add_health — Adolescent health (ADD HEALTH) (1994)

Description

Directed friendship networks among students in 84 communities in the United States, from the in-school questionnaire of the National Longitudinal Study of Adolescent Health (Add Health), administered in 1994–95 to 90,118 students in grades 7 to 12. Each community consists of one high school, and in some cases also of a "sister" school (typically a feeder junior high school); each community is a separate network (comm1 to comm84). The networks were prepared by J. Moody.

Each student was given a paper-and-pencil questionnaire and a roster of all students in the school (and in the sister school, if any), and was asked to list up to five closest male friends and up to five closest female friends, in order of closeness. For each nominated friend, the student indicated in which of five activities they had participated together: visiting the friend's house in the last seven days; meeting after school to hang out in the last seven days; spending time together last weekend; talking about a problem in the last seven days; and talking on the telephone in the last seven days. A directed edge $i \to j$ means that student $i$ nominated student $j$ as a friend. Since nominations across schools were allowed, the networks are given at the community level.

The networks have the following properties:

(Node) sex (1: male, 2: female, 0: unreported).
(Node) race (1: white, 2: black, 3: hispanic, 4: asian, 5: mixed/other, 0: unreported).
(Node) grade: the school grade (7 to 12, 0: unreported).
(Node) school: the school (0 or 1) within the community, only for communities with two schools. Node attributes are missing for community 48.
(Edge) activities: the tie value, equal to one plus the number of the five activities the student reported doing with the friend (from 1, a nomination with no reported activities, to 6, all five activities).
