Settlements & Urbanisation (Years 7–9) — Geography

Why people cluster where they do, and how towns and cities are arranged into land-use zones.

Stand in the middle of any big city and turn around slowly: towering offices, then older terraces, then leafy suburbs, then fields. A city is not a random pile of buildings — it grows in patterns, like rings in a tree trunk. Learning to read those patterns is one of geography's real superpowers.

Why this matters — More than half the world now lives in towns and cities, and the share is still rising. Understanding how settlements work helps us build places that are pleasant, fair and not gridlocked.

Site, situation and function

Site — the actual land a settlement is built on (flat, dry, near fresh water, easy to defend).
Situation — where it sits in relation to other places (near a river crossing, a coast, a route between hills).
Function — the main job a settlement does: a port, a market town, a university city, a seaside resort.

Long ago, settlers looked hard for a good site. Flat, dry land was easy to build on; a river or spring gave fresh water; a hilltop or a bend in a river was easy to defend; and nearby woodland gave fuel and timber. Many British place names still record these choices — endings like -ford (a river crossing), -bridge, -mouth (a river mouth) and -bury (a fortified place) are little clues to a settlement's original site and function.

A good site: flat dry ground, fresh water, defence and timber nearby.

The settlement hierarchy

Settlements come in sizes, from a tiny hamlet up to a huge city. As you climb the ladder, settlements get larger and rarer, and they offer more services (a village might have one shop; a city has hospitals, universities and airports).

Settlement	Rough size	Services
Hamlet	a few houses	almost none
Village	hundreds	shop, primary school
Town	thousands	secondary school, supermarket
City	100,000+	hospital, university, airport

Up the hierarchy: fewer, bigger, with more services.

Urbanisation and land-use zones

Urbanisation means a rising share of people living in towns and cities. It happens as people move from the countryside for work, and as city-born families grow. Inside a typical city you can spot rough zones, often arranged as rings around the centre.

CBD (Central Business District) — the busy heart: shops, offices, tall buildings, high land prices.
Land is dearest at the centre, so buildings rise tallest there.
Inner city — older housing and former factories, close to the centre.
Suburbs — newer, roomier housing with gardens, further out.
Rural–urban fringe — the edge where the city meets the countryside: retail parks, new estates, open land.

A simple ring model — real cities are messier, but the idea holds.

Example — A settlement began as a small hamlet at a shallow river crossing (its site). Because roads met there (its situation), it grew into a market town. As factories opened, workers arrived and it became a city — a clear case of urbanisation.

Watch out — Don't confuse site (the ground it stands on) with situation (where it is relative to other places). Site is "on"; situation is "near".
