While it’s still highly debatable just how much the population of the city of Detroit lost in the decade from 2000 to 2010, it’s clear that there was a net loss. But the real picture is told by this map from the Detroit News: some areas lost, some areas gained.
The vast east side of Detroit, already having worse problems compared to the west side of Detroit, experienced the deepest population losses. But areas surrounding Hamtramck saw large gains, a sign of positive influence from that enclave. There are other notable bright (green) spots and basically stable (yellow) blocks.
