Bronfenbrenner's ecological model conceptualizes a young person's development within multiple environmental systems, ranging from their immediate environment to broader societal influences. These systems include the microsystem of close relationships, the mesosystem of connections between microsystems, the exosystem of social settings not directly experienced but still affecting the person, the macrosystem of encompassing cultural values, and the chronosystem of environmental changes over time. Each system interrelates in impacting a youth's development over the lifespan.

Bronfenbrenner’s model is a series of nested contexts:
 The microsystem is the innermost system; it contains people and settings that
directly involve a young person, such as their home, family, peer group, work, or
school.
 A mesosystem is an interaction or connection between two or more entities in
the microsystem — for instance, parents visiting school, or friends visiting the
young person’s home.
 The exosystem contains settings that do not directly involve the young person,
but that may still affect their life. For instance, a child may never visit their
parent’s workplace, but events that occur there may affect the child indirectly.
 The macrosystem involves patterns and characteristics of a culture, like a
community or society’s norms and values that shape and affect the youth
experience.

2.  The chronosystem represents the passage of time, focusing on changes in the
youth’s environment. Changes in family structure, socioeconomic status, and
residency can greatly impact developmental outcomes.
Each of these systems interrelate and interact with one another, demonstrating the role
of environmental factors in a young person’s development over time.
