The definition changes the market
A CFO-only query excludes finance directors, VP Finance, controllers, and part-time advisers. Adding those titles can be commercially sensible, but it creates a different denominator. The same issue is stronger for marketing and HR, where many smaller companies do not use a C-level title.
Country fields are also incomplete in any commercial people database. A country-filtered count measures observable indexed records under that field, not the true population.
