The correct answer is "Population explosion." This term refers to the rapid and significant increase in the world's population that has occurred since the industrial revolution. It highlights the exponential growth and the challenges it poses in terms of resources, infrastructure, and sustainability.

Optimum population refers to a theoretical situation where the number of resources available in an area perfectly matches the population size. In this scenario, there is neither overpopulation, where the population exceeds the available resources, nor underpopulation, where the resources exceed the population size. Optimum population suggests a balance between the population and available resources, ensuring that the needs of the population can be adequately met without straining the resources of the area.

The term "dependants" refers to individuals who are reliant on others for financial support, either due to being too young or too old to work. This includes children who are not yet of working age and elderly individuals who have retired and are no longer able to work. These individuals depend on others, such as parents, guardians, or the government, for their financial needs.

A sparsely populated country refers to a geographic term for a country with a low population density. This means that the country has a small number of people relative to its land area. The term "sparsely populated" indicates that the population is spread out thinly across the country, with large areas of land having few inhabitants.

A densely populated country refers to a geographic term for a country with a high population density. This means that the country has a large number of people living in a relatively small area. The term "densely populated" indicates that the population is concentrated and crowded, resulting in a high population density.

The correct answer is that some parts of the US are densely populated, while other parts are sparsely populated. This statement accurately describes the population distribution within the USA. The country has densely populated areas, such as major cities and urban centers, where a large number of people reside. On the other hand, there are also vast areas of the US that are sparsely populated, such as rural regions, deserts, and mountainous areas. The population distribution within the USA is not uniform, with variations in density across different regions.

The natural increase of a population is calculated by subtracting the death rate from the birth rate. This calculation takes into account the number of births and deaths within a population, and the difference between the two indicates whether the population is growing or declining.

Bangladesh is an example of a country with a high population density because it has a large population living in a relatively small land area. With over 160 million people, Bangladesh has one of the highest population densities in the world. Its small size and high population contribute to overcrowding and limited resources, making it a prime example of high population density.

The lack of workers to exploit the country's natural resources is not a problem associated with an overpopulated country. In fact, overpopulation often leads to a surplus of labor, resulting in high unemployment and underemployment rates. The other options, such as overcrowded cities, lack of suitable housing, and deforestation, are commonly seen in overpopulated countries due to the strain on resources and infrastructure.

Population density is calculated by dividing the total population of a given area by the total land area of that area. This calculation provides a measure of how crowded or densely populated an area is. By dividing the population by the area, we can determine the average number of individuals per unit of land, which helps in understanding the level of congestion or distribution of population in a particular region.

The Canadian Northlands is an example of a country with a low population density because it is a vast and sparsely populated region in Canada. It is characterized by its remote and rugged terrain, harsh climate, and limited infrastructure, which makes it difficult for people to live there in large numbers.

In stage one of the demographic transition model, the death rate is high and fluctuating because diseases spread rapidly in insanitary conditions. This is due to the lack of proper sanitation facilities and healthcare infrastructure. In this stage, there is a high infant mortality rate as well, which contributes to the overall death rate. As societies transition from an agricultural-based economy to industrialization, more people move away from farming and into factories or cities. This shift in occupation and living conditions can lead to overcrowding, poor hygiene, and inadequate healthcare, creating an environment conducive to the rapid spread of diseases.

In the first stage of the demographic transition model, the correct statement is that the birth rate is high, the death rate is high and fluctuating, and the total population is low and constant. This means that the population is primarily sustained by high birth rates, but the death rate is also high due to factors such as disease, famine, and lack of medical advancements. As a result, the total population remains relatively low and stable.

In stage four of the demographic transition model, the birth rate is low because more women are working and consumerism means that the cost of raising children is very high. As women become more involved in the workforce, they have less time and resources to devote to raising children. Additionally, the increasing cost of living and consumerism leads to higher expenses associated with raising children, such as education, healthcare, and other necessities. These factors contribute to a lower birth rate in stage four of the demographic transition model.

When a population pyramid has a narrow base, it indicates a smaller proportion of young people in the population. This suggests a lower fertility rate, as there are fewer individuals of childbearing age. A high fertility rate would result in a wider base on the population pyramid, indicating a larger proportion of young people. Therefore, a narrow base on a population pyramid is associated with a low fertility rate.

The correct answer is "Schools are overcrowded and many children must go without an education." This answer is not a problem associated with an aging society because it is more related to a lack of infrastructure and resources in the education system rather than the effects of an aging population. The other options, such as buildings being knocked down for bungalows, overcrowding within nursing homes, hospital waiting lists lengthening, and nightclubs closing down, are all problems that can be associated with an aging society.

When a population pyramid has a wide base, it indicates a larger proportion of young individuals in the population. This suggests a high birth rate, as there are more births occurring to contribute to the young age group. However, an ageing population refers to a population with a higher proportion of older individuals, typically represented by a narrower base in the population pyramid. Therefore, when a population pyramid has a wide base, it is less likely to have an ageing population.

The growth of the world population can be described as exponential because it is increasing at an accelerating rate over time. This means that the population is growing faster and faster as time goes on. Additionally, the growth can also be described as logarithmic because the rate of growth gradually slows down as the population approaches its carrying capacity.

In the third stage of the demographic transition model, the birth rate is falling, which means that there is a decrease in the number of births per 1,000 people in the population. The death rate is also falling, indicating a decrease in the number of deaths per 1,000 people. Despite the decrease in both birth and death rates, the total population is still increasing. This is because the decline in the death rate is greater than the decline in the birth rate, resulting in a net increase in the population size.
