Millions of children worldwide are migrants or displaced, according to a UNICEF report.
The main reasons for migration are conflict, war, poverty, climate change, the hope of finding a better life, danger, detention, deprivation, discrimination, forced recruitment and a high rate of crime and violence.
Climate change makes it impossible to live in some regions.
As a result of natural disasters, 7.3 million children were displaced throughout 2021, according to the report.
UNICEF said in the past 10 years, the number of refugees worldwide has more than doubled, with children making up nearly half of the total. More than a third of displaced children or 3.9 million or 36 per cent live in Sub-Saharan Africa. Another 2.6 million or 25 per cent in Europe and Central Asia, while 13 per cent, or 1.4 million people, are in the Middle East and North Africa.
Children account for about 28 per cent of trafficking victims globally, according to UNICEF and the Inter-Agency Coordination Group against Trafficking (ICAT).
