On one of my trips to Paris I took Metro Line 6 and got off at Bir-Hakeim.

From there, a good part of the crowd seemed to be heading to the same point. The Eiffel Tower was right in front of us and, at first glance, one might think we were all part of the same flow.

But when I began to observe more closely, the scene was quite different.

There were tourists with phones in hand, people walking in a hurry, others who stopped, some who crossed toward the Seine and others who continued toward Trocadéro. Some arrived by bicycle, others came out of the metro, some were waiting for someone and others were simply passing through the area.

Everyone was in the same place.

But not everyone was there for the same reason.

And that difference made me think about something we often oversimplify when we analyze a location.

Seeing a lot of people does not mean understanding what is happening

We are used to looking at traffic, attendance or pedestrian flow figures. And of course they matter.

But counting people answers only part of the question.

Some were arriving, others were passing through. Some had time to stop; others only a few minutes. Some were looking to buy, eat or visit; others just wanted to connect to another place.

All of them could appear in the same count.

But they did not represent the same demand.

Even the same person can behave in a completely different way depending on the moment. We can walk down a street on the way to work and barely look at a single shop, come back in the afternoon with more time and stop, or return on a Saturday with our family and use that same place in another way.

The person is the same.

Their spending capacity may be the same.

What changed was their intention.

And here a difference appears that today seems fundamental to me:

Flow tells me how many people are there. But it does not yet tell me what their presence means.

That is why, when I observe an area with a lot of movement, I try not to stay only with the quantity. I begin to ask myself other questions:

  • Why are they here?
  • Where do they go next?
  • How long do they stay?
  • What need are they trying to solve at that moment?
  • What could make them stop, return or change their route?

The answers can completely change how a location is read.

A busy location is not always a location with demand

This matters in retail, but also in a real estate project, a station, a street or a public space.

A place can receive thousands of people every day and offer few reasons to stop. Another may have less flow, but people who stay longer, return often or arrive with a much more specific need.

If we only count people, both places may look attractive.

If we observe behavior, the story may be different.

And that is precisely what stayed with me from that walk in Paris.

I did not discover that flow does not matter.

I discovered that flow, by itself, does not tell the whole story.

Because behind every person there is a reason for being there.

Working. Shopping. Waiting. Connecting to another form of transport. Meeting someone. Sightseeing. Eating. Passing through. Resting.

And understanding those reasons can be far more useful than simply knowing how many people pass by.

Since then, when I see a place with a lot of movement, I try not to ask myself the most obvious question first:

How many people pass through here?

I prefer to start with another one:

What brought them here?

Because when we understand that, we begin to better grasp what that place needs, what kind of activity could find real demand there and what would probably never work, even if the flow looks extraordinary.

That day in Paris everyone seemed to be heading to the same place.

But after watching them a little longer, I understood that each of them was using the city in a different way.

And perhaps that is where a much more precise reading of any location begins:

not just counting who passes by, but understanding why they are there.

How many times have we confused a lot of movement with a lot of demand?
