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.
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
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
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 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 10–19 years
recorded a higher omission rate compared to
older population groups

Moreover, rural-urban differentials revealed a

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 postenumeration surveys, is a necessary requirement

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 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.
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.
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
