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 (about 1 in 2 children worldwide) 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. Definition The definition of children in most countries is "people under the age of eighteen". Culturally defining the end of childhood is more complex, and takes into account factors such as the commencement of work, end of schooling and marriage as well as class, gender and race. According to the United Nations Children's Fund (UNICEF) "children living in poverty are those who experience deprivation of the material, spiritual and emotional resources needed to stay alive, develop and thrive, leaving them unable to enjoy their rights, achieve their full potential, and participate as full and equal members of society". The ChildFund International (CFI) definition is based on Deprivation (lack of materialistic conditions and services), Exclusion (denial of rights and safety) and Vulnerability (when society can not deal with threats to children). Other charitable organisations also use this multi-dimensional approach to child poverty, defining it as a combination of economic, social, cultural, physical, environmental and emotional factors. These definitions suggest child poverty is multidimensional, relative to their current and changing living conditions and complex interactions of the body, mind and emotions are involved. Measuring child poverty The easiest way to quantify child poverty is by setting an absolute or relative monetary threshold. If a family does not earn above that threshold, the children of that family will be considered to live below the poverty line. Absolute poverty thresholds are fixed and generally updated only for price changes, but relative poverty thresholds are developed with reference to the actual income of the population and reflect changes in consumption. The absolute poverty threshold is the money needed to purchase a defined quantity of goods and services, and every threshold generally reflects the minimum income required to acquire necessities of life. However, a caveat is that as a family that earns above a set threshold may still choose
