Professor Kevin Bales, co-founder of Free the Slaves, explains to Max Foster how his organization calculates the total number globally - and says 30 million is a conservative figure.
Bales examines how different countries face the problem, and explains why Brazil is setting the best example.
Ranking behind illegal drugs and arms trafficking, human trafficking is estimated to be the third largest international crime industry, according to the United Nations Office on Drugs and Crime. It is believed to generate profits of an estimated $32 billion, according to a 2005 report from the International Labour Organization. Of that number, $15.5 billion is made in industrialized countries.
Between 14,500 and 17,500 people are trafficked into the U.S. each year, according to a 2005 report from the U.S. State Department.
According to a United Nations report, the recruiter in 54 percent of human trafficking cases was a stranger to the victim. In 46 percent of the cases, the recruiter was known to the victim. The U.N. report said that the “majority of suspects involved in the trafficking process are nationals of the country where the trafficking process is occurring.”
Globally, some 600,000 to 800,000 people are trafficked across international borders each year, according to a 2007 report from the U.S. State Department. Of that number, more than 70% are female and half are children. However, a 2009 United Nations report stated that around 20% of all trafficking victims are children.
The average price of a slave has decreased during the past 200 years, according to Kevin Bales, a leading abolitionist who has written several books about modern-day slavery.
In 1809, the average price of a slave was $40,000 when adjusted to today’s money. In 2009, the average price of a slave was $90, Bales says.

Slavery still exists. Of that there isn’t much dispute, if any. But how widespread is what many experts call modern-day slavery?
Estimates range from about 10 million to 30 million, according to policymakers, activists, journalists and scholars.
The International Labour Organization, an agency of the United Nations that focuses on, among other things, labor rights, put the number at a “minimum estimate” of 12.3 million in a 2005 report.
Kevin Bales, a sociologist who serves as a consultant to the United Nations and has authored several books about modern-day slavery, estimated the number was 27 million people in his book “Disposable People: New Slavery in the Global Economy.” The book was published in 1999.
There is yet another estimate. Siddharth Kara, a fellow on trafficking at Harvard University and also an author, recently told CNN that his calculations put the range between 24 million and 32 million. That number was current as of the end of 2006, he said.
There are several reasons behind the variance in numbers, said Ben Skinner, who published a book about modern-day slavery – “A Crime So Monstrous: Face-to-Face with Modern-day Slavery.”
“There are two big problems with the count,” Skinner, a Senior Fellow at the Schuster Institute for Investigative Journalism at Brandeis University, said during a telephone interview. “The first is that the people we are counting are, by definition, a hidden population.
“The second problem is more of a theoretical one where the definitions are not in place. We don’t have a common definition still as to what slavery is.”
