This thesis aims to discover and analyse the locals' perceptions of transit migrants in Necoclí and howthese perceptions influence their attitudes and behaviours towards the migrants. This research has beeninspired by the limited attention in existing literature towards the Colombian local communities impactedby transit migration through the Darien Gap, including their residents' perceptions and role in this type ofmigration. Ten semi structured interviews conducted to locals in Necoclí revealed the differentperceptions residents have of these migrants, varying from positive perceptions associated with economicimprovement to negative perceptions associated with tourism decline, disturbances and difficult access toresources. Locals also perceive transit migrants as human beings and as money or economy. The findingsreveal several attitudes and behaviours towards transit migrants from solidarity and empathy to suspicion,discrimination and xenophobia. Venezuelans are the transit migrants experiencing the most negativeperceptions, attitudes and behaviours from locals in Necoclí.
