Summary
According to the article by William W. Murdoch, Fang-l Chu, Allan Stewart-Oaten, and
Mark Q. Wilber, the world's population is projected to shoot to over 11 billion people by 2100
with only about 4 billion of people coming from the Mid-African countries due to dropping Total
Fertility Rate. The four authors compared the demographic history of 61 MACs and other
developing countries to determine the Total Fertility Rate that was found to be more than or
greater than 6 in all cases between 1950-1955 and later started to decline. Both the MAC and
ODC fertility projectors are attributed to some significant factors, such as the declining desire for
larger family size. However, the main factor attributed to the decline in the population if the
population's wellbeing. According to the authors, fertility and wellbeing are positively correlated
with a percentage of over 54%, in that when the community is low, the population experience
good health as the available resources feed sustains the entire population. In summary, the
authors feel that a drop in the fertility rate reduce population growth and thus leads to population
wellbeing. Additionally, the authors used the infant survival rate as a proxy to wellbeing
attributed to enhanced medical services.

Reaction
According to the authors, the decline in total fertility rate among the MACs is a good
representation of population wellbeing; however, I think that the term wellbeing covers a wide
range and not only fertility rate. I tend to disagree in opinion with Murdoch, Chu, Stewart, and
Wilber (2018), when women or men are unable to conceive when all factors are constant, then it
is a clear indication that there are several underlining health issues that block the copulation as
well as fertilization of couples to enhance average birthrate. Therefore, I would say that it's
unrealistic to determine the population's wellbeing with the fertility rate of the country.

Summary
The article by Max Roser is focused on determine the future population growth that has
caused demographic transition implications. According to the article, population growth is
controlled by both birth and death rates. By the UN projections, global population growth will
come to an end since the demographic history of many countries has already ended. This is
attributed to the reduced global fertility rate; thus, by the time population growth will read, 0.1%
of the world population will come to an end. According to the article, the main reason why the
world population growth is coming to an end is 'peak child' due to the increasing adult
population and decreasing child population. The second reason why the population growth will
come to an end is the perception that when the global number of deaths approach the number of
global births, the difference tends to be zero, thus leading to a zero population growth. According
to the article, by 2100, about 8 out of 10 people in the global population will be leaving either in
