The idea that one can <i>replace</i> lost population due to low birth rates with immigrants is not plausible for most countries. Babies are born at age 0. Migrants come into a country usually at working age but then they too age into retirement that much sooner. Thus they affect the population age structure much more slowly than would a sustained increase in birth rates. <br /><br />Back in the 1990s, the UN population division looked at this concept of "replacement migration" by asking how many migrants per year would it take to keep the ratio of 15-64 years to 65+ year olds constant in various countries with low birth rates. The required numbers to offset the aging of the population are are very, very large.<br /><br />see: http://www.un.org/esa/population/publications/migration/migration.htm<br /><br /><br />Anonymousnoreply@blogger.com
