While antimicrobial resistance is an urgent global problem, substantial clinical surveillance gaps exist in low- and middle-income countries (LMICs). We fill the gaps in the global prevalence map of nine pathogens, resistant to 19 (classes of) antibiotics (representing 75 unique combinations), based on the robust correlation between countries’ socioeconomic profiles and extensive surveillance data. Our estimates for carbapenem-resistant Acinetobacter baumannii and third-generation cephalosporin-resistant Escherichia coli benefit over 2.2 billion people in countries with currently insufficient diagnostic capacity. We show how structural surveillance investments can be prioritized based on the magnitude of prevalence estimated (Middle Eastern countries), the relative prevalence increase over 1998 to 2017 (sub-Saharan African countries), and the improvement of model performance achievable with new surveillance data (Pacific Islands). Surveillance is critical in containing globally increasing antimicrobial resistance (AMR). Affordable methodologies to prioritize AMR surveillance efforts are urgently needed, especially in low- and middle-income countries (LMICs), where resources are limited. While socioeconomic characteristics correlate with clinical AMR prevalence, this correlation has not yet been used to estimate AMR prevalence in countries lacking surveillance. We captured the statistical relationship between AMR prevalence and socioeconomic characteristics in a suite of beta-binomial principal component regression models for nine pathogens resistant to 19 (classes of) antibiotics. Prevalence data from ResistanceMap were combined with socioeconomic profiles constructed from 5,595 World Bank indicators. Cross-validated models were used to estimate clinical AMR prevalence and temporal trends for countries lacking data. Our approach provides robust estimates of clinical AMR prevalence in LMICs for most priority pathogens (cross-validated q2 > 0.78 for six out of nine pathogens). By supplementing surveillance data, 87% of all countries worldwide, which represent 99% of the global population, are now informed. Depending on priority pathogen, our estimates benefit 2.1 to 4.9 billion people living in countries with currently insufficient diagnostic capacity. By estimating AMR prevalence worldwide, our approach allows for a data-driven prioritization of surveillance efforts. For carbapenem-resistant Acinetobacter baumannii and third-generation cephalosporin-resistant Escherichia coli, specific countries of interest are located in the Middle East, based on the magnitude of estimates; sub-Saharan Africa, based on the relative prevalence increase over 1998 to 2017; and the Pacific Islands, based on improving overall model coverage and performance.
