1 Estimates of "Frequency of gang-related fights, attacks, or other violence at school" and "Gangs involved in the sale of drugs at school" were derived from the full sample of students.
2 "All other races, not Hispanic or Latino" includes Asians, Pacific Islanders, and American Indians (including Alaska Natives) and respondents of two or more races. For this report, not Hispanic or Latino students who identified themselves as being of two or more races (1 percent of all respondents) were included in the "all other races, not Hispanic or Latino" category. Respondents who identified themselves as being of Hispanic or Latino origin were classified as "Hispanic or Latino," regardless of their race.
3 Urbanicity refers to the Metropolitan Statistical Area (MSA) status of the respondent's household as defined in 1990 by the U.S. Census Bureau.
4 Rates for students who responded that their schools did not give grades or there was no alphabetical equivalent are not reported.
5 Victimization data are taken from the Incident Report of the National Crime Victimization Survey and appended to the School Crime Supplement (SCS) data file. Readers should note the reference period for the victimization data is "the last 6 months" while the reference period for the SCS is "the last school year."
NOTE: "Violent" victimization includes serious violent crimes (rape, sexual assault, robbery, and aggravated assault) and simple assault. "Theft" includes attempted and completed purse snatching, completed pickpocketing, and all attempted and completed thefts, excluding motor vehicle theft. Theft does not include robbery, in which the threat or use of force is involved. "At school" includes the school building, on school property, on a school bus, and going to and from school. Details may not sum to 100 percent because respondent-volunteered "don't know" responses are included in the base for the percentages listed. Population size for students ages 12–18 was 25,967,000 in 2007.
