      Determine the total number of people, with the characteristic of interest, in the population that you are surveying. For instance, say that you're surveying the total number of people with buck teeth in the Azerbaijan Islands, and you find that there are 60 such people. Those 60 people make up the total population of people, on the islands, with that characteristic.

      Determine the number of people in the overall population. For example, suppose the people in the islands number 6,000.

      Divide the total number of people with buck teeth by the total number of people in the population to o,btain the fraction of people with buck teeth. Here, dividing 60 by 6,000 gives 1/100.
