I want to survey a nationally representative sample of the American population.
This group of survey respondents reflects the U.S. census.
(The respondents will be ages 18+ and split evenly on gender.)
I want to survey a specific group of people based on one or more attributes.
Choose your survey respondents by who they are, what they do, where they live, etc.
(E.g., female grocery shoppers over 40 or dog owners in NYC.)
