Rates for incidence of child sexual abuse (CSA) by type of abuse.

Study	Penetration	Genital contact	Exposure of genitals to child	Attempted penetration	Exploitation: prostitution or pornography
TYPE OF ABUSE
NIS-1	0.3/1,000	0.2/1,000	0.1/1,000
NIS-2	0.8/1,000	0.9/1,000	0.5/1,000
CIS-1998	0.29/1,000	0.82/1,000	0.21/1,000	0.29/1,000	0.1/1,000
Finkelhor et al. (2005)	4/1,000	32/1,000	4/1,000	18/1,000

This table shows summary data for childhood sexual abuse (CSA) by type (where available) for incidence studies in both the United States National Incidence Studies (NIS) and the Canadian Incidence Studies (CIS), and compares these “above the surface” studies to an incidence study that includes “below the surface” rates (Finkelhor et al., 2005). Note that some studies have reported rates for several types of abuse together and the Finkelhor study did not examine rates for exploitation.
