How we can measure the exact sample size, number of interviews, and focus groups discussions for a region whose population is 200,000 for primary research.
One way could be creating or dividing the region in sub-groups, maybe in geographical categories and have representative sample from each sub-group (10%). Focus group can vary based on your research objectives. Hope this helps.
