When estimating the sample size for a proportion, the sample size required is always larger when the proportion being estimated is closer to 0.50. This is because as the proportion approaches 0 or 1, it becomes easier to estimate with a smaller sample size, whereas proportions closer to 0.50 are more uncertain and require a larger sample size to achieve a given level of confidence and sampling error.
