Of the estimated 2.2 billion children worldwide, about a billion, or every second child, live in poverty. Of the 1.9 billion children in developing nations, 640 million are without adequate shelter; 400 million are without access to safe water; 270 million have no access to health services. In 2003, 10.6 million children died before reaching the age of five, which is equivalent to the total child population of France, Germany, Greece, and Italy. 1.4 million die each year from lack of access to safe drinking water and adequate sanitation while 2.2 million die each year due to lack of immunizations.
