Macro social work includes efforts that help communities and other large groups. This may include deciding which programs to make available in a particular area, conducting research on the needs of a region, and helping implement large interventions to change the character of a region. This is the broadest type of social work and emphasizes systems and processes over working with individual people. Macro social work should not be confused with the two other types of social work: mezzo and micro. Mezzo social work focuses on neighborhoods, small groups, and companies, while micro social work focuses on individuals and families. These three levels are not mutually exclusive because what happens in one usually affects the others. Given the scope and duties of this position, macro social workers often work for city governments, healthcare organizations, or related companies.
