While mortality decline has presented less of an explanatory challenge than fertility decline, there has been ample debate about its causes. This classic model is based on the experience of Western Europe, in particular England and Wales. For every subject you can now access each digital resource as soon as it is ordered. The rate of population growth in pretransition and posttransition societies is dwarfed by the rate of growth in transitional societies—a result of the time lag between the mortality and fertility declines during the process of transition and, additionally but not universally, a temporary fertility increase early in the transitional stage.

It states that the population will eventually stop growing when the country transitions from high birth rates and high death rates to low birth rates and death rates, stabilizing the population. High-mortality societies are often characterized by low technology in producing goods; in such a situation as exemplified by many agricultural and mining societies , children may be economically useful to perform low-skilled work tasks.

Based on the data collected in the final chart above, speculate in which stage of the classic demographic transition model each of these countries would fall.
