Historian’s notes
How the data was madeCompiled by hand from archives in 27 countries over decades, and corrected through user submissions and yearly releases.
Known gaps and biasesThe early Brazilian trade is thin, and illegal voyages after 1807 were deliberately hidden. Estimates are modelled rather than counted, and some values are imputed (marked *).
