Reading the gaps on a market map: real openings and false ones

A gap on a market map is only an opening if people who would buy live or pass there and nothing already serves them. Before you treat a blank patch as an opportunity, check three things: are there people in it, could a shop legally and physically open there, and is the gap real or just missing from the data. Most blank patches on a map of competitors are parks, water, rail yards, industrial land or wealthy streets with no shops by choice.

This article is for expansion teams, franchise developers and analysts who look at a map of businesses and are asked "where should we go next?". It explains how gaps are found, the false gaps to rule out, a worked example in Paris, and an AI employee that finds the gaps and checks them.

How a gap is found

There are two common ways to find gaps, and they answer different questions.

• Fewest places: cut the area into equal parts and count the businesses of your kind in each. The parts with the fewest are the emptiest. Simple, but blind to whether anyone lives there.
• Most people for each place: count residents in each part as well, and divide. The parts where each existing business serves the most people are the most underserved. This needs population figures, which exist only in some countries (among them France, Canada, India, Thailand, Egypt and Australia; not the United Kingdom or the United States).

Ask the map in xMap Flows does this in one question: it counts a kind of place within a distance of a point, cuts the circle into a 3 by 3 grid, and names the parts with the most people for each place. A part needs at least 1,000 residents to count as a gap. Where there are no population figures, it falls back to the parts with the fewest places and says so.

The false gaps to rule out

Common false gaps and how to recognise them.

A worked example in Paris

A made-up case. A chain of children's swimming schools in Paris asks where in a 5 km circle around a point east of the centre it is most missing. The figures below are invented, to show the reading.

Made-up figures, for illustration only.

The north-east looks emptiest, but most of its land is rail yards and a cemetery, and its residents live along one edge next to the East. The East is the real gap: almost 100,000 residents, primary schools full of children, a busy market street, and one swimming school. The chain's next step is to count residents aged 0 to 9 in the East with Demographics and look for a building with a pool or the space for one.

Mistakes to avoid

• Reading the darkest patch first. The emptiest part of a map is the most likely to be a false gap. Start with parts that have many people and some shops.
• Mixing countries. A gap measured as people per place cannot be compared with one measured as fewest places. Keep them in separate lists.
• Ignoring the edge. A part at the edge of the circle may be served by shops just outside it. Move the circle and ask again.
• Forgetting the type. Count only businesses that do what you do. A gym map that includes yoga studios and dance schools hides the gap for a gym.
• Acting on one reading. Places open and close every month. A gap worth acting on should still be there next quarter.

Doing it with an AI employee

An AI employee can find the gaps across a city every month and check each one before it reaches you. The blocks, in order:

1. Schedule: the first Monday of each month.
2. Area of interest: the city, or the districts you are considering.
3. Nearby places: businesses of your kind, plus everyday shops such as cafes and supermarkets, so false gaps show up.
4. Demographics: residents in each part, where the country has figures.
5. xMap LLM: for each candidate gap, say whether it looks real or false and why, using only the counts given.
6. Show on a map and Email: the checked gaps on a map.

What arrives each month: a map with the gaps marked, and a short note on each saying why it looks real or false. Where my rival is and I am not reads a rival's branches the same way, and Neighbourhoods without a grocery store and Neighbourhoods with many people and few notaries are ready-made gap finders for two kinds of business.
