Long-distance moves are becoming more common, but they remain the exception. For most, international migration still means crossing a nearby border, not an ocean.<br><br><a href="https://ourworldindata.org/international-migrants-dont-move-far" target="_blank"><img src="https://ourworldindata.org/cdn-cgi/imagedelivery/qLq-8BTgXU8yG0N6HnOy8g/52b29637-7d81-4492-8e8f-2e46b03b7c00/w=1350"/></a>
