2008 Tanzania Disability Survey (TDS) Key Results

Next Step for 2008 TDS

Key achievement since last GBS Review
2
Major Objectives

The major objective of the survey was to determine
the prevalence of disability (measured as difficulties)
in the country.

The survey also intended to determine living
conditions among people with activity limitations.
3
Sample Designing



The survey covered the whole of the United Republic
of Tanzania
Information was collected from all selected households
and individuals with and without disability (measured as
activity limitations).
The survey utilized a three-stage systematic stratified
random sampling design involving clusters (EAs),
households and individual household members.
4
Questionnaires

Three types of questionnaires:



Household questionnaire: Collected basic socio-economic
conditions of usual household members and visitors. The
questionnaire also included six screening questions were used
to determine persons with disabilities
Adult questionnaire: Collected information from all person
aged 15 years and above who were identified in the
household questionnaire as having some form of disability
Child Questionnaire: Collected information from all children
identified as having disabilities.
5
Definition of Disability - USED

Definition was based on Convention 61/106 of the
United Nations on the Rights of Persons with
Disabilities. According to the convention, “persons
with disabilities include those who have long-term
physical, mental, intellectual or sensory impairments
which in interaction with various barriers may hinder
their full and effective participation in society on an
equal basis with others”.
 People are more willing to report having a ‘difficulty’
than having a ‘disability’
6
Coverage

A total of 7025 were selected for interviews

About 6882 households responded

Overall response rate was 98 percent

Key Results
Demographic Indicators




The average number of household members ranges
from 5.0 in Mainland and 5.8 in Zanzibar.
The overall average household size in Tanzania was 5.0
persons per household
These findings are consistent with findings from other
household based survey and from 2002 population and
housing census
Household headship is dominated by male regardless of
the disability status
8
Key Results – Literacy Levels

About a quarter (27.4 percent) of Tanzania’s population
aged 15 years was illiterate, with 2 in every 10 males
being illiterate compared to 4 in every 10 for women.

Illiteracy was highest among persons with disabilities.
About half of them (47.6 percent) were illiterate
compared to 25.3 percent of the persons without
disabilities.
9
Key Results – School Attendance



About one quarter of the population was reported to
have ‘no education’, about six in every ten of the
population were attending primary education and seven
had secondary education.
The proportion of females with no education at 28.7
percent was higher than that of male (20.9 percent).
People with disabilities have nearly double the
proportion of people without any education compared
to non-disabled people: 41.7 percent compared to 23.5
percent
10
Prevalence of Disability



7.8 percent of the population had some form of activity
limitation.
Disability prevalence is higher on the Mainland (7.8
percent) compared to Zanzibar (5.9 percent) and is
higher in rural areas (8.3 percent) than in urban areas
(6.3 percent).
Mainland households are more likely to have household
members with disability (13.3 percent) than Zanzibar
(9.3 percent). The overall percentage of households
with at least one member with disability was 13.2.
11
Prevalence of Disability – Age
Differentials



The prevalence of disability rises with age with a sharp increase
for persons aged 45 years and above
46 % of the population aged 80 years and above had activity
limitation compared to only 3 % for those below ten years of age
Low prevalence of disability among the population below 10
years may also be associated with the problem of identification as
it is not very easy to identify disability status among young
children. This requires further investigation within Tanzania as
well as internationally.

Prevalence of Disability – Regional
Differentials


The results show that the prevalence of disability ranges
from 2.7 percent in Manyara to 13.2 percent in Mara
region.
Higher disability rate in Mara region could be due to
tribal conflict and cultural norms and attitude prevailing
in this region, although the survey did not go further to
ask the reasons. Further study that include qualitative
approach is needed in this area.

Some Experiences of People with
Disabilities




Around a fifth of all people with disabilities reported
problems with the access to transport;
17.5 percent of all people with disabilities in Tanzania
reported having problems with availability of
information in accessible format;
10 percent of all people with disabilities reported
problems with attitudes of others at home;
33 % of all people with disabilities reported having
problems with the attitudes of others at work or school.

included in future household based surveys. The
module will also be included in the 2012 Population
and Housing Census.
