Difference between Census and sampling

  1. 1. Difference Between Census and Sampling
  2. 2. Overview: Census and Sampling are methods of collecting data about the Populace. A Sample is a portion and a Census measures everyone in the whole country
  3. 3. What is Census ? A census is the procedure of systematically acquiring and recording information about the members of a given population. Under this method, data is collected for each and every unit viz. person, household, field, shop, factory etc…, as the case may be of the population or universe. For example, if the average wage of workers working in a sugar factory is to be calculated, then wage figures would be obtained by dividing the total wages which all the workers received by no of workers working in the sugar industry.
  4. 4. What is Sampling ? Sampling is simply the process of learning about the population on the basis of a sample drawn from it. In the Sampling technique, instead of every unit of universe only a part of the universe is studied and the conclusion is drawn on that basis for the entire universe. The theory of sampling has taken place only in recent years, the idea of sampling is pretty old. Since times immemorial have examined a handful of grains to ascertain the quality of entire lot. A housewife examines only a two or three grains of boiling rice to know whether the pot of rice is ready or not. a bussinessman places orders for material by examining only a small sample of the same.
  5. 5. Difference :  In Census, each and every unit of the population is studied. but only few units of the population studied is studied in Sampling.  Census refers to periodic collection of information about the populace from the entire population. However, if the next Census is far away, Sampling is the most convenient method of obtaining data about the population.
  6. 6.  Census method demands a large amount of finance, time and labor. Relatively less amount of finance, till labor is required for Sampling.  Results obtained by Census are quite reliable. Results obtained by Sampling are less reliable.  It is more suitable to use Census Method if population is heterogeneous in nature. and It is more suitable to use Sampling Method if population is homogeneous in nature.
  7. 7.  Samples have a margin of error though, which gets lower as the sample size increases. In other words, sampling more people means obtaining better data. Instead, this type of error is not present in Census as each and every part of the geographical area has to be approached for data collection. However, Difference between the Sample result and census result under the same circumstances is known as ‘Sample Error’. and this error can be minimized by taking large samples.
  8. 8. Conclusion : Data collected through census is more accurate because it takes the entire population into account while the data collected through sampling is close to real information but has scope for error because the information is collected from a sample population. This does not mean that data collected through sampling is not important. Both the methods have their own importance and the data collected through tem plays significant role in formulation of policies especially for the weaker sections.
