The advantages of the sampling method of collection of data over the census method:
1. Sampling requires less time and labor than census because only a part of the population has to be examined. The sampling results also can be analyzed much faster
2. Sampling usually results in a reduction in cost in terms of money and manpower. The total cost of the sample survey is expected to be much smaller than a complete census.
3. There is generally a greater scope in a sample survey than in census. Some inquiries may require highly trained personnel or specialized equipment for a collection of data, then the census may be inconceivable.
4. In some cases a complete census is ruled out by the nature of the population. If there is a population that is infinite and/or hypothetical, then sampling is the only option.
5. A sample survey gives data of better quality than a complete census, because in a sample survey it may be possible to use better resources than a complete census.
