Oman was the first country to use PDAs for Population Census in 2003.

In its continued efforts to ensure total quality, acquiring and adapting modern technology for census application with the view of improving quality and reducing cost and time required, engendering knowledge, and contributing to global knowledge base, the Sultanate of Oman was the First to use the  handheld computer otherwise known as the Personal Digital Assistant (PDA) for data collection in 2003 census in Muscat Governorate, and the ensuing household surveys.

The PDA makes it possible to load Satellite Digital maps, consistency rules and coding system directly into the PDA. Data required for buildings, housing, establishments, households and individuals are keyed directly into the PDA, coded and checked automatically for internal consistency, thus nullifying the need for the traditional manual data checking, editing, coding and keying. Consequently,  shortening the time required for presenting the results and reducing the cost.
