The survival and development prospects of Cambodia's children are being seriously

hampered by a lack of research according to a new report from UNICEF called "The

Progress of Nations".

The report says the true levels of malnutrition and death among Cambodian children

under five are not known and says the absence of such figures makes it difficult,

"if not impossible", to gauge the social well-being of the society as a

whole.

What is known is that only 34 percent of Cambodian children under one are immunized

against measles, which ranks the country second only to Laos at 20 percent.

North Korea comes top with 99 percent.
