paragraph_text: Voluntary and forced migration
  
  Migration is usually divided into voluntary migration and forced migration. The distinction between involuntary (fleeing political conflict or natural disaster) and voluntary migration (economic or labour migration) is difficult to make and partially subjective, as the motivators for migration are often correlated. The World Bank estimated that, as of 2010, 16.3 million or 7.6% of migrants qualified as refugees. This number grew to 19.5 million by 2014 (comprising approximately 7.9% of the total number of migrants, based on the figure recorded in 2013). At levels of roughly 3 percent the share of migrants among the world population has remained remarkably constant over the last 5 decades.
