  2. Census Data Primary Processing Technology • 1960: Paper • 1970: Mainframe • 1980: Mainframe/minicomputer • 1990: High-end PCs and workstations • 2000: any Personal Computer Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000

  3. Data Storage and Distribution Technology • 1960: paper • 1970: ½” reel tapes for mainframes • 1st, 2nd, 3rd, 4th Counts • couldn’t they get it right the first time? • 1980: ½” reel tapes for mainframes • STF-1, STF-2 • New name, same old format • 1990: CD-ROM • 2000: The Web Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000

  4. Analysis Methodolgies • 1960: mechanical calculators • 1970: mainframe programming languages • Fortran, PL1 • 1980: command line statistical packages • SPSS, SAS • 1990: tabular spreadsheets • Lotus123, Excel • 2000: map based displays • Free GIS*-based browsers *Geographic Information Systems Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000

  5. The Analysts • 1960: a very few, very patient people • 1970: mainframe programmers • 1980: university-based social scientists with advanced computer skills • 1990: computer-literate professionals • 2000: any and everybody Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000

  6. The 2000 Picture • Processing technology: home PC • Data storage and distribution: The Web (or CDs) • Analysis: free map-based browsers • Analysts: any and everybody The 2000 Census is now a mass market phenomena, rather than a university fiefdom. Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000

  7. Universities as “Local Data Sources” Past • Universities were the primary local data source since only they had the technology (mainframes) and expertise (programmers) to access data • By agreement, North Central Texas COG provided public interface Present • University’s role now lies in • Research and Data interpretation • Teaching and training in data analysis • North Central Texas Council of Governments operates the main access site: www.dfwinfo.com Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000

  8. UT-Dallas Activities • Research and Data Interpretation • Collin County Community College District, Analysis of Service Area Characteristics and Trends • Dallas Morning News, Toxic Traps: Public Housing and Pollution • Teaching and Training in Data Analysis: 15 credit hour graduate certificate programs in • Geographic Information Systems • Quantitative Analysis of Social and Economic Data Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000

  9. Global is Local & Local is Global • Many global resources contain local data • http://www.geolytics.com/ contains the US Census on one CD • http://cronkite.pp.asu.edu/census/ Guide to Census 2000 for jounalists • Local Web sites accessible from anywhere thus unprecedented opportunities for • us to see local data anywhere in the world • anyone in the world to see our local data Ron Briggs, UT-Dallas, The Press and the 2000 Census, December 2000
