Agree. However that pattern is true in basically every city, which is why cities skew young. There are a large number of powerful factors driving families with kids to suburbs: lower crime, better public schools, larger houses for the money, more land for the money, more convenience for driving and shopping, and lower overall taxes are some of the biggest ones. Cities have to succeed in spite of that, and usually that’s because of appeal to young people, social activities, general appeal of sights/activities/restaurants, and convenience to work. I do think for all its faults that Baltimore is still much more appealing than Columbia for many people 5-10 years out of college. And while DC is even more appealing, that’s where price differences come into the equation.
