ISO 9001 Certifications Worldwide

The variable "ISO 9001 quality certificates/bn PPP$ GDP" represents the number of ISO 9001 quality certificates per billion of GDP expressed in terms of Purchasing Power Parity (PPP). ISO 9001 certificates refer to those issued in a specific country or region, and they attest that an organization has implemented a quality management system compliant with international standards. GDP in PPP dollars accounts for differences in purchasing power between countries, allowing for fairer comparisons across price levels. In summary, this variable measures the diffusion of ISO 9001 quality certificates in relation to the economic size of a country, providing insights into how widely these certificates are adopted relative to the economic value expressed in billions of international PPP dollars. This indicator is useful for comparing the adoption of ISO 9001 certifications across economies of different scales. The data refer to the period between 2013 and 2022.
