Editing Gini coefficient (section)

===Changes in population===
Changing income inequality, measured by Gini coefficients, can be due to structural changes in a society such as growing population (increased birth rates, aging populations, emigration, immigration) and income mobility.<ref name=Kwok10>{{cite web|title=Income Distribution of Hong Kong and the Gini Coefficient|author=KWOK Kwok Chuen|year=2010|publisher=The Government of Hong Kong, China|url=http://www.eabfu.gov.hk/en/pdf/income.pdf|archive-url=https://web.archive.org/web/20101227043822/http://www.eabfu.gov.hk/en/pdf/income.pdf|archive-date=27 December 2010}}</ref>

Another limitation of the Gini coefficient is that it is not a proper measure of [[egalitarianism]], as it only measures income dispersion. For example, suppose two equally egalitarian countries pursue different [[immigration law|immigration policies]]. In that case, the country accepting a higher proportion of low-income or impoverished migrants will report a higher Gini coefficient and, therefore, may exhibit more income inequality.
