From the San Fran Examiner:

Despite efforts to stem the tide of family flight, the population of children in San Francisco continues to ebb.

Families that remain in The City are bucking the trend that has plagued San Francisco for years as the number of children — defined as people up to 17 years old — has dropped from 181,532 in 1960 to 107,524 today, according to the latest U.S. Census Bureau figures. The 2000 census counted 112,802 youths.
