How the location guides work

German business clusters rarely follow municipal boundaries. The guides state the geography used for every material figure and identify when a company, research network or labour market belongs to a wider region.

Source policy

Each guide begins with the relevant official statistical source. Company filings, regulators and infrastructure operators are used for sector detail. Promotional estimates are attributed, project commitments are not counted as completed investment, and group employment is not presented as local employment without a location-specific disclosure.
