Rapid population growth observed across the global landscape can be traced from the dawn of the last half of the twentieth century. The period is marked by enormous land use and land cover changes, the rising rate of declining biological resources as well a continuous high rate of urbanisation. Dar es Salaam City, once a fishing village but now the most industrialised and urbanised city in Tanzania, has not been spared of such changes. This article composition intended to uncover the correlation between population growth and solid waste generation in the city of Dar es Salaam. The data inputs involved Tanzania’s national population census for the years 2002, 2012, and 2022, but also shapefiles for Dar es Salaam City and the United Republic of Tanzania. Dar es Salaam city’s wards, the lowest but one administrative level in Tanzania, were central in this study as the lowest unit of analysis. Data management for this spatiotemporal study was done in Microsoft spreadsheet, while data analysis involved the use of the ArcMap platform of ArcGIS version 10.5. The results show a strong relationship between population growth and municipal solid waste generation in Dar es Salaam city. From the visual results, the overall impact of population on solid waste generation is well presented across both census years. Despite varying at different times in the twenty years of the study period, wards such as Kunduchi, Mabibo, Majohe, Mbagala Kuu, Mbezi, Mianzini, Saranga, Segerea, Vingunguti, Wazo, and Charambe produced significant amounts of solid waste. Across the study period, Vingunguti and Majohe were revealed to be the only two wards in the city that have continued generating high solid wastes. These visual results display the almost exact location of a high waste generation hence delivering information necessary for strategic and informed decision-making, henceforth, policy formulation towards solid generation and management.
