West Africa Coastal Vulnerability Mapping: Gridded Subset of Sub-national Poverty and Extreme Poverty Prevalence

The West Africa Coastal Vulnerability Mapping: Gridded Subset of Sub-national Poverty and Extreme Poverty Prevalence represents the HarvestChoice Subnational Poverty and Extreme Poverty Prevalence data set as a one kilometer raster, and includes values within 200 kilometers of the coast. Poverty levels affect the "defenselessness" of populations in the low elevation coastal zone. These data were developed by the Harvest Choice project funded by the Bill and Melinda Gates Foundation. Harvest Choice measured 2005 poverty levels using 2005 purchasing power parity data for two thresholds: $1.25/day and $2/day international poverty lines. The $2/day threshold was selected for this mapping exercise.
To provide poverty levels in the coastal zone of West Africa.

《西非沿海脆弱性制图：分区域贫困与极端贫困发生率栅格子集》将HarvestChoice分区域贫困与极端贫困发生率数据集处理为1公里分辨率栅格形式，覆盖沿海周边200公里范围内的所有数值。贫困水平会影响低海拔沿海区域人口的灾害抵御无力性。本数据集由比尔及梅琳达·盖茨基金会资助的HarvestChoice项目研发完成。HarvestChoice以2005年购买力平价数据为基准，针对每日1.25美元与每日2美元两项国际贫困线阈值，测算得到2005年的贫困水平。本次制图工作选用了每日2美元的贫困线阈值。

本数据集旨在提供西非沿海区域的贫困水平数据。
