1. Overview of survey or census
- Title of survey: Viet Nam Child Disability Survey 1998
- Date of latest data collected: June 1998 - February 1999
- Periodicity of survey: ad hoc
- Contact institution: Dr. (Mr.) Truong Van Phuc, First Deputy Director,

2. Brief summary of survey or census
- What information on disability is conducted: Prevalence and types of
child disability, the causes of child disability, the socio-demographic characteristics of
children with disabilities (CWDs), and the patterns of utilization of rehabilitation
services and the social and economic circumstances of CWDs. The patterns and norms of
government and community support for functional rehabilitation, education, vocational
training, and job opportunities for CWDs, and their level of integration in daily life in
the community were also assessed in the survey.
- The data collected are used for policy formulation, program planning
and decision making for rehabilitation services, and for the evaluation of disability
programs' impact on the lives of CWDs and their integration in community life. The
information is needed to plan training for teachers in special education, inclusive
education, and vocational training programs, and to train social workers, physical
therapists, speech therapists, orthopedic specialists, other medical and psychiatric
specialists, prosthetics and esthetics workshop technicians, and community-based
rehabilitative workers. The information is also used to determine whether the current
supply of rehabilitative devices (e.g. hearing aids, outhouses, wheelchairs, special
glasses, prosthetics, etc.) is sufficient to meet the demand for these devices.
- These users were involved in deciding what information to collect.
- The definition of CWDs applied to the survey corresponds to the
definition of disable people in the State Law on Disable Persons, which was approved in
July 1998 by the National Assembly of Viet Nam and which became effective on November 1,
"Disable children are those aged 0-17 who lack one or some body parts or functions in
various types of disability preventing action or weakening action of working, living,
3. Scope of survey or census
- The survey covers children with disabilities aged 0-17
4. Coverage and sampling
- Coverage of the survey:
Survey sample includes 1,148 CWDs living in households in 16 provinces/cities covering all
eight economic regions of the country and 230 CWDs living in eight institutions.
- Sampling frame and sampling:
In the community-based survey, a three-stage stratified random sampling procedure was used
to produce representative estimates of the prevalence of child disability for the eight
regions, for urban and rural areas and for the country.
First stage: The whole country was divided into 8 regions.
Second stage: 16 provinces/cities were randomly selected from the 8 regions: two
provinces/cities from each region. The selected provinces/cities then were divided into
rural and urban areas: rural communes and urban wards and a sample of rural communes and
urban wards were selected for each province/city.
Last stage: Clusters of households were randomly selected from the selected
communes and wards.
- Sample size:
From 16 provinces/cities 96 household clusters were selected (survey sites), including 48
rural clusters and 48 urban clusters. For urban chosen clusters, 12,480 households were
selected. For rural chosen clusters, 10,560 households were selected. This brings a total
of 23,040 households, which gives 1,148 CWDs aged 0-17.
5. Are there other data sources which you use to benchmark your survey results? (e.g.
previous surveys to compare with? what evaluations did you make of the results?)
There are no other data sources before the survey.
6. Response and non-response
7. Data collection (Attach or mail us a copy of your questionnaire)
- Face-to-face interviews were applied
- Type of respondents: CWDs. For younger children and some severely CWDs
the parents or other family members were interviewed.
8. Measurement error
- A pilot test of the questionnaires was conducted. Two-level trainings were conducted:
Training of trainers at central level and enumerators training at provinces/cities.
9. Highlights of the strengths and limitations of survey or census Strengths: (e.g. a
very detailed survey; sound sample design; use of international standard concept and
