Title 1970 Population and Housing Census
Statistical agency Department of Statistics Malaysia
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.

Unit definitions
Dwellings Living quarters have been defined for census purposes as places of abode, which are structurally separate and independent. The terms separate and independent mean the following:

Separate: A structure is considered separate if it is surrounded by walls, fence, etc., and is covered by roof.

Independent: A structure is said to be independent if it has direct access via a public staircase, communal passageway or landing (that is, occupants can come in or go out of their living quarters without passing through someone else’s premises).

In general, living quarters can be classified into two categories, that is:

(i) Built or converted for living (e.g. house, flat, apartment, shophouse, makeshift hut, hotel, hostels, etc.)
(ii) Not meant for living but used for this purpose on Census Day (e.g. in a building such as office, shop, barn, community hall, etc.)

Living quarters built or converted for living can be further classified into housing units and collective living quarters. Housing units are classified into six main types, namely: House; Flat/apartment/condominium; Shop house, office; Room (with direct access to the outside); improvised/temporary hut; and others. House can be further classified into Detached house; and Semi-detached house.

Households A household consists of a group of persons who live together and make common provision for food and other essentials of living. The group pay for main meals out of a commond budget and have common arrangements for basic needs.

A household may either be a one person household or a multi-person household. The persons may be related by blood or marriage, or unrelated, or a combination of both.

Collective dwellings Living quarters which is built or converted for living (e.g. house, flat, apartment, shophouse, makeshift hut, hotel, hostels, etc.).
