Data Release Policy
March 31, 2011
As part of the USDOL-Tulane contract, Tulane University was tasked with conducting annual, nationally representative surveys of child labor in the cocoa growing areas of Côte d’Ivoire and Ghana that yield information on household demographics and socioeconomic status; estimated number of children working in the cocoa sector; working conditions of children on cocoa farms; origin and mode of recruitment of hired child labor; as well as school attendance of children in the cocoa growing areas. Tulane’s first survey of child labor in the cocoa growing areas was implemented during the cocoa harvest season in 2007 in Côte d’Ivoire and Ghana (Nov 2007-Dec 2007). A second follow-up survey followed in the 2008/09 harvest period (Nov 2008-Jan 2009). In the last quarter of 2009, Tulane carried out an additional survey of child migration and trafficking for work in cocoa agriculture with data collection in Burkina Faso and Mali.
The data files from this survey research are made available free of charge to registered users. Due to the sensitive nature of some of the survey questions and in order to ensure the protection and confidentiality of the child and adult respondents, potentially identifying information has been modified or removed from the data sets. The following changes and modification have been made:
1. Questionnaire Identifiers – Questionnaire identifiers created for the purpose of sampling and field data supervision are not released (including the interviewer names, household listing information, etc.).
2. Names and Contact Information of Respondents – The names and contact information of the survey respondents have been removed from the data sets. This includes addresses and telephone numbers.
3. Names and Contact Information of Individuals Identified by Respondents – The names and contact information of individuals identified by the respondents have also been removed. This includes all indicators that directly identify another member of the respondent’s household. This also includes the names and contact information of other individuals identified by the respondents (including, but not limited to, individuals identified as part of the snowball sampling process).
4. Village Names and Other Geographic Information - Some geographic information has been removed including information on the census enumeration areas/districts in which the data were collected, the names of the villages and settlements in which the research was carried out, and administrative identifiers below regional level.
5. Age Information – The following modifications have been made to the age information provided by the survey respondents. Age information collected as part of the Household Interview, the Head of Household/Caregiver Interview, and the Child Interview has been re-coded into intervals. The following age brackets have been created:
Age information is not released for the respondents included in any of the smaller data sets.
6. Information on Ethnic Group, Religion, Nationality & Country of Birth – The following modifications have been made to the indicators measuring ethnic group, religion, nationality and country of birth to protect minorities among the survey respondents. For Household Interview, Head of Household/Caregiver Interview and Child Interview, all ethnic groups, religions, nationalities and countries of birth represented by fewer than 10 respondents have been re-coded as “88" or "Other.” Information on ethnic group, religion, nationality and country of birth is not provided for any of the smaller data sets.
7. Additional Data Sets – In addition to the large household surveys, Tulane collected data from smaller samples of key informants. These data sets are released if a minimum number of respondents has been interviewed (10 or more respondents per data set) and if through the removal of (a) names and contact information, (b) village names and administrative identifiers below regional level, and (c) key demographic information (age and gender of respondent, ethnic group and religion, citizenship and country of birth as well as work history and educational background characteristics) the confidentiality of the respondents can be ensured.
The following data sets are released: Community Leader Interviews (except those conducted at border crossings), Adult Worker Interviews, Teacher Interviews, Interviews with School Children, Health Center Interviews, Project Interviews , Cocoa Shed Interviews, Cocoa Depot Interviews, Infrastructure Checklists, Interviews with Children with Migration or Trafficking Experience to a Cocoa Farm, and Interviews with Caregivers of Children with Migration or Trafficking Experience to a Cocoa Farm (Burkina Faso only).
The following data sets are not released: Border Guard and Law Enforcement Interviews as well as Community Leader Interviews conducted at border crossings in Burkina Faso and Mali. Due to the small size of the sample, the data from the Interviews with Caregivers of Children with Migration or Trafficking Experience to a Cocoa Farm collected in Mali will also not be released. Similarly, the data collected as part of the Project Interviews in Côte d'Ivoire will not be made publicly available due to the small number of respondents in this sample.
