For each sociodemo criterion, two thresholds are computed: quantile threshold value on the criterion and surf intensity threshold. There is no unique answer to the question: how many “male” are there in the database? It depends on quantile and surf intensity thresholds. The lower these are, the higher the number of males is. However, as it is not 100% possible to determine who is accessing content, higher thresholds, although resulting in lower volumes, will result in a better probability of only male users.
