  3. Agenda Geography in IPUMS International IPUMS-I Work Process Web Delivery Planned Enhancements

  4. IPUMS-I Geographic Variables Countries with FIRST administrative level variables Countries with SECOND administrative level variables

  5. IPUMS-I Boundary Files

  6. Agenda Geography in IPUMS International IPUMS-I Work Process Web Delivery Planned Enhancements

  7. Work Process Enable mapping of IPUMS-I Microdata Find maps* Match map data to IPUMS-I microdata Create linking fields Deliver shapefiles via the web

  8. Work Process:Matching Geographic Data to Microdata From Shapefile - Cuba From IPUMS – Cuba 2002

  9. Matching Geographic Data to Microdata From Shapefile - Cuba From IPUMS – Cuba 2002 CU02 CUB-CHB Ciudad de la Habana

  10. Agenda Geography in IPUMS International IPUMS-I work process Web delivery Planned enhancements

  11. Web Delivery Zipped shapfiles (ESRI format) Include linking codes for microdata World Map • Aggregate variables at the country level First administrative level boundary files • Aggregate variables at 1st admin level • Some variables require recoding (BPL, MIG)

  12. Sample Map:Multiple Nested Countries

  13. Agenda Geography in IPUMS International IPUMS-I work process Web delivery Planned enhancements

  14. Planned Enhancements For all samples • 2nd administrative level maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)

  15. Planned Enhancements For all samples • 2nd level administrative unit maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)

  16. 2nd Level Administrative Units Departments in Argentina Small population units combined in residual category

  17. Combining Small 2nd Level Units

  18. Planned Enhancements For all samples • 2nd level administrative unit maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)

  19. Time-specific shapefiles Departments in Argentina Start with recent map Match to recent data Add harmonized codes Data does not map Regions appear blank in earlier years

  20. Planned Enhancements For all samples • 2nd level administrative unit maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)

  21. Pilot:Creating Consistent Low Level Units Ecuador

  22. Ecuador2001 IPUMS-I Population Data1st Level Units(Province)

  23. Ecuador2001IPUMS-I Population Data Small units: Group them 20-50K: Stand alone >50K Divide units 2nd Level Units(Canton) 3rd Level Units (Parish)

  24. Creating Consistent GeographicUnits Low Level Labeled Data Detailed Maps Grouping Criteria

  25. Creating Consistent GeographicUnits Low Level Labeled Data Detailed Maps Grouping Criteria Time Specific Maps

  26. Ongoing Work Research • Resolve map to microdata mismatches • Investigate boundary changes over time • Establish grouping criteria Locate Usable Source Maps • Temporally accurate (multiple maps per country) • Spatially congruent • Detailed metadata • Public domain or permission to re-release
