aWTCHR eligibility groups are not mutually exclusive; approximately 26% of registrants belong to more than one eligibility group.
bTotals do not add up to 71,437 because not all the enrollees answered all the questions. N missing = 2 for gender, 358 for age, 2,568 for smoking status, 528 for dust, 339 to 881 for witnessing events, 205 to 493 for types of injuries. Totals and percentages are based on non-missing responses only.
cHousehold income is displayed only for enrollees 18+ years of age at interview. N 18+ = 68,444 for total, 30,546 for rescue–recovery workers and volunteers, 559 for school staff, 440 for adult students, 12,371 for residents, and 41,666 for building occupants, passersby, and people in transit. N missing=7,994 for household income.
dIncludes enrollees from other states (N = 5350), Canada (N = 76), Puerto Rico (N = 33), and those with no zipcode reported (1,292).
N/A Data not available because the majority of student enrollees were under the age of 18 at the time of interview, and proxy interviews resulted in missing data.
