The 2016 Version of the Trans-Atlantic Slave Trade Database (expanded data set)
The 2017 version of the transatlantic slave trade database contains 35,942 voyages compared to 34,940 in 2008 (and 27,233 in the 1999 version of the database that appeared on CD-ROM). Since 2008, several thousand corrections have been made and additional information added. Thus 120 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. For example 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 1,110 voyages added on the basis of new information. Further many voyages that are common to both 2008 and 2010 versions of the database now contain information that was not available in 2008 (see table 1 of “Understanding the Database” for the current summary). The 2016 version has 278 variables, compared with 98 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 earlier versions, the database as it was in 1999, 2008 and 2010 can also be selected for download. A codebook describing all variable names, variable labels, and values of the expanded dataset is available as a separate PDF document. With only a few exceptions, it retains variable names in the original 1999 CD-ROM version.

The Trans-Atlantic Slave Trade Database (Voyages data set)
This data set of the Trans-Atlantic Slave Trade Database contains the 98 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
This database contains personal information of 91,491 Africans taken from captured slave ships or from African slave trading sites after 1807 as a result of the British navy’s attempt to suppress the slave trade. It includes names, stature, sex/age category, country of origin, the name and database id of the slave vessel involved, year of arrival, and ports of embarkation and disembarkation. These variables may be searched on the African Names Database page of the present site. They have also been incorporated into African-Origins.org that provides in addition opportunities to view and contribute to the ethnolinguistic identification of the African names.
