So now we're doing evaluation in Burundi. Based on the data I've entered so far (about 20 percent of surveys), my impression is that the sample of people we are interviewing is going to be the youngest of all the places we are surveying. Which makes sense when you go to a village and see tonnes of kids running around and lots of young adults. I suppose I could look up and see what the stats are on average lifespan etc, or you could, but either way I know it's overall a young country, demographic wise.
