Culture is learned from the people surrounding us, our parents, guardians, relatives, etc. The distinct set of beliefs, values, traditions and behavior is passed down through generations. It is a collective phenomenon, and cannot exist in isolation in a single individual. It is shared at various levels, namely national, regional, gender, generation, corporate, social class, etc., but is also rich in diversity. Residents of a nation share certain aspects, whereas different regions within the nation have their own unique blend of beliefs, values and styles, and so on.
Culture is cumulative and dynamic. The culture of any particular group is constantly evolving and undergoing slow changes. Each generation brings along a new set of changes and developments in the culture of that society. Moreover, long-term exposure to different cultures leads to the exchange of certain cultural aspects.
