Child maltreatment deaths in the USA

United States government data on child maltreatment deaths
The U.S. government keeps statistics on child abuse in America. Each year, the Administration for Children and Families (ACF), within the department of Health and Human Services, publishes a report. The most recent figures cover the period 2005-2006. A breakdown of maltreatement deaths – State by State – is available here:
http://www.acf.hhs.gov/programs/cb/pubs/cm06/table4_1.htm
On average, there were 2.04 deaths per 100,000 children in 2006. The map shows the 16 States with more than the average number of maltreatment deaths. Texas had the highest fatality rate at 3.96 per 100,000. Ten of the States are in the Bible Belt — an informal term for American States where socially conservative Evangelical Protestantism is a dominant part of the culture, an area covering the Southern States and Missouri.

Update – Data for 2007.
At the beginning of April 2009 the Administration for Children and Families released its report for 2007. Child maltreatment deaths had increased to 2.35 per 100,000 children, on average. Once again, there were 16 States with more than the average number of maltreatment deaths. Colorado had the average number, but the rate in Mississippi had increased, resulting in 11 Bible Belt States with more than the average number of maltreatment deaths. The rankings had changed. Kentucky had the highest fatality rate at 4.08 per 100,000 children. You can see the latest figures here:

United Nations data on child maltreatment deaths
The UNICEF Innocenti Research Centre publishes reports analyzing the performance of the wealthy nations of the OECD in meeting the needs of their children. Report Card No.5, “A league table of child maltreatment deaths in rich nations”, revealed that only two member nations exceeded 2 maltreatment deaths per 100,000 children: The United States of America and Mexico.
Figure 1a in the report shows the annual number of deaths from mistreatment of children under the age of 15 years averaged over a five year period and expressed per 100,000 children in the age group. The USA and Mexico were bottom of the league.

Figure 1b combined data for deaths from ‘purposely inflicted’ violence with deaths classified as ‘of undetermined intent’. The rankings changed somewhat as a result. At 3.7 per 100,000 Portugal had the highest combined figure. Once again, of the remainder, only the United States of America and Mexico exceeded 2 child deaths per 100,000.
