The dataset behind Chartwell’s analysis of membership markets.

A structured dataset covering hundreds of membership products across major organisations. Pricing histories, benefit structures and organisational attributes are normalised to support rigorous comparative analysis.

The dataset spans professional bodies, trade associations and industry networks across multiple sectors. Coverage continues to expand as additional membership areas are analysed and incorporated.

Detailed modelling allows membership organisations to be mapped against core economic drivers such as identity and operational embeddedness, revealing patterns that influence pricing power and retention.

The Chartwell dataset is available through a navigable interface, enabling continuous exploration of organisations, membership types, benefits, latest news and pricing - including joiner fees, variable price bands and YoY change.
