Choosing among possible IB Geography IA topics is less about finding an unusual idea and more about selecting a question you can investigate reliably. The strongest topics have a clear spatial element, connect to geographical theory, permit substantial primary data collection, and remain manageable within the available time and word limit.
This guide provides practical fieldwork ideas for urban, rural, coastal, river, and school environments. It also explains how to focus a question, select suitable methods, and avoid topics that sound impressive but produce weak evidence.
What makes an IB Geography IA topic workable?
The IB describes Geography fieldwork as an investigation leading to a written report based on a fieldwork question, information collection, analysis, and evaluation. Under the course assessed from 2019, the report has a maximum of 2,500 words, is allocated approximately 20 hours, and contributes 25% at SL and 20% at HL. Requirements can change between syllabus cycles, so follow the guide and teacher instructions for your examination cohort.
A workable topic normally meets five tests:
- Geographical: It investigates a spatial pattern, process, interaction, or difference.
- Focused: It examines measurable variables within a defined local area.
- Fieldwork-based: It allows meaningful primary information to be collected directly.
- Analytical: It produces evidence that can be mapped, graphed, compared, or tested.
- Feasible: The sites are safe, accessible, and suitable for repeated measurements.
A familiar topic is not automatically weak. A carefully executed study of pedestrian density or downstream river change is usually stronger than an original but impractical question based mainly on secondary research.
A reliable formula for your fieldwork question
A useful starting structure is:
To what extent does [measurable variable] change with [distance, location, land use, or environmental condition] in [specific study area]?
For example, “Is Riverside Park sustainable?” is too broad and subjective. A stronger question is: “To what extent does environmental quality improve with distance from the main visitor entrance in Riverside Park?” This identifies a spatial relationship, measurable variable, and precise location.
Beginning with “to what extent” does not automatically make a question analytical. You still need appropriate variables, sufficient variation between sites, and a sampling strategy capable of producing reliable evidence.
Accessible IB Geography IA topics and methods
Adapt these ideas to named local sites and the conditions you can observe. Your final question should be more specific than the examples below.
| Topic area | Adaptable fieldwork question | Possible primary methods |
|---|---|---|
| Pedestrian activity | How does pedestrian density vary with distance from the centre of [place]? | Timed counts, land-use classification, annotated photographs |
| Environmental quality | How does environmental quality change along a transect through [district]? | Bipolar surveys, traffic counts, noise readings, litter counts |
| Urban microclimate | How does land cover influence temperature within [area]? | Temperature readings, shade estimates, surface classification |
| Public transport | How does accessibility vary across [district]? | Walking times, service observations, stop-quality scoring |
| Park use | How does use of [park] vary by distance from entrances and facilities? | User counts, activity mapping, facility inventories |
| Tourism pressure | How does visitor pressure affect environmental quality at [site]? | Visitor counts, litter surveys, path-width measurements |
| River characteristics | How do channel characteristics change downstream along [river]? | Width, depth, velocity, sediment size and roundness |
| Coastal processes | How do beach characteristics vary along [beach]? | Beach profiles, sediment measurements, groyne observations |
| Vegetation disturbance | How does vegetation cover vary with distance from a path? | Quadrats, cover estimates, species counts, soil compaction |
These topics use relatively inexpensive, repeatable methods. Many require only recording sheets, a timer, measuring tape, basic weather instruments, or mapping software, although school-approved equipment should be used when accuracy or safety matters.
Choosing an idea for your location
Cities, suburbs, and small towns
Urban transects can reveal changes in land use, traffic, noise, pedestrian density, building height, and environmental quality over short distances. The Warsaw CBD and quality-of-life exemplar shows how distance from a central business district can provide spatial structure.
A small town does not need a major CBD. You could investigate bus-stop accessibility, pedestrian activity around schools, land-use change along a high street, or environmental quality around parks. Conduct a pilot survey because differences between sites may be subtle.
School campuses
A campus can support investigations of temperature, shade, surface cover, noise, litter, vegetation, or pedestrian flows. A suitable question might ask how surface type influences temperature across the campus between specified times.
Repeat measurements at the same sites and times across several days where possible. This reduces the chance that one unusual event determines the entire pattern.
Rivers, coasts, and natural areas
Physical geography can produce precise quantitative evidence, but safety and access come first. Use teacher-approved river sites and account for tides, waves, unstable cliffs, recent rainfall, and changing weather during coastal or river investigations.
Record environmental conditions and sampling times. These contextual observations help explain anomalies rather than encouraging you to remove inconvenient results.
Match your methods to the question
Every method should provide evidence needed to answer the fieldwork question. Additional measurements do not improve an IA if they are irrelevant or never analysed.
For each method, decide:
- What variable will be measured?
- Why does it help answer the question?
- Where and when will measurements be taken?
- How will sites or participants be selected?
- How will reliability be improved?
- What ethical or safety controls are required?
Use systematic sampling for measurements at regular intervals along a transect. Stratified sampling suits areas containing distinct zones, such as commercial, residential, and recreational land. Random sampling can reduce deliberate selection bias, but it may produce inaccessible locations.
Take repeated measurements where practical. Three sound readings at each location are more representative than one reading affected by a passing emergency vehicle. Record anomalies honestly and explain how you calculated representative values.
Plan the analysis before collecting data
Before entering the field, sketch the maps, graphs, and statistical techniques you expect to use. Suitable approaches include:
- Located symbols for pedestrian or traffic counts
- Scatter graphs comparing quantitative variables
- Transect graphs showing change with distance
- Bar charts comparing zones or site categories
- Spearman's rank correlation where appropriate
- Measures of central tendency and spread
- Annotated land-use or environmental-quality maps
Do not select a statistical test merely because it appears sophisticated. It must suit the variables and sampling design, and its result still requires geographical interpretation. A traffic-noise correlation, for example, could reflect vehicle type, street width, building form, or temporary congestion rather than traffic volume alone.
Topics that often fail, and how to repair them
| Weak idea | Main problem | More workable version |
|---|---|---|
| Is my city sustainable? | The scale and concept are too broad | How does recycling provision vary among three land-use zones? |
| How has climate change affected my town? | Local fieldwork cannot establish long-term causation | How does tree cover affect midday temperature at selected sites? |
| Are people happy with public transport? | “Happy” is vague and opinion-based | How do service frequency and walking distance influence bus-stop use? |
| How polluted is the river? | Pollution requires defined indicators and suitable testing | How do observable water-quality indicators vary around a named land use? |
| How has tourism changed the economy? | Historical economic evidence may be inaccessible | How does visitor density relate to environmental quality at an attraction? |
Questionnaires can support human geography fieldwork, but self-selected online responses often lack a strong spatial basis. Combine questionnaires with observations, mapping, environmental measurements, or counts whenever possible.
Ethics, safety, and academic integrity
Collect only information necessary for the investigation. Obtain voluntary consent for questionnaires, avoid identifiable personal details, and allow participants to decline. The ethical Geography fieldwork guide covers consent, anonymity, safe site selection, accurate recording, and citation.
Field information must be recorded honestly, including missing values and unexpected results. Although classes may share some fieldwork data under teacher supervision, each student's report, analysis, and evaluation must remain individual work.
Final topic-selection checklist
Before committing to a question, check that you can:
- Identify enough contrasting sites or observations for meaningful analysis
- Collect more than one relevant form of primary information
- Investigate a clear spatial pattern, relationship, or comparison
- Connect the question to geographical concepts or processes
- Justify the sampling strategy and each method
- Manage access, permission, equipment, weather, and safety
- Analyse the evidence within the 2,500-word limit
Reviewing IB Geography IA exemplars can show how focused questions lead to effective maps, analysis, conclusions, and evaluation. Use exemplars to understand structure, not to copy a question designed for another location.
Conclusion
The best IB Geography IA topics are focused, local, measurable, and practical. Start with an accessible location, identify a genuine spatial relationship, select repeatable methods, and plan the analysis before collecting data.
