Table 4.

The selection process for referencing provinces for urbanization projections under fast and slow assumptions.

Scenarios	Included	Excluded
Fast assumptions	PU₂₀₁₅ < R₂₀₁₅ < PU₂₀₁₅ + 5%	ΔR < ΔPU
Slow assumptions	PU₂₀₁₅ − 5% < R₂₀₁₅ < PU₂₀₁₅	ΔR > ΔPU

PU₂₀₁₅ is the urbanization rate of the province to be projected in 2015, while R₂₀₁₅ denotes the urbanization rate of the referencing province. Δ indicates the increase in urbanization during 1995–2015, e.g. ΔR denotes changes in urbanization of reference provinces between 1995 and 2015.
