We adapted the chord diagram plot to visualize China’s recent inter-provincial migration during2010–2015. The arrowheads were added to present the direction of the flows. This method allows us to show the complete migration flows between 31 provinces in China including the direction and volume of the flows. The spatial component was also clearly depicted in the plot using four color palates rep...

BACKGROUND Observational studies have suggested that the risks of non-communicable diseases in voluntary migrants become similar to those in the host population after one or more generations, supporting the hypothesis that these diseases have a predominantly environmental (rather than inherited) origin. However, no study has been conducted thus far to identify alterations at the molecular level...

This article presents newly-available migration data from the 1990 US census to assess immigration and internal migration components as they affect state poverty populations. New immigrant waves are heavily focused on only a few'port-of-entry' states.

Are immigrants who live in states where large numbers of their compatriots reside more or less likely to migrate than those who live in other states? Using 1980 U.S. Census data to address that question, the analysis shows that nativity concentration deters interstate migration but not migration within the same state. Residing in a state where fellow nationals live is a more important determina...

Abstract There are well‐documented associations between life course changes and migration; yet, the occurrence, order, timing of reasons for migrating growing increasingly diverse. Migration following adverse events, such as a divorce or an involuntary job loss, may be qualitatively distinct from migration undertaken other reasons. Moves, especially long‐distance moves, defined more by seeking ...

In the recent European debt crisis, internal migration flows in the euro area reacted strongly to diverging labor market conditions. This experience points towards the prominent role of short-term business cycle migration in the euro area and the consequent need to understand the motives behind it. We start by an empirical investigation of the business cycle in 59 bilateral migration corridors ...
