title: Data and analysis script for "Vector diversity and malaria prevalence: global trends and local determinants"

description: Overview

We curated a dataset of global malaria prevalence and vector distribution by integrating information from multiple open-access databases. Epidemiological (Plasmodium falciparum parasite rate) and entomological (occurrence of primary vector species) data were extracted from the Malaria Atlas Project (MAP), matched in space (within 1x1 km2 of each other) and time (overlapped in study period), and aggregated to the community level. Monthly temperature and precipitation were extracted from Copernicus Climate Change Service. The sub-national (i.e., administrative units within a country) per capita gross domestic product, used as our proxy for economic condition, was extracted from Kummu et al. (2018). The final dataset consisted of 126 independent descriptions of vector community composition from 86 locations across three continents, 17 countries, and 15 years (1990-2005).
