Bridging the boundary gap: Harmonising South Africa's 2022 census data to historical statistical boundaries in Soweto - Extended data

This repository contains data, scripts, and outputs used to harmonise South African Census 2022 population data from Police District geography to Census 2011 Sub-Place geography for Soweto. The project includes data preparation, dasymetric mapping, uncertainty estimation, evaluation, and probabilistic population projection workflows. The accompanying document, Soweto population census22 harmonisation - Extended data.docx, provides extended methodological details, supporting analyses, and additional results that complement the main manuscript, including: S1. Sub-Place dasymetric mapping estimates: detailed population estimates produced through the dasymetric mapping approach.S2. Sensitivity and uncertainty analysis: assessment of the robustness of the population estimates and quantification of associated uncertainty.S3. Purpose of population projections: rationale for developing population projections and their intended applications.S4. Population projections methodology: detailed description of the projection framework, assumptions, inputs, and modelling procedures.S5. Projection outputs: projected population estimates and associated summary results.
