There is limited research into the types of crowd and crowd membership and there is no consensus as to the classification of types of crowds. Two recent scholars, Momboisse (1967)<ref>Momboisse, Raymond. ''Riots, Revolts, and Insurrection''. Springfield, Ill. Charles Thomas. 1967. {{ISBN?}}</ref> and Berlonghi (1995)<ref>Berlonghi, Alexander E. "Understanding and planning for different spectator crowds". [[Safety Science]]. Volume 18, Number 4, February 1995, pp.&nbsp;239–247</ref> focused upon purpose of existence to differentiate among crowds. Momboisse developed a system of four types: casual, conventional, expressive, and aggressive. Berlonghi classified crowds as spectator, demonstrator, or escaping, to correlate to the purpose for gathering.

Other sociologists distinguished four types of crowds: casual, conventional, expressive, and acting.<ref name="Blumer">{{cite book |last1=Blumer |first1=Herbert |title=Collective Behavior. |date=1939 |publisher=Barnes & Noble |location=New York |pages=219–280 |edition=In Robert E.

There are also conventional crowds or those that come together for a regularly scheduled event including a church service and expressive crowds that meet to partake in an emotional time together like a wedding or funeral. Lastly, there are acting crowds that join to achieve a common goal or action, which could involve participating in a protest or riot.

Crowds can be active (mobs) or passive (audiences). Active crowds can be further divided into aggressive, escapist, acquisitive, or expressive mobs.<ref name="Ref.3" /> Aggressive mobs, which are common in [[riot]]s, are often violent and outwardly focused. Examples are football riots and the [[1992 Los Angeles riots|L.A. Riots]] of 1992. Escapist mobs are characterized by a large number of people trying to get out of a dangerous situation. Incidents involving crowds are often reported by media as the results of panic.<ref>{{Cite journal |last1=Feliciani |first1=Claudio |last2=Corbetta |first2=Alessandro |last3=Haghani |first3=Milad |last4=Nishinari |first4=Katsuhiro |date=2024-04-01 |title=How crowd accidents are reported in the news media: Lexical and sentiment analysis |url=https://www.sciencedirect.com/science/article/pii/S0925753524000134 |journal=[[Safety Science]] |volume=172 |pages=106423 |doi=10.1016/j.ssci.2024.106423 |arxiv=2309.14633 |s2cid=262824786 |issn=0925-7535}}</ref><ref>{{Cite journal |last1=Haghani |first1=Milad |last2=Lovreglio |first2=Ruggiero |date=2022-12-09 |title=Data-based tools can prevent crowd crushes |url=https://www.science.org/doi/10.1126/science.adf5949 |journal=Science |language=en |volume=378 |issue=6624 |pages=1060–1061 |doi=10.1126/science.adf5949 |pmid=36480619 |bibcode=2022Sci...378.1060H |s2cid=254485601 |issn=0036-8075|url-access=subscription }}</ref> However, the scientific literature has explained how panic is a myth which is used to mislead the attention of the public from the real causes of crowd incidents such as [[Crowd crush|crowd crashes]].<ref>{{Cite journal |last1=Fahy |first1=Rita F. |last2=Proulx |first2=Guylène |last3=Aiman |first3=Lata |date=August 2012 |title=Panic or not in fire: Clarifying the misconception |url=https://onlinelibrary.wiley.com/doi/10.1002/fam.1083 |journal=Fire and Materials |language=en |volume=36 |issue=5–6 |pages=328–338 |doi=10.1002/fam.1083 |s2cid=145326665 |issn=0308-0501 |author1-link=Rita Fahy |url-access=subscription }}</ref><ref>{{Cite journal |last1=Haghani |first1=Milad |last2=Cristiani |first2=Emiliano |last3=Bode |first3=Nikolai W.

An expressive mob is any other large group of people gathering for an active purpose. Civil disobedience, rock concerts, and religious revivals all fall under this category.<ref name="Ref.3" />
