Interesting article

Hi all,

I heard this newsbit this morning about how researchers used cell phone towers and to track population migration after the Haiti earthquake, also during the cholera outbreak at the end of 2010 (and into the current times).  

I found the original article.  What you can see from the attached photo is an arrow that I placed on the map, pointing to Pestel.   The size of the ball indicates the # of people who migrated from Port-au-Prince to Pestel just after the earthquake.

This indicates that 10,000 people migrated into Pestel after the earthquake.   

What our household survey indicated was that 1/2 the families surveyed took in, on average, about 4 people.   If there are 10,000 families (est) in Pestel, then 5000 families took in 20,000 people.   

So we'll split the difference and say 15,000
:)
