City Cities have a remarkable ability to
self-organize as they grow. Neighborhoods of like-minded people and similar
kinds of businesses establish themselves organically, from the bottom up. Thus,
New York gained Chinatown and Little Italy, the Garment District and the Flower
District, enclaves that appeared regardless of such top-down forces as
planning commissions and zoning laws. Such communities-within-the-community
emerge on their own, lending cities their distinctive personalities.
