What causes Anomie or an anomic state? and is there more than one cause of Anomie?

Anomie from the Durkheim Archive
http://durkheim.itgo.com/anomie.html

Durkheim identifies two major causes of anomie: the division of labor,
and rapid social change.  Both of these are, of course, associated
with modernity.  In the literature the focus tends to be on rapid
change experienced by individuals either up or down the social
structure.  Here let us focus again on the division of labor.  The
individual in modern society is confronted with a variety of groups
that have different values and goals, each of which competes for the 
individual's allegiance.
