It depends on the reading profile of your population
See a study in school chindren in Canada.
In this population 71% of them were readers

You need figure out what the effect size you are trying to establish is, if it is a large effect size, you will be able to get by with a small sample revealing what the statistical probability of being representative of the whole sample.
Maybe you are sampling to get an idea of reading categories, so you have a similar issue, more categories, the larger the sample to reach statistical significance. I wish I could give you a solid answer, but the sample size is as much driven by effect size as it is by size of the total population.
