Market index

We ask 8 markets the same questions at least once a week; 6 of them clear the floor we publish on.

Each figure counts the comparable mornings — the days when every assistant answered — on which an assistant named a business we measure in that market.

A count of mornings, and not a scale.

Each figure carries its own day because the markets are measured to different days — one shared date would be true for the freshest and wrong for every other.

How a market gets a figure

A market appears above once at least 5 businesses and 4 phrasings are in one of its niches. Below that we measure it and hold the figure back.

Held today: Brazil, Maldives. Each has a page saying what we ask it and how far off the floor it is.

A market shows a figure only after 3 comparable days; before that it is listed as measuring.

A single day describes a day rather than a market.

Asked twice on one morning, the same question does not return the same names, so a figure published from one day would move on its own and read as change.

Days are compared by how many engines answered, not by date.

A day where one platform was unreachable is excluded whole.

With one engine missing there is one fewer chance to be named, and counting that day beside a full one would read as a market that went quiet.
