Peter Blau was the first to map out the wide variety of social forces, known as “Blau Space”. Blau-space is still used as a guide by sociologists in many areas of sociology. Peter Michael Blau also contributed to social exchange theory and conducted major empirical investigations of occupational structure and the structure of business organizations.

Peter Michael Blau believed that population structure created guidelines for specific human behavior, especially intergroup relations. Blau thought social mobility was beneficial to intergroup relations within a population structure, and theorized various scenarios involving social relations and mobility.

According to Peter Michael Blau, structural conflict is linked to the inequality of status of groups, size of group, and social mobility between groups.
