Some years before I was born, my parents lived in Michigan City, Indiana. But this was only briefly–before too long, they ended up in Valparaiso, the town I grew up in. Since 1970, Michigan City’s population has fallen by a quarter, while Valparaiso’s has increased by a third. Today Valparaiso has more people than Michigan City does, and nearby Chesterton’s population has doubled its 1970 level. Another nearby town, LaPorte, has stagnated:
Why do Valparaiso and Chesterton grow while Michigan City and LaPorte decline or stagnate? I’ve been thinking about it, and I have a theory.
