About 50% of the world population is concentrated between the latitudes of

Global analyses of population by latitude show that roughly half of the world’s people live in the band between 20°N and 40°N. One comprehensive latitudinal study found that around 50% of humanity dwell within this 20°–40°N belt, which contains many of the planet’s largest population concentrations (South and East Asia, parts of the Middle East and North Africa, and populous mid-latitude regions) and thus accounts for an outsized share of global population [1]. This concentration explains why demographic pressure on resources and development indicators are particularly strong in this latitudinal zone.
