The 2010 Version of the Trans-Atlantic Slave Trade Database (expanded data set)
TThe 2010 version of the transatlantic slave trade database contains 34,948 voyages
compared to 34,940 in 2008 (and 27,233 in the 1999 version of the database that appeared
on CD-ROM). However, since 2008, several hundred corrections have been made and additional
information added. Thus 86 of the 2008 voyages have been deleted either because we found
they had been entered twice, or because we discovered that a voyage was not involved in
the transatlantic slave trade. Voyage id 16772, the Pye, Captain Adam, turned out to have
carried slaves from Jamaica to the Chesapeake, but obtained its captives in Jamaica, not
Africa. Offsetting the deletions are 94 voyages added on the basis of new information.
Further many voyages that are common to both 2008 and 2010 versions of the database contain
information that was not available in 2008 (see table 1 of “Understanding the Database”).
The 2010 version 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. The 2008 version of the database
may also be downloaded.
The Trans-Atlantic Slave Trade Database (Voyages data set)
This data set of the Trans-Atlantic Slave Trade Database contains the 99 variables
available through the Voyages Database on this website. It is made available in three
formats: SPSS (.sav), comma delimited (.csv), and dBase (.dbf). Users interested in
working with this data set with their preferred software may select an edition year
and file format below.
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.
African Names Database
Between 2008 and May 2012 Voyages offered access to an African Names Database
that identified over 67,000 Africans removed from slave ships in the abolition era,
including their names, age, gender, stature, and place of embarkation. While these
data have been incorporated into the African-Origins site the latter does not include
stature data. The African Names Database is thus made available here in csv format.
