Where the Grandparents Cohabitate...

According to the census data I extracted from the neighborhood reports on the City Planning site, in 1999 there were 6,038 households in Pittsburgh in which a grandparent was living with one or more grandchildren under age 18.

In 2,727 of the households (45%), the grandparent was the primary caregiver for the grandchild.

Below are the top 20 neighborhoods in terms of absolute number raising grandchildren. Obviously many of the grandparents are under age 65 (many are probably in their forties), but I included the % of households with someone over 65 in the neighborhood anyway:
