Medellin isn’t necessarily poor, it claims to be Colombia’s most progressive city, but for this reason the poor, the displaced, and the homeless all swarm to Medellin.
The streets are full of families from the south that lost their homes due to ongoing guerrilla warfare and widespread fumigation to eradicate coca plantations. The war forces them to pick sides and the fumigation spoils their soil so most residents just pack up and leave. Some to Ecuador, others to the north.
Colombia has an estimated 4-5 million internal refugees. Second only to Sudan.
And the effects are obvious in cities like Medellin.
