1. A population pyramid shows the number or percentage of the population in each age group, divided by sex [1] [1]. A wide base indicates a high birth rate with many young dependants [1]; a narrow apex indicates few people surviving to old age, so life expectancy is low [1].

2. The ratio of the dependent population — those under 15 and over 64 — to the working-age population [1]. Calculated as (dependants ÷ working-age population) × 100 [1].

3. Any three, 3 marks each: the low-income country has a much wider base [1], because the birth rate is higher — high infant mortality, children as economic assets, limited family planning [1] [1]. The high-income country has a much wider top [1], because life expectancy is far higher thanks to better healthcare, diet and sanitation [1] [1]. The low-income pyramid narrows sharply and steadily [1], reflecting a higher death rate at every age, whereas the high-income pyramid has near-vertical sides until old age [1] [1]. The high-income country may show a bulge in the middle-aged groups [1], reflecting a past baby boom that is now ageing [1] [1].

4. Any three, 3 marks each: Anti-natalist policies — measures to reduce the birth rate, such as China’s former one-child policy [1] [1]; problems included a skewed sex ratio from sex-selective abortion, an ageing population and a shrinking workforce, so the policy was abandoned [1]. Pro-natalist policies — measures to raise the birth rate, such as France’s or Singapore’s financial incentives, tax allowances and subsidised childcare [1] [1]; the problem is that they are expensive and have limited effect, since the decision to have children depends more on housing costs and career considerations than on a payment [1]. Immigration policy — encouraging migration to fill labour shortages, as in Germany’s recruitment of workers [1] [1]; problems include pressure on housing and services and political and social tension if integration is not managed [1].

5. The settlement hierarchy ranks settlements by size and by the range of services they provide [1] — from isolated dwelling and hamlet, through village and town, to city and conurbation; as size increases, the number of settlements falls but the range of services rises [1] [1]. Sphere of influence is the area served by a settlement — the area from which people travel to use its services [1]; larger settlements have larger spheres [1]. Threshold population is the minimum number of people required to make a service viable [1]; a newsagent has a low threshold and is found in villages, while a hospital or university has a very high threshold and is found only in large cities [1].

6. A typical pattern is the Central Business District at the core, surrounded by an inner city zone of older terraced housing and former industry, then inter-war suburbs, then modern outer suburbs and the rural-urban fringe [1] [1] [1] [1]. Reasons, any two: land values are highest at the centre, because accessibility is greatest, so only high-value uses such as shops and offices can afford it, and buildings are built upwards to make the most of the small plots [1] [1]. The city grew outwards over time, so housing age and style decrease with distance from the centre, and the outer suburbs were built when cars allowed people to live further from work [1] [1]. The fringe offers cheap, plentiful land with good road access, which attracts retail parks, warehousing and business parks that need space and lorry access [1] [1].

7. Push factors are negative conditions that drive people to leave their home area, e.g. unemployment or poverty, and conflict, persecution or natural disaster [1] [1]. Pull factors are positive conditions that attract people to a destination, e.g. available jobs and higher wages, and better services, greater safety, or family already settled there [1] [1].

8. (a) Receiving country — benefit: migration fills labour shortages and often brings a younger, tax-paying workforce and cultural diversity [1] [1]; cost: it puts added pressure on housing and services and can create social tension [1] [1]. (b) Source country — benefit: the country gains remittances sent home, reduced local unemployment, and skills brought back by returning migrants [1] [1]; cost: it risks brain drain — the loss of working-age and skilled people — and family separation [1] [1].

9. Site is the actual physical land a settlement occupies, e.g. a defensible hilltop, or a dry point above a floodplain [1] [1]. Situation is the settlement’s position relative to surrounding features and other settlements, e.g. at the confluence of two rivers, or on a trade route between two larger cities [1] [1].

10. Rapid urban growth from rural–urban migration combined with high natural increase among young migrants outpaces the ability of city authorities to provide housing and services [1] [1], so migrants settle informally on unused or unsuitable land, building makeshift housing without legal tenure, sanitation or a clean water supply [1] [1], producing informal settlements, congestion, pollution and strain on existing services [1] [1]. One strategy: site-and-service schemes, in which the local authority provides a plot of land with basic services already installed — water, electricity, road access — and residents then build and improve their own home over time [1] [1] (accept self-help housing schemes, or rural development aimed at reducing the push factors driving migration to the city).

Where marks are usually lost

• Describing a pyramid’s shape without explaining the reason.
• Giving the one-child policy without any of its consequences.
• Confusing threshold population with sphere of influence.
• Listing land-use zones without explaining the pattern.
