Nobody knows whose figures they are, Teribus; you keep on neglecting to tell us.
In a source list, yes I would agree. Why would you only type it that way for one author, and not for the rest?

To compare Arab and English Slave trading, surely one must have the perameters equal.
Your accounting for an extra seven hundred and eighty-three (and three quarters) years is not making comparison possible, except in 'Slaves/Year' terms.
You, yourself pushed that proposition forward, so maybe your auntie does have balls, after all.

Damn sight more than you have, by the sounds of it.

Documented evidence, please Teribus.
So far what we have gleaned from our excursions down the statistics road is, that England mechanised the Slave trade, with a whopping 11.6 million units processed in 360 years.

No wonder Blair nearly said sorry.
