What questions would
we like to ask in order to improve the
design and targeting of interventions and
aid in the process of monitoring
• How many are food insecure?
• Who are they?
• Where are they?
The Demographic and Health Surveys
represent an available source of
preliminary answers to these questions:
What is the process by which we are able
to analyze and map these data?
• Download raw data from DHS+
• Bring the data into SPSS
• Summarize variables of interest to us
by geographic area
• Copy the SPSS output into an Excel
spreadsheet and save as DBF file
• Import DBF file into ArcView and
map the data
Now let’s put the pieces of the
puzzle together with an
illustration using data from the
2000 DHS for Egypt
