Disadvantages of sample survey over census​

Answer:

Disadvantages of Sample Surveys compared with Censuses:

Data for small geographical areas ALSO may be too unreliable to be useful.

(Because of the above reasons) detailed cross-tabulations may not be practical.

Disadvantages of Surveys

Inflexible Design. The survey that was used by the researcher from the very beginning, as WELL as the method of administering it, cannot be changed all throughout the process of data gathering. ...

Not Ideal for Controversial Issues. ...

Possible Inappropriateness of Questions.
