The Greeks, Indians and Chinese are presented here as world peoples in a comparative long-term perspective, assisted by graphic modelling of their spatio-temporal trends, combining the continuity of a core identity and the discontinuities between different countries and successive diasporas. The comparison is also based on spatial models of central spaces, pericentral spaces, attractive areas and diasporas in the form of a map and of growth rings. Aside from their differences, these three peoples have a global dimension stemming from the combination of a core identity, subcontinental and maritime spaces where their presence has spread over the long term, and a diaspora in Europe and the New World. These world peoples play an active role in globalisation processes at the heart of the megalopolises of Asia, Europe and the New World.
