| What is Redatam? |
Redatam is an acronym for REtrieval of DATa for small Areas by Microcomputer. Redatam+SP (abbreviated R+SP) is the last version of the fourth generation of the software. It can be used in Spanish, English or Portuguese, with Microsoft Windows 95, 98, NT4 or 2000, in any IBM compatible microcomputer (winR+ v1.2, the previous generation of the software, also works with Windows 3.1).
The program uses a compressed hierarchical database, which can be created in R+G4, and which can contain microdata and/or aggregated information with millions of records for persons, houses, city clocks or any geographical division of a country. These data can come from any combination of census, survey or other sources. A database can be processed in association with external databases in common formats such as dBase. Very large non-geographical hierarchical databases have also been created in such fields as International Trade.
The user can define any area of interest in a database (such as city blocks) or any combination of areas, create new variables, obtain various types of tabulations extremely rapidly, export outputs to other software and graphically display results. The data at different geographical levels can be combined hierachically to create aggregated variables and the results shown on maps in R+G4 or transferred to a Geographical Information System (GIS).
Versions of Redatam are used in the majority of the Latin American and Caribbean countries, in many of Africa and Asia, as well as in many developed countries; around 1600 users and institutions have been registered in about 80 countries. The first generation of Redatam for DOS was released officialy in 1987. All generations of Redatam have been developed and maintained by the Latin American and Caribbean Demographic Centre (CELADE), which is the Population Division of ECLAC.
The development of Redatam+SP and other members of the REDATAM family received financial support from IDRC, CIDA, UNFPA, IDB and the regular budget of the United Nations.
