Urban India is employing an increasing number of children – many under 9 years old – in producing everything from pickles to fireworks, working in tourism and laboring on building sites, a U.N. children’s agency report and campaigners said. The State of Child Workers in India report by UNICEF, based on the latest Indian census data, says the proportion of child workers in the 5-to-9-year age group jumped to 24.8 percent in 2011 from 14.6 percent in 2001.
