Series Information
The 2004 Population and Housing Census was a de facto enumeration. It was the fourth national population census, being preceded by national censuses in 1963, 1974 and 1985. The long interval between the 1985 and the 2004 population censuses has been mainly attributed to the 10 year brutal civil war.
Abstract
The last census that was held in Sierra Leone was in 1985 and according to normal procedure, there should have been another census in 1995 but due to the eleven-year war, it was not possible and the 1985 census data had become completely obsolete and needed to be updated. Therefore the main objectives of the 2004 population and Housing Census were:
· To help ensure the availability of a time series of population data to support socio-economic development planning and population programs as well as to contribute to the development of national capacity for statistical enquiries.
· Continue the regular pattern of the conduct of censuses in Sierra Leone as a continuing scheme of statistical data collection.
· Provide information on housing conditions in the country after the eleven-year war.
· To help ensure the availability of a time series of population data to support socio-economic development planning and population programs as well as to contribute to the development of national capacity for statistical enquiries.
· Continue the regular pattern of the conduct of censuses in Sierra Leone as a continuing scheme of statistical data collection.
· Provide information on housing conditions in the country after the eleven-year war.

Data Collection Mode
Face-to-face [f2f]
Supervision
Interview was conducted by teams of interviewers. Each interviewing team comprised of 4 interviewers and a driver, under the supervision of 1 supervisor.
The role of the Supervisor was to coordinate field data collection activities, including helping the District Training Coordinator; the District Census Officer and the Field Officer in training the Enumerators; arrange for the enumeration of special population groups such as institutions, floating population, nomadic population etc.; maintain good relations with the public; ensures that the enumeration is carried out in all the EAs assigned, close supervision of the Enumerator's work, editing of enumerator's completed questionnaires for completeness and any inconsistencies; conduct random checks in a sample of households in their assigned EAs to ensure that interviews are actually conducted in them; return all questionnaires, whether used, spoilt or unused, and all other returnable materials to their Field Officers and to ensure that Enumerators are paid upon satisfactory completion of their assignment. Additionally, the District Census Officers sent a monthly progress report to the Central office. The Field Officers were responsible for reviewing each questionnaire at the end of the day, checking for missed questions, skip errors, fields incorrectly completed, and checking for inconsistencies in the data. The Field Officers also observed interviews and conducted review sessions with interviewers. Field visits were also made by Census Technical Coordinators on a periodic basis during fieldwork. Senior staff (the Chief Census Officer, the Director of Census, the GIS Officers, the Census Program Manager) also made visits to field teams to provide support and to review progress.

Data Collection Notes
The data collection involved house-to-house visits by trained enumerators using questionnaires prepared and tested during the preparatory phase. Special arrangements were made for the coverage of inmates of institutions and special population groups such as the homeless, transients and refugees. The enumeration lasted for two weeks beginning in the first week of December 2004.

Questionnaires
Questionnaires
The questionnaires for the 2004 Population and Housing Census were structured questionnaires based on the 1985 Population Census Questionnaire with some modifications and additions. A household questionnaire was administered in each household, which collected various information on household members including sex, age, relationship, and orphan hood status. The housing module questionnaire includes household characteristics; the population module questionnaire includes sex, age, relationship, religion, nationality, ethnicity/primary/secondary language, disability, education, marital status, the deaths module includes cause of death (Malaria, Malnutrition, Hypertension, Anemia, Acute Respiratory Infection(ARI), Bronchopneumonia, Maternal Death and others), age at death and sex; the agriculture module includes number of livestock owned by household members, access to agricultural facilities, In addition to a household questionnaire, questionnaires were administered for every member in each household throughout the country. The questionnaires were developed in English and were reviewed by the Census Technical Committee/Stakeholders.
Data Processing
Data Editing
Data editing took place at a number of stages throughout the processing, including:
a) Office editing and coding
b) During data entry
c) Structure checking and completeness
d) Secondary editing by data entry supervisors
e) Structural checking of SPSS data files by statisticians.
Data entry was conducted by 60 data entry operators in two shifts, supervised by 20 data entry supervisors, using a total of 60 computers (plus one supervisors' computer). All data entry was conducted at the Statistics Sierra Leone Headquarters using manual data entry. For data entry, IMES version 3.0 was used with a highly structured data entry program, using system controlled approach that controlled entry of each variable. All range checks and skips were controlled by the program and operators could not override these. A limited set of consistency checks were also included in the data entry program.

1) Questionnaire reception
2) Office editing and coding
3) Data entry
4) Structure and completeness checking
5) Verification entry
6) Comparison of verification data
7) Back up of raw data
8) Secondary editing
