This data visualization is by the organization Anti-Slavery, and is the FastCo Design infographic of the day. A more detailed explanation of Brazilian forced child labor explains:
Poor labourers in Brazil can be tricked into forced labour on rural estates in the Amazon region. They are told they must repay inflated transport and food costs to their employers. The isolation of these areas is enough to stop them trying to escape, but armed guards can also be used. The Government has mobile inspection units and has freed many people from slavery. They also have a “dirty list” of individuals and companies found to be involved in slave labour, which can be stopped from receiving credit from the Government-run Bank of Brazil.
Policy organizations like Transparency International and the World Bank have done a great job of helping to visualize old problems like corruption and economic growth in new ways. By marrying solid, cited information like the quote above with a visual representation, we can make policy advocacy more compelling to more people.
