Population universe The 1970 Population Census was de facto count of all persons in the country on the midnight of August 24/25, 1970. However, the manner in which certain categories of persons were enumerated varied.

Nomads - In Malaysia, nomads are to be found amongst the Orang Asli. (Aborigines). The Department of Orang Asli assisted in enumerating the Orang Asli.

Persons living in remote areas
– The problem of persons living in remote and inaccessible areas was a particular problem in Sabah and Sarawak. In these areas, the two-stage system of enumeration was not employed, and the count was undertaken as a single operation.

Resident merchant, seamen and fishermen at sea on Census Night – In the Census these persons were designated as persons afloat. They were categorised into the following groups and with the exception of the last group (e), they were included in the Census Count:

(a) Crew and passengers on coastal ships sailing in Malaysian waters or at Malaysian ports or sailing between two Malaysian ports,
(b) Crew and passengers on vessels registered in Malaysia and engaged in regional trade,
(c) Persons living on boats and vessels moored in harbours, rivers or creeks,
(d) Fishermen at sea on Census Night, and
(e) Crew and passengers on foreign registered ships in port or in Malaysian waters.

Civilian residents who cross a frontier daily to work in another country – This category of persons was included in the Census in conformity with the principle of counting all persons present in the country on the night of August 24/25, 1970.

Civilian aliens who were temporarily in the country as seasonal workers were included in the Census count. So were all other Civilian aliens, other than those already listed, working in the country. Also, civilian aliens, other than those already listed, temporarily in the country were included in the count.

Foreign military, naval and diplomatic personnel and their families located in the country – All persons in this category were included in the Census count with the exception of persons claiming diplomatic immunity.

Wayfarers, homeless people and persons in hotels were included in the Census count – Special arrangements were made with the police and railway authorities to enumerate these persons. Recourse was made to road blocks to count travellers.

Military, naval and diplomatic personnel and their families located outside Malaysia were excluded from the Census count. Given the de facto approach, which requires only a count of persons present within Malaysia, these categories of persons were excluded from the count. Similarly, civilians who were temporarily away from the country on the night of the Census, were excluded.

Civilian residents, other than those already listed, working in another country were also excluded from the count. So were civilian residents, other than those already listed, temporarily absent from the country.

Civilian aliens who cross a frontier daily to work in Malaysia were omitted from the count.
The 1980 Population Census included all Malaysians and non- Malaysians who had slept in private or small institutional living quarters during Census Night. However, there were several group of people who did not fall into the above category and for whom special arrangements were made:

(a) Persons living in remote and security areas
- These include the Orang Asli (Aborigines) in Peninsular Malaysia and other indigenous groups who live deep in the jungles in the interior of Sabah and Sarawak; also persons in security areas were included. The enumeration of such persons was done in a single stage operation.

(b) Military, naval and diplomatic personnel and their families and civilians staying outside Malaysia
- Since the strategy of enumeration was based on the de facto approach, this group of persons were excluded from the count. Civilians who were temporarily away from the country were also excluded.

(c) Resident merchants, seamen and passengers who were at sea on Census night

The following were included:-
(i) Crews and passengers on coastal ships sailing in Malaysian waters or in Malaysian ports or sailing between Malaysian ports;
(ii) Crews and passengers on vessels registered in Malaysia and engaged in regional trade. Crews and passengers on foreign registered ships in port or in Malaysian waters were, however, excluded.

(d) Civilian residents who cross a frontier daily to work in another country
-This group was included in the census if they were in Malaysia on Census night.

(e) Foreign military, naval and diplomatic personnel and their families located in the country
-All persons in this category were included in the census with the exception of persons having diplomatic immunity.

(f) Transients
-Wayfarers, homeless people and travellers were included in the census. Special arrangements were made with the police, railway and marine authorities to enumerate these people.

(g) Institutions
-Institutions in large hotels, hostels, hospitals and prisons were also included.

(h) Army camps and army personnel on patrol
-Army personnel were included in the census, through the assistance of the commanding officers of the camps.
In the 1991 Population and Housing Census, all persons including foreigners who were in Malaysia on Census Day were enumerated. Generally, the majority of people were found in their respective homes on August 14, 1991 and were enumerated under the normal enumeration procedures. However, a minority of the population did not fall in the above category and for the persons, special enumeration arrangements were made. The groups referred to were:

Field work period The 1970 Census was conducted as a two-stage operation comprised a house numbering stage and an enumeration stage. The first stage enumeration was carried out from July 27 to August 9, 1970. The second stage was carried out from August 25 to September 7, 1970. The 1980 Population and Housing Census was conducted in two stages. The first stage involved the listing of all living quarters as well as a preliminary count of the population and was carried out from May 17 to 26, 1980. The second stage involved the actual count of the population as well as an enumeration of the personal characteristics of every person, and was carried out from June 11 to 28, 1980. The 1991 Census has successfully attempted the one-stage operation of simultaneously listing the living quarters and interviewing the occupants to obtain information relating to households and persons using a consolidated questionnaire. A consolidated housing, household and person form was designed for this purpose. The enumeration period for the 1991 Census began on August 14, 1991 and continued until August 30. In the 2000 Census, the listing of living quarters and interviewing of respondents to obtain information relating to households and persons were done simultaneously in a single stage operation. The enumeration was conducted from July 5 to 20, 2000.
Enumeration forms Five separate forms constitute the total questionnaire. There was a House Listing Book, a Living Quarters Form, an Agricultural Census Form, a Household Census Form and a Persons Form. For ease of reference those were designated as Forms 1, 2, 3, 4, and 5 respectively. Five types of schedules were used for the 1980 Population and Housing Census: Form 1 consisted of a House Listing Book; Form 2 was the schedule used in the Housing Census; Form 3 was used to collect information on households and; Form 4 was used for collecting individual particulars. However, persons in large hotels, hostels, hospitals, prisons and other institutions were enumerated on Form 33, a shortened version of Form 4. Four types of forms were used in the 1991 Census.

Document 1: Listing Book which identified the Enumeration Block and list all living quarters in each block.

Document 2: The main census form which required the filling in of particulars on all listed living quarters, household and person.

Document 2a: Person Form. This document was used if a household contained more than seven members.

Document 3: Self-enumeration Form for Living Quarters/ Household.

Document 3a: Self-enumeration Person Form.

Document 4: Listing Card which assigned a control number to the living quarters.
In the 2000 Population and Housing Census, three main schedules were used namely, Documents 1, 2 and 3/3a. Document 1, which is the Listing Book, was used to list all living quarters and obtain some related information. Document 2, which represented the main questionnaire, was divided into three sections. It collected information on living quarters, households and persons. Document 3/3a, which was an abbreviated version of Document 2, was used for institutions.
