This study includes data on slave sales that occurred on the New Orleans slave market between 1804-1862. For each sale, information was recorded on the date of the sale, the number of slaves on the invoice, the geographical origin of the buyer and seller, the sale price, and characteristics of the slaves sold (age, sex, family relationship, and occupation). The information presented for each transaction was obtained from the notarized bills of sale in the New Orleans Notarial Archival Office. These bills often contained information on several persons who were sold in a group or as a "lot." Whenever feasible, sale and personal characteristics of individuals appearing in such groups were entered on separate records. This was usually done when separate sale prices were recorded for each member of the group. When separate prices were not recorded for children sold in a group, information describing those children was attached to the record of a principal slave with whom they were associated on the original bill of sale.

  5. ICPSR constructed several new variables (V25-V34) to describe the fourth through the eighth child in a group, extracting this information from separate data records and entering it on the record of the principal slave. ICPSR also constructed Variable 46, "Index of Individual Price Quotation," allowing identification of those records in which the sale price applies only to the principal slave and not to a group of slaves sold as a lot.


Depending on the period of the sale transaction, either 2.5 percent or 5 percent of the bills of sale for each year were drawn to form the final sample.

2008-08-04 SAS, SPSS, and Stata setup files, SAS and Stata supplemental syntax files, SAS transport (CPORT) files, SPSS system files, and Stata system files were added to this data collection. SDA has been added to the study. Question text has been added to the codebooks. Value labels have been added to the variables. Missing value definitions were created for the following variables: V5, V8, V9, V11, V16, V20, V22, V24, V26, V28, V30, V32, V34, V39.

1984-05-11 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Created online analysis version with question text.
  • Checked for undocumented or out-of-range codes.
