The currently large differences among the regions in the totar dependencyratio are expected co diminish by 2000 and be reversed by 20251 as Ehe ratio goesup slightly in the more developed regions and declines markedly in the lessdeveloped regions. By the year 2025, the total dependency ratio lrill range from45.5 for South Asia to 64.9 for Africa, compared rrith 59.0 in the more developedregions. rn all regions, the chird lunder 15) dependency ratio wilr decl.ine andthe old age (over 64) ralio will increase. fn the more developed regions, Cheincrease in the number of persons over 64 years of age will be greater than thedecline in the number of persons under 15 years of age, and the working agepopulation wilr increase slowly. conseguently, the total depenalency ratio wilrincrease to 59,0 in 2025 from 52.6 in 19g0. In the less developed regions, incontrast' the decline in the chird dependency ratio is expected to be much greatertttan the increase in the ratio of adults over 64t as a result, the total agedependency ratio is projected to be much lohrer in 2025 than i! is currentlv -50.5 versus 77.9. 203. fn this section attention h'itl be given to che possible affects of fertiti.ty,mortality. internal migration and international migration on the supply of labourand emproyment. To a considerabre extent it is difflcult, lf not artificial, toonly deal with a one-way causality. In most cases the relationship betrrreendemographic variabres and the supply of rabour is ci.rcular and not unidirectional.Consequently, mention is made of some of the feed-back effects as well.
**Analysis**
The text appears to be discussing demographic trends and their impact on the labor market and employment. It mentions the total dependency ratio, child dependency ratio, and old age ratio, which suggests a focus on population dynamics and their effects on the economy. The text also touches on the relationship between demographic variables and the supply of labor, indicating a connection to employment and economic development.
