The extent to which the demographics of the sample proportionally match those of the population is the most important feature that should be considered when selecting samples in survey studies. This ensures that the sample is representative of the population and reduces bias in the results. Inclusion of equal numbers of individuals from different groups in the population (A) and the number of people in the sample (B) are important factors, but not as crucial as ensuring a representative sample. The ratio of the sample size to the population size (C) is also important, but it is not the most important feature as long as the sample is representative.
