What is an IELTS Task 1 map question?
In IELTS Academic Writing Task 1, you may be asked to describe visual information such as a graph, table, chart or diagram. Map questions normally require you to compare the same place at different times or describe a proposed layout. IELTS requires at least 150 words and recommends spending about 20 minutes on Task 1.
The four-paragraph structure
- Introduction: paraphrase what the maps show.
- Overview: state the two or three biggest changes.
- Body 1: group related changes in one area or category.
- Body 2: describe the remaining major changes and comparisons.
Do not jump from north to south to east in every sentence. The strongest answers group information so the reader can follow the transformation.
How to write the overview
Before writing details, ask: what changed most? A useful overview might mention that a rural area became more developed, that transport access expanded, or that open land was replaced by residential and commercial facilities. Keep the overview broad; save exact locations for the body paragraphs.
Map vocabulary that actually helps
to the north of, in the south-eastern corner, alongside, opposite, adjacent to, in the centre of
was replaced by, was converted into, was expanded, was demolished, was constructed, remained unchanged
Use passive forms naturally when the focus is the change itself: “The car park was replaced by a library.”
Original IELTS-style worked example
Prompt: The maps show a small riverside village in 2000 and the same area in 2025.
Main changes: farmland in the east became housing; a footbridge was replaced by a road bridge; a café and visitor centre were added near the river; the school remained in the same location.
Model overview: Overall, the village became considerably more developed and accessible, with agricultural land giving way to housing and new visitor facilities. Transport infrastructure was also upgraded, while the school was one of the few features to remain unchanged.
This overview works because it reports the dominant transformation without listing every location.
Common mistakes
- describing every feature instead of selecting the main changes;
- omitting a clear overview;
- using vague location language;
- mixing tenses when the dates clearly indicate past, present or future;
- inventing reasons, distances or numbers that are not shown;
- writing a conclusion that merely repeats the overview.
Turn the strategy into timed practice
Practise analysing the visual for 2–3 minutes, write for about 15 minutes, then use the remaining time to check tense, comparisons and grammar.

Frequently asked questions
How should I structure an IELTS Task 1 map answer?
A reliable structure is: introduction, overview, body paragraph 1 and body paragraph 2. Group changes logically by area, time period or type of development rather than describing every feature in random order.
Do I need an overview for IELTS maps?
Yes. Your overview should summarise the most important overall changes, such as urbanisation, expansion, replacement of open land, or increased transport facilities, without listing every detail.
Which tense should I use for IELTS map questions?
Choose the tense from the dates shown. Use past forms for completed historical changes, present forms for current layouts, and future or planned forms when the map shows proposed development.
Should I give opinions or reasons for map changes?
No. Academic Task 1 is descriptive. Report what changed and compare the maps; do not invent reasons unless the visual explicitly provides them.
