Consider using offline geocoder

[prusnak]

Such as https://github.com/lucaspiller/offline-geocoder

the code above builds the data from:

• cities above 1000 ppl: http://download.geonames.org/export/dump/cities1000.zip (~8MB compressed)
• administrative units: http://download.geonames.org/export/dump/admin1CodesASCII.txt
• countries: http://download.geonames.org/export/dump/countryInfo.txt

we can easily build our own dataset from these, for example:

city, administrative unit, country, population

and sort the returned answers by population
