Child poverty refers to the state of children living in poverty and applies to children from poor families and orphans being raised with limited or no state resources. UNICEF estimates that 356 million children live in extreme poverty. It's estimated that 1 billion children lack at least one essential necessity such as housing, regular food, or clean water. Children are more than twice as likely to live in poverty as adults and the poorest children are twice as likely to die before the age of 5 compared to their wealthier peers.
