And that’s how we arrived at the bizarro-world reality that Lincoln Park actually lost roughly the same number of housing units as Englewood between 2000 and 2012.
You can see how dramatic the effect is by looking at population growth around the borders of downtown: where relatively loose downtown zoning holds sway, the number of residents boomed. But instead of gradually tapering off as you get further away, there are sharp drop-offs all around the central area. Often, a few blocks where the population grew by 50% or more are right next to a few blocks where population actually declined. In most cases, zoning plays a crucial role in those disparities.
But so what? Why does any of this matter?
For one, it matters because if the number of housing units in a neighborhood is capped, as that neighborhood becomes more desirable, affluent new arrivals will outbid existing residents and people of moderate income, pushing up housing prices and creating newly segregated enclaves. If we want regular people to be able to live in some of our safest, most transit-accessible neighborhoods, allowing the supply of housing to grow with demand is a crucial part of that affordability.
