Stability of social facts -Structural facts are the most stable types of social facts or social phenomenon.Examples would be the forms of dwellings in a social group or the technologies of communications or even the distribution of the population.-Institutionalized norms are quite stable but not as fixed. They are habits, customs, legal rules, religion dogmas. This is a typology. -Social currents are the least stable types of social facts. It is about movement, fluid, less permanent! An example would be the current of opinion or popular opinion. Or a particular factlike the Pokémon. Transitory outbursts of enthusiasm or a revolution also fit in these social currents.
