Population and Housing Census [hh/popcen]
Series Information
Sri Lanka has a long history of census taking. The first scientific census was conducted in 1871. Since then censuses have been conducted once in ten years with certain exceptions. The 1971 Census of Population is particularly significant in the history of regular census taking in Sri Lanka in that it is the century year of population censuses. The census was conducted on the 9th of October 1971 and it was the 11th of the series. The previous census was conducted in 1963. The census 1971 is significant for two reasons. Firstly it was taken one hundred years after the first census. Secondly it reverts to the tradition of taking the census in the year ending in 1 which had been maintained until 1931. It is hoped that this tradition and the decennial interval could be maintained in the future.
Abstract
A Census of Population and Housing is the single most extensive statistical undertaking of a country. In order to plan and implement programmes and activities, statistics are needed by the Government administrators of various levels, private users, research organizations and the general public.
The 1971 Census was conducted under the Census Ordinance N0. 9 of 1900. (Chapter 143) According to that it shall be lawful for the Minister from time to time by order published in the Gazette, to direct that a census be taken of the population, agriculture (including animal husbandry ) trade, labour, industry or commerce or such other matters as he may deem necessary for ascertaining the social, civil or economic conditions of the inhabitants of Ceylon. The CPH 1971 has been designed to collect various information about the characteristics of the population and the households in Sri Lanka.
The CHP1971 provides
a. Reliable and detailed benchmark statistics on the size, distribution and composition of population.
b. Information pertaining to the characteristics of the housing units.
c. Information on the characteristics of the households

Data Collection Mode
Face-to-face [f2f]
Supervision
A number of Census Blocks grouped together according to contiguity and compactness formed a Census Circle, each of which was placed in charge of a Supervisor. Only persons possessing administrative capacity and of high integrity and education were chosen as Supervisors. Generally, government or local government officers of intermediate grades were so appointed. The supervisor was responsible for the supervision of the census arrangements and the work of the census enumeration within his circle.
Data Collection Notes
Training classes
Training classes were organized for the Census Supervisors and for the large number of enumerators. A few Master Trainers drawn from the permanent cadre of Statisticians and Statistical Officers of the Department were first given training on the various aspects of the Census work. These Master Trainers were then sent to the various districts to impart the necessary training to Supervisors. Each Supervisor in turn conducted a training class for the Enumerators assigned to his circle. Training classes for Supervisors were held during the period 16-31st August 1971. The training of Enumerators was carried out during the first two weeks of September 1971.
Training
The training of the Census staff was a three tiered process. In the first tier, the master trainers were trained. They were the senior officers of the DCS in the ranks from Statisticians to Deputy Directors.
The second tier was the training of the trainers by the master trainers. The trainers were the statistical officers of the DCS and who were entrusted with the task of training all supervisors and enumerators. The third tier was the training of supervisors and about 120,000 strong army of enumerators.
The census was carried out in 4 stages,
Stage-1) Mapping Operation - (From January to December 2000) GN divisions (Grama Niladhari) are the lowest administrative units in the country. To avoid omissions or duplications of building units or any individuals GN maps were drawn with clear boundaries. As the GN divisions are too large to handle in a census operation they were subdivided into smaller area units called the 'Census Block'. Around 60 housing units and /or other building units in the rural sector and around 80 housing units and/or other building units in the urban sector comprised a census block. In the mapping operation the census block maps were also marked in the GN division maps.
Stage-2) Listing Operation (February and March 2001)
Based on the maps prepared, a building unit or part of a building unit is identified and categorized as follows:
(1) Housing Unit
(2) Collective living quarter
(3) Institution
(4) Non-housing unit
All of the above categories were listed in a Pre-Listing Form (F1) during the listing operation together with additional information such as number of residents, whether there is agricultural activity or a business is going on and so forth. This list with additional information would provide the basic frame for the censuses and various surveys, which will be conducted by the Department of Census and Statistics, during the next ten years.
Stage-3) Preliminary Census (From 25th June to 5th July 2001)
In this stage, the enumerators collected information pertaining to every individual who usually live in the household using the Population and Housing Schedule. Each 'Census Block' was assigned to an enumerator. There were around 120,000 enumerators throughout the country. In addition to the population data, information on housing and household were also collected from each housing unit and collective living quarter on a 100 percent basis.
At the time of recording a persons' individual information to the 'Population and Housing Schedule (F3)', if a physically or mentally disabled person were found in the household, enumerator completed 'Schedule for Disabled Persons(F4)' for that person after completing population and housing schedule for the household.
Stage-4) The Final Census (17th July 2001, 6.00 p.m. to 12.00 mid night)
The time of census taking was adjusted in certain areas depending on the prevailing ground situation in that area. The referred date for the final census is the final date and all information relating to each individual was collected from 6.00 pm on the 17th July 2001.
The final census enumeration was carried out as a direct check on the persons enumerated in the preliminary census, in order to ensure that no person is missed or enumerated more than once. In particular a person found in any unit is classified into:
1). A usual resident and actually present
2). A usual resident but temporarily absent (excluding those who were abroad)
3). A household member but currently abroad
4). A non-usual resident but temporarily present on the census night.
If the enumerator finds a person in a household belonging to a category (4), then his/her particulars are recorded in the census schedule pertaining to that household.
Special arrangements were made to enumerate people staying outdoors on the final census night. Places like barracks/camps of forces, hospitals, large hostels etc. were covered by officers selected for the purpose from their own places.
The method of enumeration was “de facto” basis.

A few Master Trainers drawn from the permanent cadre of Statisticians and Statistical Officers of the Department were first given training on the various aspects of the Census work.

Data Collectors
Questionnaires
Questionnaires
A main area for the advance preparations for the 1971 Census was the redesigning of Population and Housing schedules in order to minimize the time required for coding the data. One of the reasons for the delay in tabulation of information from the earlier censuses particularly the 1953 and 1963 censuses was the inordinately long time taken at the Head Office to code the information before punching the information on cards. With a view to avoiding such delays it was decided to have as much of the coding as possible done in the field itself by the enumerators. Topics such as Sex, Marital Status, Religion, Ethnic Group etc; which consist of a few well defined categories could be easily entered on the schedules in the form of codes. A schedule designed for the purpose of was tested at the first Pilot Census. In this schedule, however, the codes for each category were shown at the bottom of the schedule and hence the enumerator had to frequently shift his eyes up and down between the cage in which the entry was to be made and the section at the bottom of the schedule showing the codes. This proved to be the somewhat strenuous and time consuming. Some of the codes were easily remembered by the enumerator e.g. Male 1, Female 2. But in the case of other items like Ethnic Group & Marital Status which contain more than 4 or 5 categories, the possibility of some mixing up of codes existed, leading to inaccuracy. On the basis of experience of the first Pilot Census, the schedule was redesigned and the codes were shown against the question in respect of which answers were sought from the respondents and the enumerators required to indicate the answers by circling the appropriate code. This layout of the schedule eliminated errors resulting from marking of a wrong code which was possible in the case of schedules used at the first Pilot Census.
A similar procedure, however, could not be adopted in respect of such topic as educational attainment, occupation and industry, in respect of which the number of possible entries were quite large. In these cases the enumerator wrote down the answers and the coding was done later, in the office, by specially trained coding staff. The Housing schedule was also designed on the same basis.
The schedule which contained the item in respect of which information was collected from all persons in the country was called the Population Schedule (General) and was printed on white paper to distinguish it from the Population Schedule (Special) printed on pink paper. The Population Schedule (Special) contained in addition to those on the Population Schedule (General) items which were to be collected from a sample only. The Housing Schedule was printed on blue paper.

Data Processing
Data Editing
The Census Schedules, on receipt in the Head Office, were checked for any possible shortages and then edited and coded where necessary by specially trained staff, prior to being passed on to the Data Processing Division, for punching and tabulation.
Computer Editing
Before the punched cards were transferred to the computer room for processing, certain manual checks for control figures and sight checks were carried out administrative regions. A comprehensive editing procedure was done on the computer. The computer program which checked the records comprised of five basic edits.
They were :
1. Checking to ensure that all data was numeric
2. Checking the validity of numerical codes entered for descriptive data
3. Checking the range of codes
4. Checking the consistency of related data
5. Checking and imputation of a limited amount of data for omissions.
Editing to ensure that all data was numeric enabled the detection of errors occurring due to punching and verifying machine faults. All the other edits provided a complete check for validity and consistency of the records. Only records which satisfied all edit checks were written on tape while the error records were appropriately printed by districts. These error lists were referred to the appropriate division for correction. The corrected records were re-punched and passed through the edit program again. This procedure was adopted for each district until no errors were printed. At the commencement of processing 4 error lists for each district were referred back, but with experience gained in the correction of error lists, the reference was cut down to two lists

Other Processing
It was in respect of the 1971 Population Census that an electronic computer was used for the first time in Sri Lanka to process census data. As IBM System/360 Model 25 installed in 1970 was inadequate, the system was enlarged in 1972 to cope with the voluminous work involved.
Data Preparation
Work on punching and verifying commenced in August 1972. Twenty IBM 024 punchers and nineteen IBM 056 verifiers were used for punching and verifying over 12 million cards. Verifying was done on a quality control basis and averaged about 10 percent to 25 percent of the records. For 17 months machines were used on a double shift. The data preparation work took approximately 21 months.
Computer Processing
The basic approach of the systems design was to create sub master files for groups of tables containing variables that were required only that particular set of tables. This enable the creation of short records with subsequent advantages in processing. Processing was done at district level except for four tables where aggregations were done at D.R.O. and G.S. Division levels. The processing programs created aggregated records for each table which were updated as each district was processed. On completion of the last district the aggregated records for each table gave the all island figures which were formatted and printed. Thus the programming was in four stages.
a. Programs which created sub-masters
b. Programs which processed the data by districts and created summaries by districts.
c. Programs which processed the district summaries to create the all island summaries
d. Programs which printed out the summary figures.
In all 76 programs were written in Assembly and Report Program Generator Languages. At the beginning all programs were written in Report Program Generator Language so that the programs could be written in a short period of time. The processing time of such programs, however, was found to be too long. Hence, as the work progressed, the programs were written in Assembly Language to minimize the processing time. The processing of all data from enumerators' abstracts, ten percent sample schedules and hundred percent general schedules, was completed in approximately twenty months.
