HaitiIn May 2016, WFPs Vulnerability Analysis and Mapping (VAM) Unit piloted online surveys as a data collection tool, beginning in Haiti with a survey on perceptions of food security in metropolitan Port-au-Prince and surrounding areas.

The survey consisted of a short series of questions about factors influencing the food security situation in the respondents' communities.
