    A sample survey is preferable than a census because it takes less time to do a sample survey. It is less expensive to do a sample survey than a census of a whole population and if the survey procedures are done right it can be a good representation of the population.

    Sample survey can target specific groups without biased results. Also requires less training and support

    Thanks all for your contributions. Discussion is not a place where you are expected to chime in. Please make sure that if you add a comment it is something new. Also try to take the topic deeper. Finally be sure that what you write contributes to the discussion. How a survey is conducted (“Good representation of the population”) is a different issue than whether a survey or census should be done.
    One point that is worth emphasizing is that a census of a large population takes a long time. By the time the census is complete and the analysis is performed, issues and opinions could have changed or may not be of interest any more. Political opinions especially and often social opinions like support of gay marriage often change too quickly for a census to be the tool of choice.
