# The CDC strongly urges all data users to follow the general rule of not reporting or interpreting percentages
based upon a denominator with fewer than 50 unweighted respondents or confidence intervals with a half-width
of > 10.
N = Cell Size, NH = Non-Hispanic, % = Percentage, C.I.(95%) = Confidence Interval (at 95 percent probability
level).
Percentages are weighted to population characteristics.
Unless stated differently above, Missing, 'Don't know', and Refused responses are excluded.
