What are the differences between World Cities and World Major Cities database? Despite the differences in the database fields, the main differences between them lie in the cities information. World Cities Database comprises the list of all worldwide cities whereas World Major Cities Database only contains those highly populated cities. In other words, World Major Cities is actually a subset of the World Cities Database. If you are going to use the data for general or commercial purposes, such as the dropdown list of country-region for client selection, World Major Cities would be the recommended one.
