Survey error is the extent to which findings from the survey sample differ from those of the population of interest. The large nationally representative surveys discussed here are designed to minimize error. Nevertheless, it is impossible to eliminate all of the multiple potential sources of error. Investigators must identify and consider how potential survey error can bias the results of their analyses. Statistical strategies can minimize the impact of these potential sources of error on study findings.
The EPA recently conducted a survey in which San Bernardino, and its county, has the worst air pollution rating of any city\county in the U.S. I'm sorry, I don't have the numbers, though.
