2. 2 Outline n Introduction (Motivation) n Results: u Technical features and benefits u DEMO n Conclusions u Limitations u Future Developments

3. 3 n Aim/Goal of this research: u to “digitalize” the government’s interface, so as u to provide faster data to the public, u at less expensive delivery costs of 2001 Census data. n Method (…or ways to improve customer satisfaction): u Since graphs (visualization) are better than tables, u Internet is better than printouts, and u drill-down is better than scrolling, the basic strategy was to use SAS (http://www.sas.com ) GRAPH with ODS to provide the Administrative Area/ Geographic Information System (AA/GIS) functionalityhttp://www.sas.com n Tactic: After researching typical public usage behavior, the SW was used to develop u a logical search u logical comparison, u logical ranking, and u logical presentation of the 2001 Census Data Introduction

4. 4 e.g., Ethnic diversity table:

5. 5 Ethnic diversity map (w/ Croats):

6. 6 Ethnic diversity map (w/out Croats):

7. 7 Results: Technical Features and Benefits of the Administrative Area GIS n Technical features: u Developed using SAS base and GRAPH with ODS (Output Delivery System) and intensive macro programming (25+ macros) u New administrative borders (at the county/ municipality level) for the first time implemented and used in SAS GRAPH maps (based on coordinate data provided by Croatian Geodesic Institute) u 16 consult. days (design + development) u 1114 files (html [frame, content, body], gif) u 4000+ graphs (maps, bars, pies, pin charts, “pyramids”) u multiple links u No additional intervention in HTML code (generated by SAS ODS) was necessary u Full national language support (čžš) available

8. 8 Results: Technical Features and Benefits of the Administrative Area GIS n Benefits: u Global view of demographic data (e.g., “diversity maps” for immediate insight) u Easy comparison, ranking, and identification of percentages (e.g., % illiterate) by geographic region (counties, municipalities), by name, or by rank (using “4 graphs views”) u Logical “drill-down” by geographic dimension (from counties to municipalities) u Individual graphs (maps, bars, pies, pin- charts, “age pyramids”) are readily available for download

9. 9 Results: DEMO n Site map n Ethnicity graphs and “drill-down” n Population by education n Main Table (“Other attributes”) n Age pyramids n Population density

14. 14 DEMO: Age Pyramids graphs ethnicity age education gender households Other age pyr.

15. 15 DEMO: Population Density graphs ethnicity age education gender households Other density

16. 16 Conclusions n Aims were accomplished due to: u SAS/ ODS flexibility in creating HTML linked files, tables, graphs u CBS staff expertise, collaboration with CAIR Research Center (http://www.cair-center.hr )http://www.cair-center.hr u AA/ GIS data made available with the cooperation of Croatian State Geodetic Administration

17. 17 Conclusions n Limitations: u Pilot project (time & budget constraints) u 4 demographic tables only (more later) u Graph types limited to maps, bar/pie/”pin” charts, pyramids (customer key needs) u Dimensionality (1-2 variables at the time) u GIF graphics files used only (because Java, Activex were too large and slow) u Lowest administrative unit was municipality u Zagreb town “quarters” AA/GIS data not available at development time

18. 18 Conclusions n Future developments: u English version u Additional tables and attributes (e.g., financial/economic) u Multiple variable analyses/presentations u “drill-down” to the lower level administrative units (settlements) u Zagreb town quarters AA/GIS data u Fully functional street-level SAS/GIS?
