It should be around 2000! Mayors should range from 5,000 to 6,000, district heads from 3,500 to 5,000, street office directors and township heads from around 3,000, and clerks from 1000 to over 2,000, with a few below 1000, so the average number should be around 2,000! Be a civil servant if you have the chance! Better than anything, there is no risk but happiness! Good luck!
