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

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
