It also depends on the context and the purpose of the survey. With a sample size of n=1000, you can get a general sense of the population’s opinions or characteristics if the sample is representative of the population and the survey is well-designed. However, larger sample sizes may be needed if you want to make inferences with more precision or if your population is very diverse, or if you want to drill into sub-segments within the population that may be niche and hard to reach (e.g., minority ethnic groups).
In that article. I am saying religious groups have niche minorities similar to minority ethnic groups.
The survey isn’t about the “niche” subset of the population that is religious. It is about the composition of the entire population. Not a subset of the population so that isn’t relevant.
Edit: to be clear, I understand that there may be some niche subsets within this survey that may not be represented because there are only 20 people in the US that believe in that weird religion, but again, that has nothing to do with the larger, non-niche subsets which are absolutely represented with enough accuracy to draw statically significant conclusions with a sample size of 1000
