Claim types Estimate
Estimate. The numbers: UN DESA Population Division, World Urbanization Prospects 2025 (2025 Revision), File 21: population of cities by the Degree of Urbanisation (POP/DB/WUP/Rev.2025/F21, CC BY 3.0 IGO), read via the progrss vault (§4.11, un-wup 57/0). Method (UN WUP 2025 methodological report): city populations come from 1 km population grids (GHS-POP, every five years to 2020, projected to 2025) onto which census counts are spread and scaled to the UN's national totals; cities are places of at least 50,000 people under the Degree of Urbanisation, and their extents are redrawn for each reference year. The UN calls all years to 2025 estimates; yearly values between the five-year points are straight-line. Set: the 14 places the UN lists as cities of Zambia in 2000 (Lusaka, Kitwe, Ndola, Chingola, Kabwe, Kasama, Livingstone, Chipata, Mufulira, Kapiri Mposhi, Solwezi, Mongu, Luanshya, Monze), held fixed so that towns becoming cities later do not change the denominator. Lusaka 1,056,389 in 2000 and 3,510,723 in 2025; the other 13 together 1,669,992 and 3,150,923; Lusaka's share 38.75% in 2000, 45.08% in 2010, 48.36% in 2015, 51.70% in 2020, 52.70% in 2025. Against all 33 places the UN counts as cities of Zambia in 2025 (including Mansa, now the fourth-largest at 335,503), Lusaka's share is 41.5% and the other 32 hold more people (4.94 million); against the 13 next-largest cities of 2025 Lusaka is ahead by about 1% (3.51 against 3.47 million). Copperbelt = Kitwe, Ndola, Chingola, Mufulira, Luanshya: 936,898 in 2000 (89% of Lusaka) and 1,781,631 in 2025 (51%). Shares and ratios are progrss calculations. The pictures: true-colour median composites of dry-season (May to October) Landsat 7 scenes, 1999–2002 (65 scenes), and Landsat 9 scenes, 2024–2025 (62 scenes), under 20% cloud, USGS Collection 2 Level-2 surface reflectance, exported at about 30 m per pixel by progrss through Google Earth Engine (non-commercial registration, so this plate is not licensed); the same frame (28.06–28.51°E, 15.28–15.57°S, about 48 by 32 km) and the same colour stretch for both. The two sensors render colours slightly differently (the 2000 picture is redder); small bright specks are roofs, quarries or leftover cloud. The frame is not the UN's city boundary. Landsat data are public domain (USGS). No cause is claimed.
