Agenda Geography in IPUMS International IPUMS-I Work Process Web Delivery Planned Enhancements
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
Work Process:Matching Geographic Data to Microdata From Shapefile - Cuba From IPUMS – Cuba 2002

Agenda Geography in IPUMS International IPUMS-I work process Web delivery Planned enhancements
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)
Agenda Geography in IPUMS International IPUMS-I work process Web delivery Planned enhancements
Planned Enhancements For all samples • 2nd administrative level maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)
Planned Enhancements For all samples • 2nd level administrative unit maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)
2nd Level Administrative Units Departments in Argentina Small population units combined in residual category
Planned Enhancements For all samples • 2nd level administrative unit maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)
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
Planned Enhancements For all samples • 2nd level administrative unit maps • Time-specific maps Pilot project • Create consistent small level units (approx. 20,000 population)

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