The survey of 600 Orange County adults was conducted Jan. 31-Feb. 2 during evening hours, using a random sample of listed and unlisted telephone numbers. An equal number of men and women were interviewed. Respondents were guaranteed anonymity, although some agreed to be re-interviewed by a reporter.
The margin of error due to chance variations in the sample is plus or minus 4% at the 95% confidence level. That means it is 95% certain that the results are within 4% of what they would be if every adult Orange County resident were interviewed.
The poll was conducted for The Times by Mark Baldassare and Associates, an Irvine-based public opinion research firm, with fieldwork by Discovery Research Group.
