A generation can be defined as a group of individuals of the same age, sharing the same values, the main ones of which were formed around the age of 20. Its definition is flexible, as not all observers agree on defining a specific generation. The concept of generation is the basis of the generational approach, which goes beyond an analysis simply focused on age by highlighting the connections that exist due to living the same life story at the same time, being shaped by formative experiences in one’s youth, and inheriting the values ​​passed down by previous generations. The generational approach is also used by the business world and organizations, particularly in the context of human resources and marketing activities.
