# 3.8 HUMAN POPULATION DYNAMICS Lab

```BACKGROUND
Throughout much of history, human populations have been characterized by relative stability―high birth rates and high death rates fluctuating
around a low growth equilibrium. For thousands of years, the large number of births were canceled by the large number of deaths. Following the
Neolithic Revolution, when agriculture was developed, humans were able to transition from a nomadic hunter-gatherer lifestyle to a more sedentary
lifestyle. The ​infant mortality rate (infant deaths/1000 live births) was high, which led to an increase in the ​total fertility rate ​(the average number
of children born to each woman).
1. Identify two likely reasons why the ​infant mortality rate w
​ as high.
2.
Explain why a high infant mortality rate would lead to a higher ​total fertility rate​.
Dramatic changes followed the Industrial Revolution 250 years ago, when improvements in food supply and changes in health and hygiene triggered
unprecedented population growth. Around 150 years ago, significant improvements were made in the medical field that extended life expectancy.
3. Identify two medical advancements that likely extended life expectancy.
A positive ​rate of natural increase (RNI) is an increase in the number of people because the ​crude
birth rate (or ​CBR​: births/1000 people) exceeds the ​crude death rate (or ​CDR​: deaths/1000 people).
RNI is expressed as a percentage.
4. What does “percent” mean? Express percent as a fraction.
5.
What does “crude” mean? Express crude as a fraction.
6.
Explain why dividing CRUDE data by 10 results in a percentage. Express this information mathematically.
The ​World Population Data Sheet includes ​demographic
information for every country in the world.
7. Complete the table to the right for the world and for
developed countries.
8. In addition to the demographic information on the table
to the right, what other useful information is found in
this data sheet?
PROCEDURE: NIGERIA CALCULATIONS
After lurching from one military coup to another, Nigeria now has an elected
leadership. But the government faces the growing challenge of preventing
Africa's most populous country from breaking apart along ethnic and
religious lines. Nigeria's insecurity has added to its economic woes,
hindering foreign investment. The former British colony is one of the world's
largest oil producers, but few Nigerians, including those in oil-producing
areas, have benefited.
1. Based on the above information, ​identify and ​describe how Nigeria
would compare with the world in each category.
a. CBR
b. CDR
c. Infant Mortality
d. TFR
Consult the ​World Population Data Sheet to

DOUBLING TIME
6. If a population’s growth rate (%) increases at a constant rate, it is possible to
calculate the amount of time it will take for that population to double, known as
doubling time​. To approximate this quantity in years, divide 70 by the growth rate,
according to the formula to the right.

PROCEDURE: INDIA CALCULATIONS
India is the world's largest democracy and, according to UN estimates, its
population is expected to overtake China's in 2028 to become the world's
most populous nation. As a rising economic powerhouse and nuclear-armed
state, India has emerged as an important regional power. But it is also
tackling huge, social, economic and environmental problems. Home to some
of the world's most ancient surviving civilizations, India is both vast and
varied in terms of people, language and cultural traditions.

would compare with the world in each category.

PROCEDURE: CHINA CALCULATIONS
China is the world's most populous country, with a continuous culture
stretching back nearly 4,000 years. Many of the elements that make up the
foundation of the modern world originated in China, including paper,
gunpowder, credit banking, the compass and paper money. China stagnated
for more than two decades under the rigid Communist rule of the founder of
the People's Republic, Mao Zedong. But China now has the world's
fastest-growing economy and is undergoing what has been described as a
second industrial revolution.

would compare with the world in each category.

PROCEDURE: MEXICO CALCULATIONS
Mexico is a nation where affluence, poverty, natural splendour and urban
blight rub shoulders. It has the second-largest economy in Latin America, and
is a major oil exporter. But prosperity remains a dream for many Mexicans,
and the socio-economic gap remains wide. Rural areas are often neglected,
and huge shanty towns ring the cities. Many poor Mexicans have sought to
cross the 3,000-km border with the US in search of a job, but in recent years
more Mexicans immigrants have returned to Mexico than migrated to the US.
22. Based on the above information, ​identify and ​describe how Mexico
would compare with the world in each category.

PROCEDURE: FRANCE CALCULATIONS
France is known the world over for its cuisine, fashion, culture and
language. A key player on the global stage and a country at the political
heart of Europe, France paid a high price in both economic and human
terms during the two world wars. The years which followed saw protracted
conflicts culminating in independence for Algeria and most other French
colonies in Africa, as well as decolonisation in south-east Asia. France was
one of the founding fathers of European integration as the continent
sought to rebuild after the devastation of the Second World War.

interests and an unmatched global reach. America's gross domestic product
accounts for close to a quarter of the world total, and its military budget is
