All-the-cities is a comprehensive JSON dataset containing 138,398 cities worldwide with populations of at least 1,000 inhabitants, designed for easy import into MongoDB for geospatial searches. It provides detailed information for each city including geographic coordinates, population data, and administrative codes, making it an ideal resource for developers building location-based applications or conducting geographic analysis. The project is particularly useful for developers working with Node.js who need a ready-to-use, structured dataset of global cities.
