Well these two issues do seem to be a large part of the illegal slavery that does currently occur in US. It also encompasses the agricultural sector affecting immigrants at much higher levels, and women and children. But this is just from the US perspective.

It is my understanding that slavery does still occur in large numbers in India. It is termed bonded labor. I just read "Slavery affects more than 40 million people worldwide – more than at any other time in history" That is a shock to read! Leading areas for slavery in the world currently are in parts of Asia and Africa. It also disproportionately affects the female gender worldwide, though by 8%, so not by a large percentage.

Outside of slavery itself are the effects of government on people. Government controlling human behavior so as to restrict the freedom of the individual to not be who the person chooses to be versus what the state says you should be. If slavery is also thought of in those terms, there is probably much more slavery in the world than there is actual freedom.
