Description

Definition
NDVI_APR reports the maximum normalized difference vegetation index (NDVI) value within a 10 kilometer circular buffer around each DHS cluster location during April, averaged over the 2000-2016 timeframe. NDVI is a numeric, normalized index that measures live greenness in an area and can be used as a proxy for vegetation. Other variables in this series report maximum NDVI for other months.

Please see the User Note on Using IPUMS-DHS Contextual Variables: NDVI [URL omitted from DDI.] for the data source, methodology, and more detailed information about this variable. This variable, like the other IPUMS-DHS contextual variables, is based on sources outside The DHS Program, with values around DHS sample cluster points calculated by IPUMS-DHS staff.
