More than 35,000 people were rescued from slave labour in Brazil over the past 15 years, but over 600 of them ended up in similar conditions at least a second time.
This means that 1.73 per cent of the 35,341 workers rescued from slavery in the country between 2003 and 2017 ended up in slave labour at least for a second time. Twenty-two of those were rescued three times and another four were rescued four times.

Workers who have difficulties accessing public services, particularly education, find themselves more vulnerable to exploitation and slave labour. The likelihood of a person returning to slave labour is greater among those with a low level of education, and the rate among illiterate workers is double that of those who finished primary education.

The Digital Observatory of Slave Labour in Brazil, a joint project by the ILO and the Brazil Federal Labour Prosecution Office, has issued new data on slave labour in the country.
