I was reading this really interesting article today: https://news.un.org/en/story/2018/06/1012312 It's about remittances, or the money that immigrants send back to their families in other countries. I was very surprised at the prevalence of this form of cash transfer. Almost one in seven people in the world are affected by them! What's more is the effect that remittances can have on a society and economy beyond just a "lifeline" (as stated in the article). These cash transfers can spur development and promote sustainability in far off, rural areas. When considering how we can achieve the United Nation's Sustainable Development Goals, remittances are an important source of development funds that cannot go overlooked.
