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.
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.
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
its better because we often don't have to survey a large population, so a sample is quicker, easier, requires few ressources, little time and can be more accurate if a person is not there to answer it because a sample could represent that person.
A survey is used more often than a census because a census requires everybody to respond, while a survey only needs a few people. This means a survey is advantageous for many reasons:It doesn't matter if not everyone responds, you can just survey more people.It is much cheaper to survey than hold a census.It is less effort to hold a survey than hold a census.It takes less time to hold a survey than hold a census.
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...!!!!"

Statistics: Survey of an entire population, as opposed to a sample survey.
In a census observations are recorded for each member of the population. In a survey only some of them are.
becuase it is more accurate.
A sample survey may be preferable than a census because it can be more comprehensive. While its research only involves a subset, it is typically more accurate.
A sample survey is quicker and cheaper. If the survey is well designed then the results are likely to be close to their true values.
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.)
A sample is a portion and a census measures absolutely everyone in the whole country. A representative sample measures a small number of people who fit a particular category of people: surveying 200 white male smokers between 20 and 40 who have had surgery for throat cancer (out of a total number of say 35,000 men who fit that profile).
