<h1>Journeys</h1>
<p id="desc" style="margin-bottom:50px; margin-top:20px;">This Chapter describes the journeys of refugees both on a global and local scale. The first section shows refugee flows from origin countries to host countries and viceversa. The other two sections use storymaps to narrate individual journeys of refugees seeking safety away from home. </p>
