Nguyen Huu Thanh, head of the province's Social Welfare and Child Protection Division, said most child labourers earned their living by tapping rubber trees, catching fish and selling lottery tickets on the street.
They also work at privately owned factories that produce pottery and bricks and process cashew nuts.
Nearly 50,000 workers and their children migrate to industrial zones in the province every year, he said.
Last school year, a total of 5,497 students dropped out of schools, accounting for 1.24 per cent of the total number of school-age children in the province, according to the division.
Of that figure, junior high schools posted the highest number of drop-outs, with more than 2,800 students, followed by primary schools with more than 400 students, the report showed.
The province was chosen as one of five targeted localities to carry out a four-year pilot project that supports the design and implementation of the National Programme on the Elimination of the Worse Forms of Child Labour.
The project, with a cost of 2.5 million euros (US$3.425 million) and funded by the Spanish Agency for International Development Cooperation, is being implemented by the Ministry of Labour, Invalids and Social Affairs, with technical support and training from the International Labour Organisation (ILO).
Launched last year, the project aims to contribute to the prevention and progressive elimination of child labour in Viet Nam.
It is expected to reach around 5,000 children in five targeted cities and provinces, including Ha Noi and Lao Cai, Ninh Binh, Quang Nam and Dong Nai provinces. — VNS
