Introduction The 2002 Post Enumeration Survey (PES) was the first of its kind to be conducted in Tanzania The 2002 Post Enumeration Survey (PES) was the first of its kind to be conducted in Tanzania Post independence censuses carried out in 1967, 1978, 1988 and Post independence censuses carried out in 1967, 1978, 1988 and Basically, the objective of the 2002 PES was to evaluate the accuracy of the 2002 Population and Housing Census. Basically, the objective of the 2002 PES was to evaluate the accuracy of the 2002 Population and Housing Census.

The PES During implementation of the PES a number of activities were undertaken, including: During implementation of the PES a number of activities were undertaken, including: Establishing PES Organization Structure Establishing PES Organization Structure Preparation of survey design, questionnaire, manuals, work-plan and budget Preparation of survey design, questionnaire, manuals, work-plan and budget Development of analytical plan including dummy tables Development of analytical plan including dummy tables

The PES Development of computer programmes for editing, data entry, tabulation and weighting of the results Development of computer programmes for editing, data entry, tabulation and weighting of the results Recruitment and training of enumerators and supervisors, data entry operators, matching and reconciliation clerks Recruitment and training of enumerators and supervisors, data entry operators, matching and reconciliation clerks Matching PES and census records Matching PES and census records Undertaking reconciliation visits to selected areas, and Undertaking reconciliation visits to selected areas, and Data processing, analysis and report writing.

The PES cont. A total of 915 out of 53,071 enumeration areas were selected using Probability Proportional to Size (PPS) A total of 915 out of 53,071 enumeration areas were selected using Probability Proportional to Size (PPS) An average of 30 EAs per region An average of 30 EAs per region Institutional population such as hospitals, schools, etc.; migratory population, homeless, on transit passengers etc. were not included in the design Institutional population such as hospitals, schools, etc.; migratory population, homeless, on transit passengers etc. were not included in the design The results of the 2002 PES indicate that the 2002 Population and Housing Census coverage rate was about 94 percent of the targeted total population The results of the 2002 PES indicate that the 2002 Population and Housing Census coverage rate was about 94 percent of the targeted total population

The PES cont. The 2002 PES overall omission rate for both sexes was 6.89 percent The 2002 PES overall omission rate for both sexes was 6.89 percent The omission rate for males was 6.90 percent, being slightly higher than that of 6.77 percent for females The omission rate for males was 6.90 percent, being slightly higher than that of 6.77 percent for females The population in age range of 10–19 years recorded a higher omission rate compared to older population groups The population in age range of 10–19 years recorded a higher omission rate compared to older population groups Moreover, rural-urban differentials revealed a higher percentage of omission in urban areas compared to rural areas. Moreover, rural-urban differentials revealed a higher percentage of omission in urban areas compared to rural areas. Rural omission rate was 6.74 while the urban rate was 6.95 Rural omission rate was 6.74 while the urban rate was 6.95 This is probably due to difficulties in enumerating urban populations, which is a common feature in African censuses.

Lessons Learnt and Recommendations Planning and preparations of the census has to include PES preparations too. Planning and preparations of the census has to include PES preparations too. The right allocation of financial resources is key element. The right allocation of financial resources is key element. Right allocation invites proper timing and allocation of adequate funds to undertake PES activities. Right allocation invites proper timing and allocation of adequate funds to undertake PES activities. Human skills development, especially in the area of post- enumeration surveys, is a necessary requirement Human skills development, especially in the area of post- enumeration surveys, is a necessary requirement The question of independence and objective evaluation is important in PES. The question of independence and objective evaluation is important in PES.

Lessons Learnt and Recommendations To limit the size of EAs to an estimate of hundred households each, to both urban and rural areas. In scattered areas fewer number of households may be considered To limit the size of EAs to an estimate of hundred households each, to both urban and rural areas. In scattered areas fewer number of households may be considered To revise the census frame from time to time and keep it as up to date as possible by improving descriptions in their boundaries, physical features and lists of heads of households. To revise the census frame from time to time and keep it as up to date as possible by improving descriptions in their boundaries, physical features and lists of heads of households. To provide enough training to enumerators on aspects of cartographic materials to carter for necessary improvements on EA maps during enumeration. To provide enough training to enumerators on aspects of cartographic materials to carter for necessary improvements on EA maps during enumeration.

Lessons Learnt and Recommendations To use household dwelling numbers in order to facilitate the matching of households in both, the census and the PES. To use household dwelling numbers in order to facilitate the matching of households in both, the census and the PES. The enumerator should write full names to make the matching process easier and faster. The enumerator should write full names to make the matching process easier and faster.

Future Plans A Post Enumeration Survey is planned to be conducted for the 2012 Population and Housing Census A Post Enumeration Survey is planned to be conducted for the 2012 Population and Housing Census To access the degree of coverage of the census and content deficiencies To access the degree of coverage of the census and content deficiencies To obtain information for the design of future censuses and surveys To obtain information for the design of future censuses and surveys
