site has a great tool for researching and comparing neighborhoods, with information about schools, education, incomes, age of homes and more.
In the meantime, over the next few days I expect to run a few reports and publish them to give you an idea of what you can learn about neighborhoods of Northern Virginia. By the way, what's nice about this system is that you can use it to compare any neighborhoods in North America. See how Lansing stacks up to Fairfax, or how Falls Church does vs. Peoria. The research engine is here.

This statistic actually doesn't give Old Town Alexandria its full historical range. Many homes in Old Town are older than 80 years of age. But Old Town has a suprising number of new homes as well. Crystal City is definitely younger.

Crystal City and Old Town are both leaders in household income, though perhaps Old Town is a bit more affluent. (Perhaps this is why there are more owners in Old Town?)
