Characteristics of different residential areas

Zonation of Residential Areas

1️⃣ Inner‑City Residential Areas

Think of the city centre as the core of a fruit – the part you reach first. Inner‑city housing is usually:

• High population density – often > 10 000 people km⁻².
• Mixed‑use: shops, offices, flats all in one block.
• Older buildings with narrow streets – brick terraces or apartment blocks.
• Good public transport: bus, tram, metro stops every 2–3 min.
• Higher property prices but also more amenities (schools, hospitals).

2️⃣ Suburban Residential Areas

Suburbs are like the outer rings of a tree – a bit farther from the centre but still connected.

1. Moderate density: 2 000–5 000 people km⁻².
2. Single‑family houses, semi‑detached homes, and low‑rise apartments.
3. More green space – parks, playgrounds, and cul‑de‑sacs.
4. Transport: bus routes and commuter trains to the city.
5. Typical price range: £200 000–£400 000 (UK example).

3️⃣ Rural Residential Areas

Rural homes are the leaves at the edge of the tree – farthest from the core.

• Low density: < 500 people km⁻².
• Large plots, detached houses, farms.
• Limited public transport – usually bus only or no service.
• Strong sense of community; neighbours often know each other.
• Property prices vary widely; often cheaper per square metre.

4️⃣ New Towns & Planned Communities

These are freshly planted saplings designed to grow sustainably.

5️⃣ Factors Influencing Zonation

Think of these as the weather conditions that shape how a city grows.

• Economic activity – jobs attract people.
• Transport links – roads, rail, and public transit.
• Land values – higher prices push housing outward.
• Planning policies – zoning laws, green belts.
• Environmental constraints – flood plains, protected areas.

Mathematics Corner: Population Density

Population density helps us compare how crowded an area is.

Formula: $D = \dfrac{P}{A}$

Where $P$ = total population and $A$ = area in square kilometres.

Example – Inner city: $P = 120\,000$, $A = 10\,\text{km}^2$ → $D = 12\,000\,\text{people/km}^2$.

Quick Review Quiz

1. Which zone has the highest density? Answer: Inner‑City
2. What is a key feature of rural areas? Answer: Low density and large plots
3. Why are new towns called “planned”? Answer: They are designed with a master plan and integrated transport.
