Almost 30 percent of Pima County's kids live in poverty, but the problem is spread unevenly across the metropolitan area.

When the percentage of kids in poverty is mapped by census tract, the corridor from North Oracle Road through downtown to South Nogales Highway especially sticks out.

In the tracts along Oracle from downtown to Miracle Mile, between two-thirds and three-quarters of children live in poverty - less than $17,916 a year for a family of three. The size of the census tract does not necessarily represent the size of the population living within it. Although the tracts average about 4,000 inhabitants, their partitions also take into account physical features such as streets and political boundaries such as American Indian reservation districts.
