For more than 53 years, UNICEF has been helping governments, communities and families make the world a better place for children. Part of the United Nations system, UNICEF has an enviable mandate and mission to advocate for children's rights and help meet their needs. UNICEF now works in 161 countries, areas and territories on solutions to the problems plaguing poor children and their families and on ways to realize their rights. Its activities are as varied as the challenges it faces, encouraging the care and stimulation that offer the best possible start in life, helping prevent childhood illness and death, making pregnancy and childbirth safe, combating discrimination and cooperating with communities to ensure that girls, as well as boys, attend school.
