|Title||What is mid-year population? What is the purpose of compiling mid-year population and how is it produced?|
Mid-year population refers to population as of July 1. It better represents the population in the year compared to the population at the beginning or end of year.
As recommended by the UN, KOSTAT produces vital statistics rates (i.e. birth rate, death rate, marriage rate and divorce rate) using mid-year population according to resident register as denominator. Mid-year population is computed by averaging end of year population over two years.
【ex, 2012 mid-year population = (2011 end of year population + 2012 end of year population)/2】
