Some 40,000 aged between 15 and 29 from the Cidade de Deus (City of God) community are to get assistance from a government initiative sponsored by the Inter-American Development Bank (IDB).
"We want to give a opportunity ... To those who never had one," explained Morgana Eneile, who coordinates the Caminho Melhor Jovem (better path for youth) program.
The Rio state government is weighing in with USD 24 million to add to a USD 60 million grant from the IDB, organisers said.
The program was first tested two months ago in another "pacified" Rio slum, Manguinhos, and now is being rolled out on a larger scale.
"Constructing a new life is a long-term task -- up to two years. Youth will be the protagonist of this story," Lino Rocca, the director of the Manguinhos unit, said in a statement.
