POPULATION

Population Growth & Size

Question	Ans.	Explanation
9637	A	Natural increase is calculated by difference between birth rate and death rate of a country. The highest should be S (1800), then, P (1500), R (-200) and Q (-2000).
9638	A	To calculate population increase, number of migrants should be taken into consideration. Total population increase for P, Q, R and S are 4800 (3000+1800), -2500 (-2000-1500+1000), -2700 (-200-1000+1500-3000) and 4300 (1800 + 2500) respectively. Therefore, the City P has the greatest population increase.
9848	A	Actually this question is about the 4 stages of Demographic Transition.
0041	D	Population increase = Natural increase + Net Migration Natural increase = BR – DR Net migration = no. of immigrants – no. of emigrants
0039	D	Q (China) has imposed the one-child policy. The birth rate should not be too high while the total population should be very great. Country Y is not China, but the Philippines.
9221	D	For country X, there will be increasing no. of aged people as the population growth rate is slow (only 1 per thousand). The population growth rate for country Y is too great (15 per thousand). There will be the danger of overpopulation problem. The birth rate and death rate of country Z remain high, which means a stable population growth. Notice the difference between countries X and Z, though they have the same population growth.
9344	D	The same question as 0041.
9244	B
9537	C	Family planning can only affect the birth rate of a country.
9426	A
9442	A
9425	C	Life expectancy is increasing in developing countries because of improvement in medical care and sanitation.
9226	D	Between 1840 and 1940, the growth was due to both natural increase and net migration.

POPULATION

Population Composition & Structure

Question	Ans.	Explanation
9939	D	Rapid population growth means higher birth rate and lower death rate. (D) has a sharper top (low death rate) and a wide base (high birth rate).
9326	B	The economically active population has left the rural area for urban area. Only children and the aged are left.
9835	A	The increasing number of migrants from China only increases birth rate as most of them are in child-bearing age group. It doesn’t cause the problem of ageing.
9834	A	Overpopulation is caused by too many people and insufficient food supply. Therefore, the solutions are (1) and (3) only.
9649	-	This item was deleted in exam.
9650	A	(1) and (2) are the problems commonly found in developing countries.
9937	D	In 1961, the smallest age group is 15-19. That means the time when they were born was around 1942-46, during WWII.
0051	B	For Stage II, the most important production is secondary production. So, the country is experiencing industrialization.
9634	B	The sex ratio has remained unchanged only from 1965 to 1975. (1) is not true. In 1985, there was a bulge in the economically active age group. It showed that migration took place. So, negative net migration is wrong. The height of the population pyramid increased and it shows that there was an increase in life expectancy. The base was getting wider in 1995 and it shows that birth rate increased.
9753	C	Point (3) shows that Hong Kong has 20% of children, 72% of adults and 8% of the aged. You should learn how to read this diagram.
0038	A	(3) is not related to socio-economic problems and consequences. (4) is false as the country has great working population. It doesn’t lead to the people of unemployment.
9443	A	No evidence is to support (3) and (4).

POPULATION

Population Distribution

Question	Ans.	Explanation
9535	A	Low population density in the shaded area is mainly affected by the physical factors like climate and relief.
9938	C	X doesn’t have sub-tropical climate. It has temperate monsoon climate.
0040	A	Political stability does not affect the population distribution in China.
9641	C	There should be an increase of altitude towards the west of China.
9744	D	Although most of the east China is occupied by delta and plains, it doesn’t mean that the whole area is flat and low. High mountains can also be found along the coast of Guangdong area.
9631	A	The government never encourages people to move to the coast. Rather, the Chinese government has promoted population decentralization towards the West.
9245	A	(4) is false as natural resources are abundant in the northwestern part of China, e.g. iron ore and coal.
9844	B	Land speculation is not common in area X as it is Sai Kung. The location is not attractive for development. So, (2) is false. Even the government develops country park in Sai Kung, it doesn’t force people out from the area. (4) is also wrong. For (3), the new town nearby is Ma On Shan.
9845	B	The improvement in sanitation only increases the death rate. It cannot affect the population distribution. The large no. of in-migrants from mainland China may increase the total population of Hong Kong, but not particularly in area Y.
9345	C	The diagram shows a increasing percentage of population living in the New Territories.
9435	B	Population decentralization in Hong Kong means the development of new towns in the New Territories.

POPULATION

Overpopulation

Question	Ans.	Explanation
9343	D	Overpopulation occurs when the total population is more than the food supply.
9229	D	(1) and (3) aim at reducing birth rate while (2) and (4) aim at increasing food supply.
9750	D	Overpopulation problems do not concern the population density and the income. We should rather consider the relationship between population and food supply.
9536	C	The information doesn’t clearly show the no. of people living in urban and rural areas. Therefore, we cannot imply that there is a high level of urbanization.
9538	C	Overpopulation problems are not caused by death rate. So, lowering the death rate is not a solution to the problem.
