GCRI Classification

The GCRI examines cities worldwide to narrow them down to a roster of world cities, then ranks these based on their connectivity through on 27 metrics across five dimensions: business activity, human capital, information exchange, cultural experience, and political engagement, and are categorized as follows:

• Alpha level cities are linked to major economic states/regions and highly integrated into the world economy. Alpha level cities are classified into four sections: Alpha ++, Alpha +, Alpha, and Alpha − cities.
• Beta level cities are cities that link moderate economic regions to the world economy and are classified into three sections, Beta +, Beta, and Beta − cities.
• Gamma level cities are cities that link smaller economic regions into the world economy and are classified into three sections, Gamma +, Gamma, and Gamma − cities.
• Sufficiency level cities are cities that have a sufficient degree of services so as not to be overly dependent on world cities. This is sorted into High Sufficiency cities and Sufficiency cities.
