A population survey, better known as a census, entails the collection of each unit in the population. In sample survey information is collected from a subset of the population. The subset, or sample, needs to be selected carefully so that it is representative of the whole population and, if that requirement is met, statistics based on the sample are good estimators for the corresponding population parameters.
A sample survey is asked of a limited group of people, while a census is conducted in an attempted to get an answer from all people in a geographical area.
It's not.
difference between survey and experiment
survey is one of the techniques to conduct a research while research is the process of getting a targeted information or facts about some thing by using sample
The population is every data point you intend to generalise the survey results to. The sample frame is those data points that you can pick from for the survey. The sample is which of these data points you actually survey, and the sample size is how many of those data points there are. For instance, if you have 700 students in a school, and you have access to 300 of them, and decide to give 30 of them a survey, the sample size is 30.
A Census is the type of survey for a complete population. A Sample Survey is only a portion of the population which is used to make predictions on the representation of the actual population.
A census is a statistical enumeration and analysis of a certain population, be it humans, animals or plants - groups that grow and change over time. A survey can be a tally of opinions or answers. See "Family Feud" when Richard Dawson says, "Survey says...!!!!"
The population mean is the mean calculated over every member of the set of subjects being studied. It is usually not available and a survey is used to find an estimate for the population mean. The mean value of the variable in question, calculated from only the subjects included in the sample (or survey) is the sample mean. Provided some basic statistical requirements are met, the sample mean is a "good" estimate of the population mean.

Statistics: Survey of an entire population, as opposed to a sample survey.
Random selection.
A sample survey is a method that obtains data from a subset of a population to estimate some attributes of that population. An experiment is a controlled study in which the researcher trys to understand cause-and-effect relationships.

Researchers define a "population" which consists of elements with defined characteristics. Example: All the matriculating students at Providence College. If the researcher studies the entire population as defined above, it is called a "census". If, on the other hand, the researcher takes a subset of the population, a sample, and studies it it will be a sample survey (or study in more general terms.)
