I just want to breakdown a bit further the statistics.
First of all, the calculations in this summary is based on (12 months basic + all bonus) / 12 which means if consider AWS + 2 months average salary, you should be earning 12.5k/month in this summary table. For easy calculations, we can used above $12k/month

Age 25 to 29 around 3.1k which means 620/45,200 = 1.4% at each age earns above $10k/month
Age 30 to 34 around 16.5k which means 3,300/47,400 = 7.0% at each age earns above $10k/month
Age 35 to 39 around 34.5k which means 6,900/50,060 = 13.8% at each age earns above $10k/month

Age 25 to 29 around 1.6k which means 320/45,200 = 0.7% at each age earns above $12k/month
Age 30 to 34 around 10.0k which means 2,000/47,400 = 4.2% at each age earns above $12k/month
Age 35 to 39 around 21.8k which means 4,360/50,060 = 8.7% at each age earns above $12k/month
