The Trans-Atlantic Slave Trade SPSS Database (expanded data set)
The 2008 version of the Trans-Atlantic Slave Trade Database contains 8,374 voyages
added since the CD-Rom was published in 1999 and additional information on 19,320 voyages.
The expanded data set has 276 variables, compared with 99 in the Voyages Database available
online. Users interested in working with this larger data set can download it in a file
formatted for use with SPSS software. A variable in this dataset (EVGREEN) identifies
voyages on the CD-ROM version published in 1999. Because some users may find it useful
to view data as it existed in 1999, the CD-ROM version can also be selected for download.
A codebook describing all variable names, variable labels, and values of the expanded
dataset can be downloaded as a separate PDF document. With only a few exceptions, it
retains variable names in the original 1999 CD-ROM version.

Estimates spreadsheet
The Estimates section uses data from the expanded Trans-Atlantic Slave Trade Database dataset,
aggregated by regions of embarkation and disembarkation, but also incorporates published series
of embarkations and disembarkations for particular regions when these data provide more accurate
estimates than the database itself. Users interested in exploring the complex methodology involved
in generating the estimates, or in testing the extent to which alternative assumptions lower or
augment estimates of the full volume of the slave trade (in its entirety or for a national carrier
or period of time), can download below an Excel-formatted copy of the spreadsheet estimating the
full volume of the slave trade by national carrier and year of arrival, the SPSS file applying
estimates of volume in the spreadsheet to data on exports and imports aggregated by national carrier,
year of arrival, and the route of the voyage from region of embarkation to region of disembarkation,
and a PDF version of the essay detailing the methodology used.
