Begin by typing in any 50K+ world city in the format City, Country – i.e. ‘Moscow, Russia’. Use ‘Bosnia’ for Bosnia & Herz, ‘Czech’ for Czech Republic, ‘CAR’ for Central Afr Republic, ‘DRC’ for Dem Rep of the Congo, ‘UK’ for United Kingdom, ‘UAE’ for United Arab Emirates, and ‘US’ for United States. There are a handful of cities with the same name in the same country. For those in the US, add the state in the format ‘City, State, US’ – i.e. ‘Aurora, CO, US’ – for other countries, add a number corresponding to the population rank for that city among similar-named cities in that country, i.e. for the largest Fuzhou, China, type ‘Fuzhou, China1’. Then name the 250 closest cities to the one you chose.
