It’s Foolish To Define Austin By Its City Limits


Cities grow in two key ways, and when we talk about how “big” a “city” has become, or how fast it has grown, we often conflate two forms of expansion: spatial and demographic. On the one hand, the footprint of a city changes shape; year to year and decade to decade, growing municipalities annex more and more land. On the other hand, urban growth also involves a bigger and bigger batch of humanity living in and around that bulging municipality.

But the one hand does not always know what the other is doing, and when population growth outpaces geographic growth — like it has in Austin — things get messy.
