New York, NY
What they have in common is that Cudahy's population density, at 21,684 per square mile, is not dissimilar to New York's 26,402 per square mile. I can't be positive, but I am pretty sure no building in Cudahy is more than three floors tall. New York is the 5th densest municipality in the US, while Cudahy's is 10th. If one visits Cudahy, one won't feel particularly crowded either. But there is no wasted space.
