Data for: County-Level Spatial Analysis of Diabetes Mortality in the US–Mexico Border Region, 2018–2023

This dataset supports the spatial analysis of diabetes mortality across the US–Mexico border region at the county and municipality level, covering the period 2018–2023. The repository contains three folders: • data/raw/ — Raw input data from CONAPO (Mexico municipal population projections by year and by age-sex group, 2018–2023) and CDC WONDER (US county-level multiple cause of death, 2018–2023). Note: INEGI raw mortality microdata (defunciones_base_datos, ~780 MB) is included as a separate upload due to size. • data/external/ — Shapefiles used for mapping. Includes Mexico municipality and state boundaries (INEGI Marco Geoestadístico: 00mun.shp, 00ent.shp) and US county and state boundaries (US Census Bureau TIGER/Line 2024: tl_2024_us_county.shp, tl_2024_us_state.shp). • data/processed/ — Intermediate R data objects generated by the analysis pipeline (File 1). Includes joined county-level map datasets for crude mortality rates and age-standardized mortality rates (ASMR) for both the US and Mexico border region. Disease classification: LISTA_MEX codes 20D and 43I (Mexico); ICD-10 codes E10–E14 (USA).Age standardization: WHO World Standard Population 2000–2025.
