Note 1: Questions asked were: How do you think people risk harming themselves physically and in other ways when they do each of the following activities? Response choices were for each of 11 activities: (1) no risk, (2) slight risk, (3) moderate risk, and (4) great risk. The unweighted n's for each age group are smaller than those shown in Table 1.1 because of differing patterns of nonresponse to the risk questions across age groups.
Note 2: Due to improved procedures, these estimates are not comparable with previous year estimates and should not be used for trends with pre-1994 data.

aDifference between 1996 estimate and 1997 estimate is statistically significant at the .05 level.
