Usually nearby: what sits within a 10-minute walk of a café
Within a 10-minute walk of London's 3,106 café hexes, a pharmacy turns up 83% of the time - 2.0× as often as across the city. Here is the list that says so, Usually nearby, and the lift behind it.
In London, cafés are in 3,106 hexes - hexagons about 350 m across. Within a 10-minute walk of those hexes there is a convenience store 92% of the time, a gym 89% of the time and a pharmacy 83% of the time. A pharmacy is also 2.0× as common near a café as across the city as a whole. That list is Usually nearby, and it sits under any Score factor that counts one kind of place.
Each row gives two numbers. The first is the share of café hexes that have the other kind within a 10-minute walk. The second is how many times as often that is than across the city. The field calls that second number lift, a term from association rules: how much more often two things turn up together than chance would make likely.

The idea, in one sentence
Of the hexes with a café, how many have this kind within a 10-minute walk - and how many times as often is that than across the city? A 10-minute walk here means the places you can reach on foot within 10 minutes, along streets and paths. Take the pharmacy row:
83% - near Café
83% of London's café hexes have a pharmacy within a 10-minute walk.
About 41% - across the city
Across all of London's hexes, about 41% have one. (Worked back from the row: 83% ÷ 2.0.)
2.0× - the lift
Near a café, a pharmacy is twice as common as across the city. 1× would mean no difference at all.
Where to click
Open a Score with Café as a factor. In the Score panel each factor has its own card, and a factor that counts one kind or category of place - or one Accessibility measure that counts places - has a closed Usually nearby row on it. Open it and the list is worked out for that kind; until then nothing is asked for.

Most common
A factor that adds several kinds together has no single kind to ask about, so it has no Usually nearby row.
Two orders: Most common, and Most tied to Café
The same counts can be read two ways, and the two tabs at the top of the list switch between them.
Most common
The default. The kinds within a 10-minute walk of the most café hexes come first, so each row leads with the share (92% · 1.7×). This is what you almost always find near a café.
Most tied to Café
The highest lift comes first, so each row leads with it (6.4× · 10%). This favors rarer kinds that are far more common near cafés than anywhere else.
Most tied to Café. A poke place is within a 10-minute walk of only 10% of café hexes, but that is 6.4 times as often as across London, where the gray bar is barely there. Rare kinds, tightly tied to where cafés are.
The ＋ at the end of each row is Add Pharmacy to my map (or whichever kind the row names). It adds that kind to your Score as a new factor, More is better. A kind your Score already counts is grayed out with “Already on your map”.
The math, honestly
Two shares and one division. The share near Café and the lift are the list's own numbers for London; the city-wide share is worked back from them and rounded.

83% ÷ 41% ≈ 2.0×
Read it as: a pharmacy is within a 10-minute walk of a café hex twice as often as of a London hex in general. 'Across the city' counts the hexes that could hold a place - those with a building.
A kind is listed only when the counts can carry it:
at least 10 hexes have both a café and that kind within a 10-minute walk - a lift on five hexes is noise;
it is near at least 10% of café hexes - otherwise rare kinds would fill the list;
it is within a 10-minute walk of fewer than 90% of all hexes - a lift against near-certainty says nothing;
its lift is at least 1.2× - anything smaller is not “usually”.
Café itself, and the categories it sits in, are left out: a café is always near a café. And when a kind is in fewer than 30 hexes, there is no list at all, only one sentence: “Only [N] hexes in London have any [kind], so what usually sits near them can't be told apart from chance.”
Where places stand, never who visits them
Usually nearby says which places stand near which. It says nothing about who goes to them, or why they are there. Cafés gather in the busiest parts of London, and busy parts have more of almost everything within a 10-minute walk - which is likely why an accountant comes out at 1.7× near a café. That is a fact about where both stand, not a sign that one needs the other. The places are those Overture Maps lists (release 2026-08-19). Treat the list as decision support, not a forecast.

The link opens a Score of cafés within a 10-minute walk in London. Open the Café factor card, then Usually nearby, and switch between the two tabs. To read the walk itself in more depth, see the 10-minute walk post; for how a new factor changes the Score, see how the Score works.
Usually nearby lists the kinds of place within a 10-minute walk of one kind more often than across the city.
Lift = share near the kind ÷ share across the city. Pharmacy near Café in London: 83% ÷ about 41% = 2.0×.
Each row draws both shares as bars - yellow near Café, gray across the city - so the gap is the lift.
Most common puts the share first; Most tied to Café puts the lift first, which favors rarer kinds.
＋ adds the kind to your Score as a new factor; a kind already counted is grayed out.

Quick questions
What does Usually nearby show?
Under a Score factor that counts one kind of place, it lists the other kinds within a 10-minute walk of that kind more often than across the city, each with the share of its hexes and how many times as often (Pharmacy 83% · 2.0×).
What is lift?
The share of the kind's hexes with the other kind within a 10-minute walk, divided by the share of all hexes with it. 2.0× means twice as common near the kind as across the city; 1× would mean no difference.
What is the difference between Most common and Most tied to Café?
Most common puts first what is near the most café hexes, so it leads with the share. Most tied to Café puts the highest lift first, which favors rarer kinds such as poke at 6.4× · 10%.
Why is a kind missing from the list?
A kind is listed only when at least 10 hexes have both, it is near at least 10% of the kind's hexes, it is near fewer than 90% of all hexes and its lift is at least 1.2×. A kind in fewer than 30 hexes gets no list at all.
Does Usually nearby mean two kinds of place help each other?
No. It says where places stand, never who visits them or why. Busy parts of a city have more of almost everything, so treat the list as decision support, not a forecast.
