Abstract
We estimate the e ect of hydro-meteorological emergencies on internal migra-
tion in Costa Rica between 1995 and 2000. Nationwide, we nd that an increase of
one emergency at the canton of origin increases signi cantly, in average, migration
rates after controlling for several social, economic, climatic and demographic fac-
tors of the cantons of origin and destination. Moreover, when we analyze separately
landslides and
oods, we also nd that both increase migration. However, we also
nd that emergencies with the most severe consequences, those with loss of lives,
decrease migration. The severity of the consequences may explain the di erences
in the sign of the e ect in previous research. We also nd that emergencies will in-
crease signi cantly urban population. Less severe emergencies increase signi cantly
migration towards urban areas. More severe emergencies decrease signi cantly mi-
gration towards rural areas. This is especially important in developing countries
where cities are already facing problems associated with overpopulation.
