1. Data processing of 2000 population and housing census of Mongolia Munkhbadar Jugder, Senior officer of Population and housing census bureau, NSC of Mongolia National Statistical Committee of Mongolia

2. BRIEF HISTORY OF POPULATION CENSUS Population censuses have a relatively short history The interest in population size has been present as long as socially organized human communities Population counts throughout history, usually associated with the demand for taxes or the need to estimate potential military strength. It is only in the past 200 years or so that periodic censuses were taken and the results factually recorded.

3. Cont` The first census in the 20 th century was conducted in 1918. Further censuses being conducted in 1935, 1944, 1956, 1963, 1969, 1979, 1989 and 2000. The latest 4 censuses were organized along with the housing census. Since Mongolia became a member of COMECON in 1962, the censuses in 1969, 1979, and 1989 followed the common principles of population census in COMECON countries.

4. Cont` The 2000 census was the first census that was organized in transition economy. In addition, 2000 census followed UN principles and guidelines in organizing population census. In 2000, the main legislative environment for the census was a provision of the Statistical Law to carry out Population census every 10 years.

5. DATA PROCESSING We have developed our application which was used for data entry in-house. Coding – manually. But computer assisted coding was used for purpose of testing in some part of questionnaire Editing – both manually and automatically Entry or typing – manually

6. The processing system National Statistical Office (NSO) was not in a position to begin the basic design of the processing system in later of 1997. However, with the assistance of UNFPA and UNSD, from the first quarter of 1998 NSO was provided with new equipment, components and software. It was thus able to establish the basis for strengthening the technical capacity required for the 2000 census. The NSO purchased a range of equipment including 38 Compaq computers, two ACER server computers and other equipment.

7. Cont` On the software side, the NSO decided to process the census using IMPS (Integrated Microcomputer Processing System) Four programmers of the NSO participated training in Japan, Kazakhstan and at the Bureau’s headquarters in Washington D.C. Apart from the use of IMPS, the NSO developed other census applications, for example, using the CLIPPER and VISUAL BASIC languages.

8. Cont` Data entry was designed for LAN using a Windows NT Server V4.0 as the control center. The center-server computer was a Pentium II, 366 Mhz, 128 MB, and 9 GB SCSI HDD and the operators’ computers were Pentium 133-166 Mhz CPU, 16MB RAM, 1.2-2.1 GB HDD. A new server was purchased from Dell and installed at the beginning of September 2000, thanks to the generous support of the Australian Government

9. Coding and data entry Most of the coding was done manually and were used CSPro 3.3 But some variables for example, classification of occupation and class. of all industrial activity was coded with assistance of computer. A special application to speed coding named SEARCH was also developed.

10. Cont` Automatically coding was very time saving and coding had finished within 44 days. For data entry, computer editing and tabulation, modules of the IMPS package were used

11. Cont` Apart from the use of IMPS, the NSO developed other census applications, for example, using the CLIPPER and VISUAL BASIC languages. Thirty-six computers (workstations) were available for data entry Two servers were operating and connected to the network.

12. Editing Editing was completed in two stages. In the first stage records were edited manually In the second they were automatically edited by using the editing module of the IMPS package, Concor

13. Issues raised Many issues were raised during the 2000 census. Attempts to tackle the problems encountered have certainly resulted in a more streamline data processing service within the NSO. The question of geographic distribution of processing also needs pursuing. Given the advances in automatic data transmission that can be expected

14. Data processing 2010 census NSC is aiming to utilize modern technology for data processing NSC is establishing GIS to utilize in enumeration and intends to use for data analyzing and dissemination GPS will be used for taking household waypoint also Data processing will be done in local networking environment NSC is planning to utilize CSPro for data entry OCR/ICR will be utilized for small percent data capturing of the questionnaire And detailed plan for data processing is under discussion
