How do you research 'World' and 'regional' industry market size totals when you don't research every country individually?

We build a model which pegs the countries we do not research individually to various of the core countries that we do research.

The core countries act as a broad guide to consumption and expenditure patterns in the neighbouring countries and, working data through a model which takes into account populations, consumer spending levels and other macro-economic factors, we produce market size estimates for every country and so genuine regional and global market size totals.

Our in-house regional specialists also factor in social and cultural issues when generating the modelled data.  This allows us to produce genuine regional and global market size totals.
