Quota (Quota method)

Definition: A quota (also called a quota method) is a methodology used to select samples for a study. The quota method ensures that the sample is representative of the population, in the form of groups of individuals with specific characteristics (age, gender, income, education level, socio-professional category, political opinion, etc.).

If the readers of a website on the world of fashion are women aged 25 to 35 aiming in urban areas and they represent 5% of the French population; then, in the context of a study on a sample of 1000 people, this quota of potential readers will represent 50 people.
