Introduction

In order to support three major censuses conducted by 4-th Department of Directorate General of Budget, Accounting and Statistics(DGBAS): ”Population and Housing Census”, ”Agricultural, Forestry, Fishery and Husbandry Census” and “Industry, Commerce and Service Census”, Information Management Center(the Center) developed various data processing systems running on mainframe. The Center also developed a PC-based Census Administration System (CAS) to facilitate the administrative operations between DGBAS and local census offices at different levels. Furthermore, in response to the changes of census environment and rapid developments in network technologies, the Center has proceeded to take advantage of registered information in governmental databases to supplement census results and developed an Online Survey System, by which DGBAS reduced required manpower and improved the efficiency for conducting census.

 

System Functions

Census Systems is composed of various systems running on mainframe and PCs. These systems include CAS used by census offices, Online Survey System used by respondents and many systems running on mainframe used in data processing phase. Main functions of these systems are listed as follows:

 

CAS

User: Personnel of census offices at different levels

Operating Environment: Windows 2000/XP (Stand-Alone)

System Function: Integrate administrative operations of three major censuses which include preceding activities, manpower allocation, expenditure payments and performance appraisal…etc.

 

Online Survey System

User: Respondents of census or survey

Operating Environment: Windows 2000/XP (Stand-Alone)

System Function: Enable respondents to fill out questionnaires online. Provide respondents the flexibility to fill out questionnaires at their own convenience. Provide them multiple channels to answer questionnaires, and then reduce their resistance.

 

PC-based Correction System

User: Data administrators or processors of DGBAS

Operating Environment: Windows 2000/XP (Client/Server)

System Function: Provide data correction function designed with graphic user interface (GUI). Display a whole questionnaire on screen at one time to facilitate the correction operation. Provide supervisors with workload management function to allocate, monitor and adjust the workload of census enumerators.

 

Data Check, Correction and Reporting System

User: Data processors of DGBAS

Operating Environment: IBM Mainframe

System Function: Provide data check, correction and reporting functions for censuses.

 

Use of Registered Information in Governmental Databases

User: Data processors of DGBAS

Operating Environment: IBM Mainframe, UNIX Servers

System Function: Integrate the registered information in governmental databases with census results. Involved activities include heterogeneous data integration, address data processing and transformation between several Chinese characters encodings.

 

 

Operating Environment

In order to fulfill different operation requirements, Census Systems use platforms and technologies which includes mainframe, PC and networks. Mainframe is used in massive data processing. PC which features in its agility is used in complex activities. Finally, Online Survey System is used in data collection as an additional channel for respondents. Adoption of all these technologies makes the censuses go on wheels.

 

Benefits

Census Systems support operations of DGBAS and census offices at different levels when censuses are conducted, and improve the flexibility and efficiency of these operations. The benefits of Census Systems are as follows: 

1.      CAS can reduce the amount of paperwork involved, support the employment and management of census enumerators, allocate workload and responsibilities, speed up the process of expenditure verification and clearance, and help to make performance appraisals. Consequently, CAS can facilitate the administrative operations between DGBAS and local census offices at different levels.

2.      Tabulation Balance System  on mainframe, PC-based correction system can provide user-friendly interfaces, decrease the use of paper, and reduce the expense and errors caused by typing. As a result, data check and correction process can be accomplished in a more limited period of time, and the accuracy of data can be largely improved.

3.      Taking advantage of registered information in governmental databases to supplement the census results can reduce the cost for conducting census and ease the burden of respondents.

 

Vision

With the advances in information technology and various innovations pushed by government, computerization of census affairs will still be on going continuously. In order to prepare for possible environment changes in the near future, the Center not only pays close attention to the trend of international census practices, but also investigates on how to apply new technologies effectively in census affairs. The goal is to provide a more efficient operating environment for census conducting.
