A hypothetical population assumes the presence of a population that cannot be defined according to sampling theory rules, which require a list of all members of the population. For example, individuals who successfully lose weight would be a hypothetical population. The number of individuals in the population, who they are, how much weight they have lost, how long they have kept it off, or how they achieved the weight loss is unknown. Some populations are elusive and constantly changing. For example, listing all women in active labor in the United States, all people grieving the loss of a loved one, or all people coming into an emergency department would be impossible to identify.
