Peter Blau-space is still used as a guide by sociologists and has been expanded to include areas of sociology never specifically covered by Peter Blau himself.

Peter Blau was very active in the study of structural theory.
Peter Blau's 1977 book, Inequality and Heterogeneity, presents "a macro sociological theory of social structure" where the foundation of his theory "is a quantitative conception of social structure in terms of the distributions of people among social positions that affect their social relations".

Peter Blau died on March 12,2002, of acute respiratory distress syndrome.
Peter Blau began theoretical studies by making a broad statement or basic assumption regarding the social world, which was then proven by the logical predictions it produced.
Peter Blau claimed these statements could not be validated or refuted based on one empirical test.
Peter Blau focused his sociological theory on both the micro and macro level, and often connected the two throughout his research.
Peter Blau believed that population structure created guidelines for specific human behaviors, especially intergroup relations.
Peter Blau created a number of theories explaining aspects of population structure that increased chances of intergroup relations.
Peter Blau viewed social structure as being somewhat stable, but he did identify two phenomena that he believed contributed to structural change within a population: social mobility and conflict.
Peter Blau thought social mobility, which he described as "any movement within a population by an individual," was beneficial to intergroup relations within a population structure, and theorized various scenarios involving social relations and mobility.
Peter Blau theorized explanations for structural causes of conflict, focusing on population distribution as a cause of conflict separate from individual or political issues.
Peter Blau determined that prevention of conflict within a population structure can be achieved through "multi-group affiliations and intersection in complex societies".
Social exchange provides an explanation of the interactions and relationships Peter Blau observed while researching.
Peter Blau believed that social exchange could reflect behavior oriented to socially mediated goals.
Peter Blau started from the premise that social interaction has value to people, and he explored the forms and sources of this value in order to understand collective outcomes, such as the distribution of power in a society.
People engage in social interactions in which we would not think deep about, but Peter Blau suggested it is for the same reason why people engage in economic transactions.
Peter Blau expressed the difference between social exchange and the purchasing of goods, stating that there is an emotional component within social exchange that is nonexistent in everyday transactions.
Peter Blau believed that most thriving friendships occur when both participants are the same status level, allowing for an equal potential for exchange and benefit throughout the relationship.
Peter Blau studied the social exchange of partners, and how these relationships come together in the first place.
Peter Blau explains how loving relationships come to existence through the exchange of certain favorable traits that would attract one person to another.
Peter Blau discusses how status, beauty, and wealth are some of the key characteristics that people search for in a partner, and that the most successful relationships occur when both partners have valuable attributes that they can benefit from.
Peter Blau conducted a different approach in the main subject group for organizational sociology, focusing far more on white-collar workers rather than those of the blue-collar status, concentrating on the relationships between workers.
Peter Blau discussed how the incipient status systems formed were important to the continued functioning of these organizations as the formal status structure.
Hence, much of Peter Blau's work involving organizations centered on the interplay between formal structure, informal practices, and bureaucratic pressures and how these processes affect organizational change.
Peter Blau collected data on 53 Employment Security Agencies in the US and 1,201 local offices.
Peter Blau derived several generalizations, the most important which are increasing size results in an increase in the number of distinct positions in an organization at a decreasing rate, and as size increases the administrative component decreases.
Probably one of the biggest contributions Peter Blau gave to sociology was his work in macrostructural theory.
Peter Blau believed that the root of social structure can be found whenever an undifferentiated group begins to separate itself along some socially relevant distinction.

Peter Blau played an important role in shaping the field of modern sociology and is one of the most influential post-war American sociologists.
Peter Blau is sometimes considered the last great "grand theorist" of twentieth century American sociology.
Peter Blau provided an exemplar of how to do research and how to build theory.
Peter Blau proved that general and valuable deductive theory was possible in sociology.
Peter Blau eventually paved the way for many young sociologists that then used similar styles of research and deductive theory.
