Spec mapping (AQA 7037): Paper 2, §3.2.2 Changing Places — Factors contributing to the character of places: endogenous factors (location, topography, physical geography, land use, built environment and infrastructure, demographic and economic characteristics). This lesson defines and works through each endogenous factor and shows how they interact to produce place character. It links to the next lesson on exogenous factors (the two are always studied together), to §3.2.1 (because internal characteristics determine how a place plugs into global flows) and to §3.2.3 (urban land-use patterns and the built environment). Assessment objectives: AO1 — the categories of endogenous factor and the concepts behind them; AO2 — application to named UK places with contrasting characters; AO3 — interpreting demographic and deprivation data (census, IMD) as evidence of a place's internal character.
Endogenous factors are the internal characteristics of a place that shape its identity, function and character. They include its location, topography and physical geography, its land use, built environment and infrastructure, and its demographic and economic make-up. Understanding endogenous factors is essential for AQA Changing Places: they are the "raw material" of place on which external (exogenous) forces act, and they explain what a place is like even before we ask why it became that way. But a recurring exam trap is to treat endogenous and exogenous factors as if they were independent — in reality they are continually entangled, and the strongest answers show the interaction. This lesson examines each category with UK-specific, data-rich case studies and evaluation.
Key Definition: Endogenous factors are the internal, local characteristics of a place — the features that originate from within the place itself — as distinct from exogenous factors, which are external relationships and influences imposed from outside.

Exam Tip: The specification distinguishes endogenous from exogenous factors, but examiners reward integration. Physical geography (endogenous) influences transport links (infrastructure), which attract investment (exogenous), which changes land use (endogenous), which alters the demographic profile (endogenous). Trace these chains rather than listing factors in isolation.
Before the other factors, AQA lists location and topography as endogenous characteristics in their own right. Location here means the place's situation — its position relative to coast, rivers, routeways and other settlements — which historically determined why a settlement grew where it did. Topography (relief, altitude, slope and aspect) shapes where building is possible, which land is farmed, where the desirable views and the flood-prone hollows lie, and even micro-patterns of social geography (historically, higher ground attracted higher-status housing away from polluted, flood-prone valley floors).
| Endogenous characteristic | Influence on place | UK example |
|---|---|---|
| Situation/connectivity | Determines accessibility and economic function | York grew at the confluence of the Ouse and Foss and a Roman route junction — a nodal location that made it a regional capital |
| Altitude & slope | Constrains building; shapes farming; affects desirability | Steep-sided South Wales valleys forced linear, terraced settlement along the valley floors and lower slopes |
| Aspect | South-facing slopes are warmer, sunnier, more desirable | Hillside suburbs with southerly aspect (e.g. parts of Sheffield's western side) historically commanded a premium |
The physical environment is the foundation on which places develop. Geology, relief, drainage, climate and soil all influence where settlements form, what economic activities are possible, and how places look and feel.
| Physical Factor | Influence on Place | UK Example |
|---|---|---|
| Geology | Determines building materials, soil fertility, mineral resources | The Cotswolds' honey-coloured limestone buildings reflect the underlying oolitic (Jurassic) limestone; Welsh valley terraces were built from locally quarried Pennant sandstone |
| Relief | Influences settlement patterns, accessibility, views | The Lake District's mountainous terrain produced dispersed settlement, limited arable farming and later drew tourists — the National Park receives in excess of 15 million visitors a year |
| Drainage | Rivers attract settlement (water, transport, power) but create flood risk | York sits at the Ouse–Foss confluence; the city suffered severe flooding during Storm Eva (December 2015), inundating central streets and businesses |
| Climate | Affects agriculture, tourism potential, quality of life | Bournemouth's mild south-coast climate and sandy beaches underpin a large year-round tourism economy |
| Coastal position | Enables ports, fishing and tourism; creates erosion/flood vulnerability | Whitby, North Yorkshire — a former whaling and fishing port, now a tourist place shaped by its harbour setting, abbey ruins and Dracula associations |
A-Level Analysis: Physical geography was more decisive before industrialisation, when economic activity was tied directly to local resources (coal, water power, ore, fertile soil). Post-industrial places are less bound to it — a software firm can locate anywhere with fibre broadband — but physical geography still shapes quality of life, aesthetics, flood risk and tourism potential. The Peak District's physical landscape sustains a very large rural visitor economy and frames the identity of every settlement on its fringe.
Two precise terms underpin the analysis of how physical geography shaped where and why settlements grew, and using them correctly signals fluency:
The interplay explains many British places. Sheffield grew where it did because of site factors that are pure physical geography: the confluence of five rivers (Don, Sheaf, Rivelin, Loxley, Porter) provided fast-flowing water to power grinding wheels and forge hammers, while the surrounding Pennine hills supplied millstone grit (for grindstones), coal and iron ore. Its industrial specialism in steel and cutlery was therefore seeded by physical geography long before any exogenous force arrived. Once that specialism existed, however, the city's fortunes were increasingly governed by situation and by external markets — which is the bridge to the next lesson on exogenous factors. The general principle is that physical geography sets the initial conditions and possibilities of a place, but rarely dictates its long-run trajectory alone.
Land use refers to how the surface of a place is used — for housing, industry, commerce, agriculture, recreation or transport. Land-use patterns are a legible record of a place's economic history, planning decisions and social structure.
The Burgess (1925) concentric-zone model and the Hoyt (1939) sector model offer frameworks for UK urban land use, though both are simplifications:
| Model | Pattern | Relevance to UK |
|---|---|---|
| Burgess (1925) | Concentric rings: CBD, transition zone, working-class housing, middle-class housing, commuter zone | Partially applicable — many UK cities show a density gradient from inner city to suburb, but rivers, railways and historic cores create irregularities |
| Hoyt (1939) | Sectors radiating along transport routes; industry follows railways/rivers; high-status housing on higher ground | More applicable — in Leeds, higher-status housing extends north toward Headingley and Roundhay, while industry historically followed the Aire valley |
| Type of Change | Process | UK Example |
|---|---|---|
| Brownfield redevelopment | Former industrial land converted to new uses | Salford Quays — former Manchester Ship Canal docks, now MediaCityUK, BBC/ITV operations and waterfront apartments |
| Greenfield development | Building on previously undeveloped land | Cranbrook, Devon — a new community built from 2012 on former farmland near Exeter |
| Rural–urban fringe | Contested zone where urban expansion meets countryside | Green-belt land around Cambridge under intense pressure for housing — Cambridge house prices run at a very high multiple of local earnings |
| Gentrification | Working-class neighbourhoods transformed by more affluent incomers | Brixton, South London — once associated with the 1981 riots, now marked by artisan food halls, craft bars and sharply rising property prices |
The built environment encompasses all human-made structures — housing, commercial and public buildings, monuments and streetscapes. It is among the most visible indicators of a place's age, wealth and character. Housing stock in particular acts as a "time-stamp," recording the era and economy that produced it.
| Housing Type | Era | Characteristics | Where Found |
|---|---|---|---|
| Georgian terraces | 1714–1830 | Symmetrical façades, sash windows, classical proportions | Bath, Edinburgh New Town, Bloomsbury (London) |
| Victorian terraces | 1837–1901 | Bay windows, brick, high density, back-to-back or through terraces | Northern industrial cities — Leeds, Manchester, Sheffield |
| Council estates | 1919–1980s | Standardised social housing, 1960s tower blocks, low-rise estates | Nationwide — e.g. Park Hill, Sheffield (1961); Broadwater Farm, London (1967) |
| Post-war semi-detached | 1945–1970 | Pebble-dash render, front and back gardens, suburban | Suburbs of every major city |
| New-build estates | 1990s–present | Repeatable volume-housebuilder designs (Persimmon, Barratt), compact rooms | Greenfield sites on urban fringes nationwide |
Key Example: Park Hill, Sheffield, is a Grade II*-listed Brutalist estate built 1957–1961 — originally 996 council flats famed for their "streets in the sky." It became associated with crime and dereliction in the 1980s–90s, and since 2007 Urban Splash has redeveloped it as mixed-tenure housing at market rents. The transformation of a symbol of post-war social housing into a part-gentrified development shows how the same built environment is repeatedly re-read and re-valued as the social and economic context changes.
A skilled geographer can "read" a place's history and social structure directly from its built environment, much as a historian reads a document. The grain of the streets, the age and density of the housing, the presence or absence of front gardens, the materials, and the surviving public buildings all encode information about when a place was built, for whom, and under what economic conditions.
A-Level Analysis: Reading the built environment is a genuinely evaluative skill, not mere description. The presence of "hostile architecture" (anti-homeless spikes, sloped benches, blue lighting in toilets to deter drug use) tells you not just what a place looks like but whose presence its designers sought to discourage — linking the physical fabric directly to questions of power, belonging and who a place is "for." The built environment is never just scenery; it is frozen social policy.
Infrastructure — the physical systems that allow a place to function (transport, communications, energy, water, public services) — is both an endogenous characteristic and a magnet (or barrier) for external investment.
| Infrastructure | Effect on Place | Example |
|---|---|---|
| Motorway access | Attracts distribution and business parks; can sever communities | The M1/M6 corridor through Northamptonshire drew Amazon and logistics giants; junction towns such as Daventry and Corby grew rapidly around warehousing |
| Railway stations | Station towns prosper; closure brings decline | The 1963 Beeching cuts proposed closing over 2,300 stations; places such as Keswick lost their rail link and became car-dependent |
| High-speed rail | Potential to redistribute economic activity | HS2 was planned to cut London–Birmingham journeys to 49 minutes — a possible boost to Birmingham but also a "brain-drain" risk |
| Broadband | Essential to the modern economy; rural areas often underserved | Rural premises lag well behind urban areas for gigabit-capable broadband (Ofcom), constraining remote work and rural business |
| Airports | Drive tourism and business; create noise and air-quality issues | Manchester Airport supports tens of thousands of regional jobs but generates noise complaints and congestion |
A place's demographic profile — its structure by age, ethnicity, income, education and occupation — is simultaneously an endogenous descriptor and a product of wider processes (migration, economic change, housing policy). AQA explicitly pairs demographic with economic characteristics, because the two are inseparable: a place's occupational and employment structure drives its income, deprivation and even its health.
