Hello Sir
There is 64 city in the USA, which has 9800 to 10200. But I'm not sure if you will count this Population as you have just asked for 10K Population.
I have the data as
city, city_ascii, state_id, state_name, county_fips, county_name, lat, lng, population, population_proper, density, timezone, zips,
Kindly send me a message to attach the sample data in excel file.
