Why is sampling method preferred to census method?

It is more suitable if the population is heterogeneous in nature. It is more suitable if the population is homogeneous in nature. The results are quite reliable and accurate under the census method.

Which is better a census or a survey?

Such a survey usually requires a very large sample size and often a census offers the best solution. Data for small areas may be available, assumimg satisfactory response rates are achieved. Data for sub-populations may be available, assumimg satisfactory response rates are achieved.
