Results showed that future greenspace exposure inequality and change rates are generally higher (1.1–2.7 times) in northern China than in southern China. Under the SSP3–7.0 and SSP5–8.5 scenarios, greenspace exposure inequality is more pronounced and grows faster for older and less educated women, as well as in megacities.
