^a Due to the small percent of respondents in the categories "some of the time", "most of the time" and "all of the time", the percents for these categories are pooled together in the Table. For ease of reading, the percent of respondents reporting "a little of the time" is not shown in the Table; it corresponds to 100 minus the percents shown in the categories "none of the time" and "some of the time or more" for each item.
^b Confidence interval at the 0.95 level.
