RESEARCH PRIORITY · V1.0.0

Start with the score.
Add context as you learn.

Research priority = the published Global Consumer Opportunity score. This edition needs only the released score, country, U.S. market, and source release. All 69 published leads can be explored now.

Community Bridge evidence appears beside each lead. City Population, Country Conversion, and Upstream Match Strength are optional context. They do not block this edition, and we do not add them to G again. G already contains upstream conversion, community, and affinity signals.

Higher G scores appear first. Equal scores share a priority rank; source lead IDs keep their original meaning. This identifies country-to-U.S.-market research priorities. It does not assign every foreign city a compatibility score or measure an existing partnership’s performance.

The earlier five-component international-city model remains available as a separate method. A new global city ranking can follow its own revised definition without holding back this research release.

WHAT IT MEANS

Understand the question.

This source measure describes an upstream match involving U.S. market areas. Its meaning should stay attached to the places that were actually compared.

Why it matters

A strong match in one research stage can be useful evidence. It should not quietly become a score for a different pair of places.

PUT THIS TO WORK

Which two places were matched?

Imagine two U.S. markets share similar patterns. That can help you find a useful comparison at home. It does not automatically tell you which foreign city to choose. A match keeps its meaning only when you keep the original places attached. This component comes from an earlier U.S.-market matching stage.

Follow the lead back through the Sister City methodology. Use the upstream match as context, then investigate the international place on its own terms. The city directory helps locate a potential counterpart. The supplier guide helps you ask whether the businesses actually complement one another.

Three steps you can take

  1. Identify the U.S. places and source release behind the match value.
  2. Write down the international relationship you are considering, including the city and purpose.
  3. Gather direct evidence about the foreign partner instead of transferring a domestic match score to a new city pair.

How the measure is used

Retain the original match score, the matched U.S. places, the source method, and the release identifier.

The documented source describes a U.S. market’s strongest upstream U.S.-market match. It does not directly measure a U.S. city’s fit with a named foreign city.

Evaluate whether this signal serves a revised international-city purpose. It can be omitted in a new version if its meaning does not fit.

Available results and rankings

  • The released leads include S values and country-to-market identifiers.
  • The existing website preserves the source values without inventing a new international-pair calculation.

Coverage and limits

  • The connected lead export does not provide the full upstream match calculation.
  • U.S.-market affinity and international city compatibility are different research questions.

Choose your next useful step.

Keep the original match as background research. Build the next conversation around the actual businesses, institutions, and places that would work together.
