Methodology
Aggregate counts from the DiscoLike index of 80M+ companies. Companies without a resolvable location are counted under 'unknown', and cells below the minimum count threshold are folded into an 'other' bucket. Industry and business-type categories overlap: a company carrying several labels is counted in each.
