How do you calculate Global Did You Feel It in countries where there are no Zip Codes?

We have recently expanded Did You Feel It? to a global scale. Users from all over the world can now contribute their earthquake experiences. Since zip codes do not exist or are not available in most countries, we have simplified the system to base location on the approximate latitude and longitude of the city which the respondent was closest to. On the map, it is displayed as a filled circle, the size of which is dependent on the population of the city. Since we need to know the city's location to map it, only cities in our database can be selected by observers.
