Counting the Clues: Collecting Data in the Field

Imagine you are standing on the high street of a busy market town — say, Shrewsbury in the UK. Traffic rumbles past. Shoppers weave between stalls. A geographer walks in and asks: 'Is this street becoming too crowded for pedestrians?' You need evidence to answer that. You cannot guess — you need data. Before reading on, think for one minute: what would you count, measure, or record to answer that question? Jot down at least two ideas.

Fieldwork is when geographers go out into the real world — a river, a town centre, a forest — to gather evidence directly. That evidence is called data. There are two broad types of data: **Primary data** is information you collect yourself, first-hand, at the location. It is original and specific to your enquiry. **Secondary data** is information that someone else has already collected and published — for example, census records, satellite images, or council traffic surveys. You use it to add context or compare with your own findings. For most fieldwork, you rely mainly on primary data and use secondary data to support it. Here are the most common primary data-collection methods geographers use: **1. Tallying and counts** — You stand at a fixed point and count things as they pass or appear: cars, pedestrians, species of plant. A tally chart keeps the record organised. This works well for anything you can observe and count directly. **2. Questionnaires and interviews** — You ask people a set of prepared questions about their opinions, habits, or experiences. Closed questions (yes/no, multiple choice) give data that is easy to compare. Open questions give richer detail but are harder to analyse. **3. Measurements** — You use instruments such as a tape measure, rain gauge, flow meter, or clinometer to record precise values: river width, rainfall amount, slope angle. Measurements are quantitative — they give you numbers. **4. Field sketches and annotated photographs** — You draw or photograph the landscape and add labels explaining features. These capture spatial detail that numbers alone cannot show. **5. Environmental Quality Surveys (EQS)** — You use a scoring sheet to rate the quality of an environment (noise, litter, greenery, traffic) on a scale, for example 1–5. Different people complete the same sheet so you can compare results. Because the scores involve personal judgement, this is qualitative data. Choosing the right method depends on your enquiry question. Ask yourself: Am I counting, measuring, asking, or observing? Is the data I need numerical or descriptive? How much time and equipment do I have?
