Wedge-capped capuchins live in groups ranging from as few as 5 individuals to more than 30 individuals.
 The groups generally consist of one reproductively active adult male, several adult females and their offspring, and, in some cases, non-reproductive adult males.
 Juveniles generally make up about 50% of a groups population.
The population structure is heavily skewed toward females.
 There are approximately 2 females to every male at birth.
 This ratio increases to more than 4 adult females for every adult male.
 This is the result of both female-biased birth ratios and male migration behavior.

Birthrate in wedge-capped capuchins varies with age.
 Younger and middle-aged females (6 to 26 years old) give birth as often as once every two years.
 Older females (older than 26 years) may only give birth once every three or four years.
It is important to note that both male and female wedge-capped capuchins live as long as 36 years.

In wedge-capped capuchins, males emigrate from their natal groups while females generally remain in the same group for the majority of their lives.
 Males generally leave their natal group between 3 and 6 years of age.
 Young males spend little time alone after leaving their natal groups and quickly integrate into a new group.
 Males prefer to join groups with a high ratio of females to adult males, as this maximizes their probability for future mating success.
 Immigrating males generally meet little opposition when joining a new group.
 Older females may migrate to new groups on rare occasions.
