The first four pillars of the GCTCI very closely reflect those of the GTCI, using all data that could
either be collected at the city level or for which the use of national data (i.e., those used in the
GTCI model) made sense at the city level.
The main difference introduced in this year’s version of the GCTCI model concerns the ’right-hand
side’ of the model. Former pillars 5 and 6 have now been replaced by one single pillar called ‘Be

a city’s ability to develop global knowledge skills (measured through its tertiary-educated workforce
and population), as well as by its global transport connectivity (measured by the presence of
international airports) and its role in international relations (measured through the presence of
The number of cities covered in the GCTCI has grown from a total of 46 last year to 90 in this
edition of the report. Using the same holistic definition of talent as the GTCI model, GCTCI uses a
significantly smaller number of variables to assess the talent competitiveness of cities.
The final GCTCI scores have been calculated as the average of the corresponding five pillar
scores of each city.
