On http://www.childinfo.org/ you will find UNICEF's key statistical databases with detailed country-specific information that was used in the end-decade assessment of progress and setbacks in implementing the 1990 World Summit for Children Declaration and Plan of Action. The site contains global and regional summary analyses and graphics of key results, in addition to new and revised data. A new file included graphics for countries that illustrate patterns of infant feeding at different points and time. These graphics allow better understanding of the major issues to be addressed.
