II) Survivorship will increase.

IV) The fertility rate is predicted to remain high, especially in some regions

II) Survivorship will increase.

III) Overall population size will increase dramatically.

IV) The fertility rate is predicted to remain high, especially in some regions

Explanation:

The least industrialized or developing countries have a very high birth rate. This is because these countries have ineffective public policies in relation to the labor market and health. Many of its inhabitants have little access to information and sex education, as well as low access to effective contraceptive methods, which makes the birth rate in these countries very high. This will cause the size of the population to grow dramatically, especially in less industrialized and modern regions. As a result, the country's survival rate will increase considerably, since its citizens will exist in large numbers.
