When comprehensive information is required. It may also be the better option if the characteristic of interest is important but very rare. In such a case, a sample may give an underestimate.

When is census necessary instead of sampling?
census is conducted for group data so if it is a sampling data is taken it would lead to lot of non sampling errors
Why is a sample usually preferred over a census?
Less time and less cost for a sample.
What are the differences between census and sampling?
A census would get data from 100% of the population (or at least close to 100%). Sampling would be to get data from some of the population (much less than 100%).
Why is a census preferred to a sample?
Sampling can be more accurate than a census as there is greater control of interviewers and less chances of mistakes being made as the data is collated
Is questionnaire probability sampling technique?
A questionnaire has little to do with sampling technique. Sampling technique is to do with who gets the questionnaire and that can be any sampling technique: the questionnaire can be sent to everyone (census), to a random sample, stratified random samples, to random samples in clusters, by quota or convenience. Or a pile of questionnaires can be left for respondents to pick up - self-selection.

Advantages of census over sample survey?
It is more accurate, unbiased and includes every item in the population, whereas sampling may be biased, and sampling is not totally representative.

What is the main difference between sampling and census?
The main difference between sampling and census is that in sampling, a subset of the population is selected and studied to make inferences about the entire population, while in a census, data is collected from every individual or element in the population. Sampling is more cost-effective and less time-consuming compared to a census, which requires resources to collect information from every unit in the population.

What are the advantages of cluster sampling?
basically it is cheaper than other methods so it is preferred over other methods.
Advantages of census over Sampling in Statistics?
There are several advantages of sampling over census (i.e. selection of wholepopulation for analysis).Firstly, the costs on sampling should be much lower than that on census. For example,for the government by-census (note: population census is usually conducted onceevery ten years and a by-census is conducted in the middle of the intercensal period),one fifth of the population is large enough to declare what the government wants toknow. There is no need to spend several times of dollars to interview the entirepopulation in the society.Secondly, a quality guru (Deming, 1960) argued that the quality of a study was oftenbetter with sampling than with a census. He suggested that, "Sampling possesses thepossibility of better interviewing(testing), more thorough investigation of missing,wrong , or suspicious information, better supervision, and better processing than ispossible with complete coverage". Research findings substantiate this opinion. Morethan 90% of survey error in one study was from non-sampling error1, and 10% or lesswas from sampling error2. (Donald et al., 1995)Thirdly, sampling can save the time. The speed of execution reduces the time betweenthe recognition of a need for information and the availability of that information.1 Non-sampling error is the error of research due to factors other than the sample size and samplingmethod, including non-response, bad communication with interviewees, measurement error, etc.2 Sampling error is the error during research due to the sample size and sampling method.
