Market Research is an old science, sample sizes are calculated using a statistically tested method which is accepted the world over basis a perfectly random sample. In fact, the American Presidential satisfaction survey is done on a total of 1000 respondents only.
Here are some sample sizes for a population of 1 crore depending on the confidence level and margin of error desired.
Even if the population grows 10 fold, i.e to 10 crore, these numbers will not change. If you would like to read more about this. Here is a paper from Colmbia University New York: http://www.stat.columbia.edu/~gelman/stuff_for_blog/chap20.pdf You can even try this yourself by using the calculator here: https://www.surveysystem.com/sscalc.htm
We currently offer three levels, 1000, 2000 & 3000 samples. The first two broadly correspond with 95/3 and 99/3 levels of confidence described above and the third is given in case you would like to assess with a larger sample
We have in our database crores of people across 10 states (with more states coming soon).
We sequentially dialled numbers and got people to opt-in to be part of the study.
As a rule, we do not call people who are part of the NDNC registry.

All questions submitted for a survey are put through a moderation process. We listen to all questions submitted on our system. We may refuse to run a survey for several reasons, not limited to inappropriate language, incomprehensible wording or for any reason we feel that the question may not yield you results.
In the event we choose to reject a question, we will refund your credits.
The moderation process is to protect
If we find something wrong in the survey, we will call you, clarify and then approve the survey for execution. We can even replace the audio recording (in consultation with you) if required.
If you still have questions on the moderation process, do write in to us at email@example.com
Every survey goes through a moderation process. If the survey has not yet been moderated, you can cancel it from within Prashnam. Just go the campaigns screen and stop it. If it has entered the moderation process, then there is nothing we can do, as the process is fully automated.
Rest assured though, we hear every question (for your protection and ours) and do a sanity check before letting the survey proceed.
Surveys once approved and/or completed are not eligible for a refund. Please read our refund policy for more information.
Unused credits are eligible for a refund. You may contact us at firstname.lastname@example.org for details on how to get this done.
