How to Read the Tables

The following pages present the detailed tabulations of survey results. The data are percentaged vertically and, therefore, should be read from top-to-bottom. The total number of interviews, both weighted and unweighted, appears at the top of each column. Percentages are calculated on the weighted bases. Percentages may not add to 100% due to weighting factors or multiple responses. Where an asterisk (*) appears, it signifies any value of less than one-half percent.
