Percentages will add up to 100 unless the categories are not mutually exclusive. In gender statistics, proportions can be calculated as relative measures of (a) distributions of each sex by selected characteristics, and (b) sex distributions within the categories of a characteristic. These two types of proportions are presented in the table IV. In the first case of distribution, the proportions are calculated as relative frequencies of the categories of a characteristic for each sex, with womens and men’s respective totals used as the denominators. For example, in the third column of data in table IV. This is calculated as the number of women employed divided by womens total population in the corresponding age group and multiplied by 100.
