| Field work period | Population in urban areas was enumerated on census day, during which the population was "immobilized." Enumeration in rural areas continued for one month. The operation began four months earlier in National Territories and ended on census day. Unusually heavy rains caused the enumeration to be extended in some remote areas. |

| Title | XV National Population and IV Housing Census |

In the National Territories (intendances and commissaries) fieldwork continued from October through March and, for some remote areas, fieldwork was timed to avoid the rainy season. |
| Questionnaire | 5 enumeration forms applied to 5 different target populations: (f1) short form for private dwellings (90%) of the population, requested information on age, sex, and relationship to householder; (f2) long form for private dwellings (10%); (f3) group quarters, 0.17% of dwellings; (f4) indigenous private dwellings (100%), representing 0.95% of dwellings; and (f5) indigenous group-quarters, 0.01% of dwellings. |

| Statistical agency | Departmento Administrativo Nacional de Estadística (DANE) |

| Census/survey day | The collection period for the information was between May 2005 and February 2006, with interruptions for vacation periods between June and July 2005 and between December 2005 and January 2006. |
| Field work period | The work of information collection was done based on the conglomerates of municipalities formed according to their demographic dynamics, with partial immobilization. |
| Questionnaire | Three enumeration questionnaires were used:
1. Questionnaire for the Urban environment. This is carried out by the field supervisor, through observation at the block level. It seeks to provide and overview of the predominant urban setting, based on criteria of habitat which are fundamentally physical. 2. Questionnaire of Census Units. This is carried out by the enumerator starting with the information reported directly by the units. It is divided into sections for: dwellings, households, persons, economic units and agricultural units. 3. Questionnaire for Special Housing Units (LEA). In the case of military barracks and penitentiary centers, this is carried out by resident personnel, trained for this purpose by the municipal coordinator. In the remaining cases, it is the responsibility of the enumerator. |

| Microdata sample characteristics | |
| Sample design | Systematic sample of every other private dwelling. Drawn by the IPUMS from 20% microdata of private dwellings.
