! Interpret data with caution.
‡ Reporting standards not met.
1 American Indian includes Alaska Native, Black includes African American, Pacific Islander includes Native Hawaiian, and Hispanic includes Latino. Respondents who identified themselves as being of Hispanic origin are classified as Hispanic, regardless of their race.
2 The response categories for race/ethnicity changed in 1999 making comparisons of some categories with earlier years problematic. In 1993, 1995, and 1997, Asian students and Pacific Islander students were not categorized separately and students were not given the option of choosing more than one race.
NOTE: "On school property" was not defined for survey respondents. The term "anywhere" is not used in the YRBS questionnaire; students are simply asked how many times during the past 30 days they used marijuana. Population sizes from the Digest of Education Statistics, 2005 and 2002 (NCES 2006-030 and NCES 2003-060) for students in grades 9–12 are 13,093,000 students in 1993; 13,697,000 in 1995; 14,272,000 in 1997; 14,623,000 in 1999; 15,061,000 in 2001; 15,723,000 in 2003; and 16,286,000 (projected) in 2005.
