Census in Indonesia ü Population census: Ø in the years ending with 0. Ø previous population census: in 1961, 1971, 1980, 1990, 2000. Ø The next Population Census would be in 2010 ü Agricultural census: Ø in the years ending with 3. Ø previous agricultural census: in 1983, 1993, 2003. ü Economic census: Ø in the years ending with 6. Ø previous economic census: in 1986, 1996, 2006.
Data Processing Support for Population Census 1980, 1990 • Using Mainframe: • (NEC ACOS 500 in 1980) • (NEC ACOS 1520 in 1990) • Batch Processing (not interactive)
1. Data Processing Policy Decentralized & Distributed Data Processing: • Encourage End-users Computing: subject matter units are entitled to process their own survey under coordination of (after elimination of Mainframe) data processing division. • Develop application in-house by HQ & decentralize operation to Regional offices. • Implement Distributed / Client-Server Data Processing Model. 2. IT Department (Directorate of SIS) focuses on IT infrastructures & complex DP Systems such as Censuses. 8
Data Processing Support for Population Census 2000 • PC based Client-Server Data Processing • Using Scanner: Kodak DS 3500 • Speed: 3500 forms / hour • Use of OMR, ICR: Nestor Reader • ICR Ascent-Capture: started in 2003 (Census of Agriculture).
PC 2000 Data Capture Stages Ø Scan documents (produce image file) Ø Recognize image (produce ascii characters) Ø Verification & Correction (operators decide characters ambiguous to recognize engine) Ø Completion completeness check Ø Release save into database
Experience from PC 2000 • Unexpected low quality of enumerator’s handwriting to recognize by ICR • Unable to recognize characters correctly – Rejected too many values (too high confidence level) – Accepted incorrect values (too low confidence level) realized from tabulation output – Should check-digit help to increase accuracy ? • Ineffective learning engine • In a LAN environment using MS-SQl Server, 4 concurrent scanning processes slow down the whole DP activities consisting of 3 recognize stations, 10 correction stations, and 25 computer editing stations.
Experience from PC 2000 • Extra work to erase & rewrite Census Form • Powder from rubber eraser stick on Census forms & affected Scanner performance • Costly maintenance effort of Scanners which spread over all provinces • Relatively high cost (investment) for Data Capture H/W& S/W • However, Data Capture using scanner was able to shorten Data Processing Completion Time. • It was not easy to find out well motivated enumerators & Data Capture operators.
PC 2010 Data Processing Plan Main Documents: • Short Form for Listing & basis for 10% sample, using data entry (DE), : C • Long Form : L using scanner, complete enumeration (100%) of households & members : S using data entry / scanner, 10% sample. Estimation: • • No of Districts / Regency = 456 No of Sub-districts = 5, 901 No of villages = 72, 084 No of Census Blocks = 658, 308 (in year 2000) No of smallest Administrative Areas (SLS) = 900, 000 No of households = 64 million No of population = 236 million
Document: Batch Control
PC 2010 Data Processing Plan (cont) Issues on existing Scanners: Ø Kodak DS 3500 procured for PC 2000: 79 units Ø About 60 % of them need spare-parts replacement Ø Spare-parts are discontinued. (Dicom Singapore eager to reserve all available spare-parts to BPS) Ø Running out of Ascent Capture Counter (dongle) limit Ø Operable uncertainty for PC 2010
1. Utilize scanners with character recognition PC 2010 Data Processing Strategy technology (OMR, OCR, ICR), focused on OMR. 2. Expect ICR with better Learning Engine capability. 3. Procurement of Scanning H/W and S/W in 2009. 4. Formation of 8 Data Processing Centers. 5. Utilize SMS facility for transmitting and accessing data, as well as monitoring data collection activities. 6. Utilize web-based application for monitoring data processing activities. 7. In 2008, all of 33 province level offices and some (34) district / city level offices are connected using Virtual Private Network (VPN). 17
