Changes in version 1.0.2 (2026-09-23) - The paper behind the data is now published: Katukiza et al. (2026), "Quantity and composition of domestic solid waste in Kampala City as influenced by socioeconomic factors", Frontiers in Environmental Science 14, doi:10.3389/fenvs.2026.1889921. The README cites it at the top with its BibTeX entry, and DESCRIPTION, the data documentation, the dictionary, CITATION.cff, and inst/CITATION now refer to the paper instead of the manuscript. CITATION.cff lists the paper under references. - Added a dot plot of waste per person by income level to the top of the README, replacing the boxplot in the example. - Added the article "Waste per person by income" with an interactive version of the chart (Observable Plot in a Quarto article). Changes in version 1.0.1 (2026-09-17) - Added Alex Y. Katukiza's ORCID iD, verified against the public registry, so all eight authors now carry one in DESCRIPTION, CITATION.cff, and inst/CITATION (#26). - Added the author ORCID iDs to the dataspice metadata.
