quality, In absolute term6, labour supply is alirectly related to overall population growth: ceteria paribus the greater the population growth, the greater the potentlal number of person.s in the labour force' Declines in mortality' such as those experienced by na ny developing countries during the Post-vtar period, have spurred population gronth. Hoeever, importantly and contrary to fer ti li ty-induced populaEion growth. population growth induced by a typical pattern of mortality decline increases the number of pergons at all aqest the size of the labour force increases along with the number of those dependent for economic suPport. It is therefore probably of rc6t interest to investigate Che effect of a decline in (Drtal,ity on relative labour supply than on absolute labour supplyt that is, the way in which typicat decline in mortality differentially affects the size of the Iabour force population and the size of the dependent Population. 217. A relativeLy simPle type of rlortallty decline that can be envisioned is one in nhich age-specific tleath rates change by an egual amount at every age. Such a mortalitv change is generally termed a neutraL change in mortality. It is called neutral because such a change has no effect on bhe population age distrlbution, the percentage of the population in each age group remains the same. Hence uqder the assuaption of unchanging rates of labour force Participation, by age and sex, relative labolr supply remains unchanged. The assumption of unchanginq rates of Iabour force participation may under sone circumstances be unrealistic. Even a neutral change in mortality generates an increased rate of population grorrth. Increased population gror,rth can give rise to social change or to structural change in the economy due to, for example, fixed amounts of Land and capital or economies of scale, which affects the level and pattern of labour force participation'
**Analysis**
The text discusses the relationship between population growth and labor supply, and how changes in mortality rates affect the size of the labor force and the dependent population. It appears to be focused on the economic implications of population growth and mortality decline, rather than other categories. The text also touches on the potential impact of increased population growth on social and economic structures, which suggests a connection to employment and economic development.
