It's difficult to tell. I get the numbers from ISS and the UN.
The country is big. People will return home. I think you should take that as an average of the number of people who end up moving, who are displaced from one place to another, and who go back home. However, what often happens is that what you call “home” is sometimes a place you have been for only two years as a result of previous violence. As well, what happens is that people who settle in temporary or informal settlements have to be relocated to another place as they follow the different patterns of violence.
I wouldn't be able to tell you directly if you should assume that some people are returning home in that 5,000 or if it's new displacement, but whatever the type of displacement, it means that if people develop networks for 6 to 12 months, even if they are not home, they've found a way to get food, some sort of security, and some sort of permanence. This uprooting, particularly if it's caused by violence or insecurity, is a challenge even if they return home. Returning home often means finding somebody occupying your land and your house and trying to recreate those networks.
