Series Information
Information on disabilities ie. whether a person was blind, deaf and deaf-mute or crippled has been obtained all the censuses in Sri Lanka from 1871 with the exception of the censuses in 1931 and 1971.
At the Census of Population and Housing 2001, the information about physical and internal disabilities were collected through a special schedule. Such data were confined only to physical disabilities in previous censuses conducted in 1946, 1963 and 1981.

Abstract
The information about both physical and mental disabilities were collected in the Census of Population and Housing 2001 using a special schedule. Disabled persons were identified during the preliminary census through the 'Population and Housing Schedule (F3)'. Simultaneously the specially designed 'Schedule for Disabled Persons (F4)' was used to collect the information about the type of disability, age at which the disability occurred and cause of disability.
Disability information was not collected from persons present in non housing units and from homeless persons at the final Census day of the Census of Population and Housing 2001.

Coverage
Geographic Coverage
National Coverage
The enumeration of disabled persons was conducted as an activity parallel to the enumeration of the Census of Population and Housing 2001. The census enumeration was able to be carried out completely in 18 out of 25 Districts. Due to the disturbed conditions in Northern and Eastern provinces certain areas could not be enumerated completely.
Note : Disability information was not collected from persons who are homeless, at the final Census of the Population and Housing 2001.

Sampling
Response Rate
One general opinion of the enumerators was that the method adopted [face to face] for enumeration found to be somewhat embarrassing to some householders to provide disability information pertaining to their family members.
Note - This is an un-quantified opinion but could be considered to seek improved alternatives in enumerating future disability surveys.

Supervision
The role of the supervisor was to coordinate the activity of data collection in the Census Blocks, supervising the quality of the collected data and managing the interviewers and accessories.
Data Collection Notes
At the stage of preliminary census, the enumerators collected information pertaining to every individual who usually live in the household using the 'Population and Housing Schedule (F3)'. Each 'Census Block' was assigned to an enumerator and there were around 110,000 enumerators throughout the country. At the time of recording a persons' individual information to the Population and Housing Schedule, if a physically or mentally disabled person were found in the household, enumerators completed the questionnaire of Schedule for Disabled Person (F4) for that person after completing population and housing schedule for that household.

Data Processing
Data Editing
Data processing consisted of two major phases.
(1) Manual editing and coding,
(2) Computer processing such as fixes while data entry, structure checking and completeness and secondary editing..
Manual editing was confined in the field to simple checks such as verification of area identification codes. Coding was required only in respect of three questions, namely educational attainment, place if trained for any vocation as a disabled person and occupation.
Data were entered for the second time to verify the original keyed data which is called the verification process. When the administrators fell that the overall error rate is diminishing, the verification process was mitigated step by step assuming that the operators are progressively improving in entering the questionnaires correctly.
A series of computer edit checks were carried out and records containing errors were printed for visual verification. These edit checks included both range and consistency checks.
Processing was done on IBM S390 integrated server 3006 model B01 and several personal computers.
Keyboard to disk type data entry was adopted for data capture.
The software Integrated Micro Computer Processing System (IMPS) developed by U.S. Bureau of Census was used to data processing activities including data entry

Other Processing
1) Merge edited batch-wise data to form the Master for each district.
2) Imputations
3) Recoding of variables needed for analysis
4) District-wise tabulations
5) The 18 complete District data batches were finally merged and produced the full file.
All tabulations were done by the application of SPSS software package.
