letter to editor: decreasing total fertility rate in developing countries

In his article bellieni mentioned ‘in western countries couples have high expectative about the advantages of delayed parenthood and exploit fertility as late as possible’. decreasing total fertility rate (tfr) is the number of children who would be born per woman (or per 1,000 women) if she/they were to pass through the childbearing years bearing children according to a current schedule of age-specific fertility rates. replacement level is a figure of tfr and less than tfr it results in negative population growth rate, aging and population reduction. tfr below replacement level is an important problem in most developed and some developing countries.
