According to the Globalization and Diversity textbook (Source 1), there are many
factors to examining a country’s population. This includes: rate of natural
increase (RNI), total fertility rate (TFR), young and old populations, and life
expectancy. The first term the text mentions is the rate of natural increase
(RNI). This statistic is calculated by subtracting the number of deaths from
the number of births in a given year. This is an important factor to determining
if the country you are studying is increase or deceasing in its population. The
next term in the Globalization and Diversity textbook is total fertility rate
(TFR). Demographers place more emphasis on this factor because it gives more
insight into a country’s condition than just the birthrates. The third term stated
in the text (Source 1) is young and old is “one of the best indicators of the momentum (or
its lack) for continued population growth is the youthfulness of a population,
since this shows the proportion of a population about to enter the prime
reproduction years.” The other end of the scale is also important
because this number is useful for interring the needs of a society in providing
social services for its senior citizens. The last demographic indicator that
the textbook states is life expectancy. This information has to do with the
health and well-being in a society. This data tells the life expectancy of a
man and woman in their specific country; which also gives insight into the
health services, nutrition, and sanitation in that country. According to the
textbook, the best indicator for a population’s age and gender structure is the
population pyramid. This graph will also show if the population is increasing
or decreasing.
Figure 1: United States population growth pyramid
According to a chart census (Source 2), the United States 2014 population is
categorized under
a slow growth pyramid. Slow growth can be defined as the ratio 1:2
people thus for every one person there are two people. Even though the United
States is expressing a slow growth their population is around 329,115,000.
Figure 2: Australia's population growth pyramid
According to the Australian Bureau of Statistics’(Source 3), Australia’s population is around 23 million people. However, Australia 2013 population (Chart above) is categorized by a slow growth and could possibly be on its way to a negative growth.
