It was the third one since Independence. Records show that a census was taken in 1881, 1944, 1951, 1963, 1973, 1983 and 1993."},"study_info":{"abstract":"The objectives of the census are to count all the people in the country and to provide the Government with their number in each Local Government Area and District, by age, sex and several other characteristics. These figures are required for various aspects of economic and development planning. The ultimate aim of such planning is to provide a better way of life for the people of The Gambia, and to conquer what have been called the Five Giants: Disease, Ignorance, Squalor, Idleness and Want. For effective direction of the census field operations, a Divisional Census Office in each Local Government Area Headquarters was opened. Each of these Divisional Offices was headed by a Divisional Census Officer (D.C.O). The D.C.O. with the assistance of field staff had overall responsibility for implementing the census field programme in his\/her jurisdiction as laid down by the Census Commissioner in Banjul.\n\nA population census is defined as the total process of collecting, compiling, evaluating, analysing and publishing or otherwise disseminating demographic, economic and social data pertaining, at a specified time, to all persons in a country or in a well-delimited part of the country. A housing census is the total process of collecting, compiling, evaluating, analysing and publishing or otherwise disseminating statistical data pertaining at a specified time, to all living quarters and occupants thereof in a country or in a well-delimited part of a country. The 1993 Population and Housing Census of The Gambia was in accordance with these definitions. Further, it contained all the essential features of a census, namely individual enumeration, universality within the country and simultaneity.","coll_dates":[{"start":"1993-04-15","end":"1993-04-30","cycle":""}],"nation":[{"name":"Gambia, The","abbreviation":"GMB"}],"geog_coverage":"National","analysis_unit":"- Households\n- Individuals","universe":"The census covered everybody that is usual members and visitors present on census night and also the floating population e.g out-door sleepers and transients.","data_kind":"Census\/enumeration data [cen]","notes":"The scope of the 1993 Population and Housing Census includes:\n\nFORM A - NORMAL HOUSEHOLD: demographic, social and economic data of every such person enumerated.

This questionnaire was filled in for all buildings and compounds in the country. It was canvassed by enumerator in the first round, after house number\u00ading so as to get an inventory of compounds and buildings which was a necessary pre-requisite for conducting the census.

Each enumerator was responsible for 1EA and each supervisor for 5 enumerators. The supervisors were also supervised by the District Census Officers who co-ordinated the field activities at district level. \n\nTraining of field staff:\nTraining of enumerators and supervi\u00adsors was decentralised so as to have in each training session in each Division not more than 30 to 35 trainees. This helped in training the field staff more efficiently both in theory and prac\u00adtice. Specially trained trainers drawn from the teaching faculty of The Gam\u00adbia College were deputed to assist the Divisional Census Officers in the training programmes.\n\nMethod of data collection:\nEnumeration started with the preliminary housing census schedules (Form Cs) from 10th through 13th April. During this period, compounds and building structures were numbered and particulars relating to them were collected. The population census was a de facto one with midnight of Thursday 15th April 1993 as its reference moment. Special arrangements were made to cover institution and vagrant population as at that time. This was started just before midnight with the help of the Tactical Support Group (TSG) who provided security along the beaches and other areas suspected to be dangerous. \n\nFew respondents refused to be interviewed. Duration of interview is three weeks and we had few call backs.","act_min":"Each enumerator was responsible for 1EA and each supervisor for 5 enumerators. They were supervised based on the census methodology. GPC 6 was a form filled by Supervisors for spot checks in the compounds, to checked the level of good enumeration. The supervisors were also supervised by the District Census Officers who co-ordinated the field activities at district level.","cleaning_operations":"Editing, Coding and Verification:\nThe editing and coding manuals were prepared by the GBOS staff and trained the coders and the editors to assign a numeric codes to the questionnaires entries from the field and also to do consistancy check.\n\nData Entry, Cleaning and Processing:\nThe data was keyed into the computers by the able Data Entry Clerks using IMPS (Intergrated Microcomputer Processing System) software. Data Cleaning started during Data Entry (verification of 100 percent) structure checks, range checks and the validation on variables. Logic control and concor edit checks.","method_notes":"The Department of Gambia Bureau of Statistics adopted a model with 28 data-entry operators working in two shifts six days a week, one shift from 8 am to 3 pm and one shift from 3 pm to 10 pm. Totally 51 million keystrokes had to be entered in data-entry (see calculation in appendix). With each data-entry operator keying an average of 3,000 keystrokes per hour, working six hours per day six days a week, it would be possible to enter the 51 million keystrokes in 101 workingdays, corresponding to 5 months. The estimated number of keystrokes per hour (3000) was a conservative estimate and during the phase of data-entry the average number of keystrokes per hour reached as high as 5-6000 keystrokes per hour which was acceptable the number of keying errors taken into consideration. In order to ensure the quality of data, almost half of all data on Form A\/B (average of 49 %) was verified (rekeyed) on the computers. Rekeying of data from a specific enumeration area was done by a different operator than the one who did the actually dataentry. \n\nThe process of data-entry was supervised by a programmer as supervisor and was closely monitored by the Head off the Data Processing Section and the Data Processing Advisor. The second data-entry shift (evening shift) was beside the supervisor monitored by a Senior Staff Member of the Demographic Section. Each of the shifts was allocated a technician in case of any technical problems or breakdowns. The technicians also assisted in the distribution of EA-folders among the data-entry clerks.\n\nA special register was invented to keep track of data-entry and verification (rekeying). When an EA folder was assigned to a data-entry operator, data regarding EA number, date of issue, operator-id, terminal number and number of batches (towns\/villages within one EA) was recorded and at finalization of the EA, the date was reported again. A number of EA's were picked out at random for verification purpose (rekeying) and the error rates were monitored so data-entry operators with remarkable high error rates could be traced and steps taken to lower the error rate were introduced. As soon as data-entry of one Local Government Area (LGA) was finalized, preliminary tables showing population figures by each LGA and by each Village were produced in order to check the completeness of the datafile."}},"data_access":{"dataset_use":{"conf_dec":[{"txt":"- Sort approval from Government and GBOS before disseminating the Data. \n- The Data shall not be used for any other purpose than the above specified request. \n- All cost involved in making the Data available shall be the responsibility of the requester.","required":"yes","form_no":"","uri":""}],"contact":[{"name":"Gambia Bureau of Statistics","affiliation":"Department of State for Finance and Economic  affairs","email":"gamcens@qanet.gm","uri":"www.csd.gm"}],"conditions":"This Data should not be given for commercial conditions only for research purposes.","disclaimer":"The Gambia Bureau of Statistics (GBOS) provides the Data to external users without any responsibility implied.
