Undocumented migration in response to climate change
Journal Title: International Journal of Population Studies - Year 2015, Vol 1, Issue 1
Abstract
In the face of climate change-induced economic uncertainties, households may employ migration as an adaptation strategy to diversify their livelihood portfolio through remittances. However, it is unclear whether such climate-related migration will be documented or undocumented. In this study we combined detailed migration histories with daily temperature and precipitation information from 214 weather stations to investigate whether climate change more strongly impacted undocumented or documented migrations from 68 rural Mexican municipalities to the U.S. from 1986−1999. We employed two measures of climate change, the warm spell duration index (WSDI) and precipitation during extremely wet days (R99PTOT). Results from multi-level event-history models demonstrated that climate-related international migration from rural Mexico was predominantly undocumented. We conclude that programs to facilitate climate change adaptations in rural Mexico may be more effective in reducing undocumented border crossings than increasing border fortification.

Changes in total and disability-free life expectancy among older adults in China: Do they portend a compression of morbidity?
The purpose of this research is to determine whether disability-free life expectancy (DFLE) in China has been increasing more rapidly than total life expectancy (TLE). Such a scenario would be consistent with a compressi...

Assessments of mortality at oldest-old ages by province in China's 2000 and 2010 censuses
This study examined the possible underestimation and age-trajectories of mortality at oldest-old ages in China’s 2000 and 2010 censuses. By linking logit-transformed conditional probabilities of dying from 13 countries w...
