Introduction

• 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 2002.
• Basically, the objective of the 2002 PES was to
  evaluate the accuracy of the 2002 Population and
  Housing Census.

4
The PES

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

5
The PES

• 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
• Matching PES and census records
• Undertaking reconciliation visits to selected
  areas, and
• Data processing, analysis and report writing.

6
The PES cont.

• 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
• 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

7
The PES cont.

• 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 population in age range of 1019 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.
• 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.
• The right allocation of financial resources is
  key element.
• 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
• The question of independence and objective
  evaluation is important in PES.

9
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 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.

10
Lessons Learnt and Recommendations

• 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.

11
Future Plans

• 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 obtain information for the design of future
  censuses and surveys
