David Finkelhor, Heather Turner, Richard Ormrod, Sherry Hamby, and
Kristen Kracke ....The survey confirms that most of our society's
children are exposed to violence in their daily lives. More than 60
percent of the children surveyed were exposed to violence within the
past year, either directly or indirectly (i.e., as a witness to a
violent act; by learning of a violent act against a family member,
neighbor, or close friend; or from a threat against their home or
school) (for full details on these and other statistics cited in this
Bulletin, see Finkelhor et al., 2009). Nearly one-half of the children
and adolescents surveyed (46.3 percent) were assaulted at least once
in the past year, and more than 1 in 10 (10.2 percent) were injured in
an assault; 1 in 4 (24.6 percent) were victims of robbery, vandalism,
or theft; 1 in 10 (10.2 percent) suffered from child maltreatment
(including physical and emotional abuse, neglect, or a family
abduction); and 1 in 16 (6.1 percent) were victimized sexually. More
than 1 in 4 (25.3 percent) witnessed a violent act and nearly 1 in 10
(9.8 percent) saw one family member assault another. Multiple
victimizations were common: more than one-third (38.7 percent)
experienced 2 or more direct victimizations in the previous year, more
than 1 in 10 (10.9 percent) experienced 5 or more direct
victimizations in the previous year, and more than 1 in 75 (1.4
percent) experienced 10 or more direct victimizations in the previous
year.
Reports of lifetime exposure to violence were generally about one-
third to one-half higher than reports of past-year exposure, although
the difference tended to be greater for less frequent and more severe
types of victimization. (For example, more than three times as many
respondents reported being victims of a kidnapping over their
lifetimes as did in the past year.) Nearly seven in eight children
(86.6 percent) who reported being exposed to violence during their
lifetimes also reported being exposed to violence within the past
year, which indicated that these children were at ongoing risk of
violent victimization. The reports of lifetime exposure also indicate
how certain types of exposure change and accumulate as a child grows
up; nearly one in five girls ages 14 to 17 (18.7 percent) had been the
victim of a sexual assault or attempted sexual assault, and more than
one-third of all 14- to 17-year-olds had seen a parent assaulted.
