| Unit definitions | |
| Dwellings | A building is generally a single structure on the ground. It is covered by a roof and usually enclosed within external walls or with common dividing walls with adjacent buildings. In some areas the very nature of construction of houses is such that there may not be any wall. For example a conical roof almost touches the ground and an entrance is also provided and there will not be any wall as such. Such structures should be treated as buildings. |
| Households | A household is a group of persons who commonly live together and would take their meals from a common kitchen unless the exigencies of work prevented any of them from doing so. |
| Collective dwellings | An institutional household is a household of unrelated persons like boarding houses, messes, hostels, residential hotels, rescues homes, jails, pagodas etc. It should be noted that if a group of persons who are unrelated to each other live in a building/structure, but do not have their meals from a common kitchen, then they would not constitute an Institutional household. |
| Special populations | Persons living in boats which are on the move are referred to as boat population. Transient population includes the following: (i) persons who stayed on Census Night in airports, railway stations, bus stands, harbours, ferries and in carts (as travellers) (ii) nomadic population who camped on Census Night in a village (iii) persons who on Census Night stayed in ships within the Cambodian territorial waters and (iv) persons who stayed on Census Night at international border posts. |
| Census/survey characteristics | |
| Type | Intercensal survey |
| Title | Cambodia Inter-Censal Population Survey, 2004 |
| Statistical agency | National Institute of Statistics, Ministry of Planning |
| Population universe | All population and housing for all regular households in Cambodia excluding special settlements and institutional households |
| De jure or de facto | De facto and de jure |
| Census/survey day | March 3, 2004 |
| Field work period | March 3 to 6, 2004 |
| Questionnaire | Form A: House list and Form B: Household Questionnaire |
| Type of fieldwork | Direct enumeration |
| Microdata sample characteristics | |
| Sample design | Three-stage stratified cluster sample. The village was the primary sampling unit. Villages were stratified by Province and urban/rural status. Within each village, one census enumeration area was randomly selected. A systematic sample of 30 non-vacant households was selected as the third stage of samplling. Overall, 21,000 households from 700 of 13,886 villages were selected. |
| Sample fraction | 0.01 |
| Sample size (person records) | 102558 |
| Sample weights | Survey weights computed by statistical agency should be used for most types of analysis. |
| Units identified in microdata | |
| Dwellings | No |
| Vacant units | No |
| Households | Yes |
| Collective dwellings | No |
| Smallest geography | Districts with 20,000+ population; combined as necessary by IPUMS |
| Unit definitions | |
| Dwellings | A building is generally a single structure on the ground. It is covered by a roof and usually enclosed within external walls or with common dividing walls with adjacent buildings. Sometime a building is made up of more than one component unit which are used or likely to be used as dwellings (residences) or as establishments such as shops, business houses, offices, factories, workshops, work sheds, schools, places of entertainment and places of worship or as godowns, stores, animal sheds, etc. It is also possible that buildings which have component units may be used for a combination of purposes such as shop-cum-residence, workshop-cum-residence, office-cum- residence, etc. |
| Households | A household is a group of persons who commonly live together and would take their meals from a common kitchen unless the exigencies of work prevented any of them from doing so. There may be a household of persons related by blood or a household of unrelated persons or having a mix of both. |
| Collective dwellings | Examples of institutional households or unrelated households are boarding houses, hostels, residential hotels, rescue homes, jails, pagodas, etc. |
