This technical paper examines the major forces of change shaping Punjab’s demographic, economic, and spatial trajectory over the planning horizon to 2047. It forms the foundational analytical layer of the Punjab Spatial Strategy 2047, establishing the evidence base for long-range spatial planning by documenting Punjab’s population growth dynamics, urbanisation trends, inter-census population increments, age-sex distribution, and urban-rural population projections. The paper establishes the scale and nature of Punjab’s development challenge — providing planners with the demographic and structural context necessary to design a spatially coherent long-range strategy.
