Chilld Labour Survey 2000

Training
Training was organised at the national and zonal levels for the
personnel who participated in the main survey.
National training
The trainees at the national level consisted of three categories of
officers whose roles were crucial to the successful implementation of
the survey, namely: Trainers at the zonal level, Fieldwork monitoring
officers and Data processing officers.

Zonal level training
The training was organized in six states, representing the six geopolitical
zones of the country. The beneficiaries of the zonal training
were field staff and coordinators of the Federal Office of Statistics (FOS)
comprising of enumerators, interviewers, supervisors, state officers,
zonal controllers and state statistical agencies.

Fieldwork organization and monitoring level officers
Data collection (Team Arrangement)
The FOS permanent field staff that were resident in the enumeration
areas were responsible for data collection during the survey. For the
household component, each household head or a responsible adult in
the household gave information about the household in general, while
the children supplied information about themselves. For the street
children component, the field staff, equipped with information obtained
from members of NURTW and others, visited identified vicinities to
locate and interview the children.
The field staff consisted of enumerators, interviewers and supervisors.
The field coordination team was composed of the State Officers and
Zonal Controllers. The State Officer in each state coordinated all field
operations, while the Zonal Controllers in each zone supervised and
coordinated the states in their zones.
The field staff in each state were constituted into three roving teams.
Each team was made of two enumerators and a supervisor. A team
covered 20 EAs in 40 days. In other words, 1 EA was covered in 2 days
including inter EA travels. The same team of two enumerators and one
supervisor also interviewed between 67-134 street children in each
state in about 7-14 days. In other words, a team interviewed an
average of 10 street children in a day.

Supervision and state quality control
In order to ensure authenticity of collected data, the supervision and
monitoring of field operation were carried out at three levels. Firstly, the
supervisors of the roving team promptly corrected errors while still within
the EA. Secondly, the State Officer visited the field staff occasionally in
order to monitor their operations, crosscheck and endorse the
completed questionnaires. The Zonal Controller who crosschecked the
completed questionnaires submitted to him by the State Officers under
his jurisdiction carried out the final level of supervision. To improve the
alertness of the field team, the Zonal Controller occasionally visited
some of the states.

Supervision and national monitoring
In order to enhance the quality of data collection, a monitoring strategy
was devised for members of the technical team from FOS headquarters
and other stakeholders, namely; CBN, FMEL&P, NMB, NpopC and NDE

Data retrieval
The completed and thoroughly edited questionnaires were submitted by
the Supervisors to the State Officers who in turn sent them to their
Zonal Offices for onward transmission to Lagos Head Office.
Data processing
Manual editing
The subject matter staff at the headquarters office carried out the
manual editing of the completed questionnaires retrieved from the 36
states of the federation including FCT, Abuja. The manual editing was
carried out in order to effect final corrections on errors detected on the
completed questionnaires. Such errors included omission,
inconsistencies, double entries, impossibility as well as transcription and
calculation ones.
Data entry/analyses
The staff of Computer Management and Information Services (CMIS)
carried out the entry of the edited questionnaires, running programmes
to further detect inconsistencies and other related errors as part of final
editing. Tables were produced from the analyses.
