As you age, the number of pushups you are able to do might diminish. Your pushup endurance is also determined by gender. The norms state that males should be able to do more pushups than females. However, this changes depending on personal fitness levels. In any case, you can improve your pushup count over time.
Average Pushups for Females
The average number of pushups a female is able to perform depends on their age. The American College of Sports Medicine batches females, as well as males, into groups that are determined by their age. A female that ranges from the age of 20 to 29, 30 to 39, 40 to 49, 50 to 59 and 60+ should be able to perform 17 to 33, 12 to 24, 8 to 19, 6 to 14 and 3 to 4 pushups in their respective order. An important note for female pushup tests is that they are based on the modified pushup. The modified pushup is done on the knees rather than on the toes.
Average Pushups for Males
Age plays an important factor in the average number of pushups a male could do as well. A male that ranges from the age of 20 to 29, 30 to 39, 40 to 49, 50 to 59 and 60+ should be able to perform 35 to 44, 24 to 34, 20 to 29, 15 to 24 and 10 to 19 pushups respectively. The pushup test for males is based on the standard pushup. The standard pushup is done on the toes, rather than on the knees.
The Pushup Test
The pushup test measures muscular endurance. Muscular endurance is the ability of a muscle to perform over a period of time. Some of the muscles that it tests include the pectoralis major, triceps and anterior deltoids. As previously stated, females perform the pushups from a bent knee rather than doing a standard pushup. The test begins when you begin doing pushups and continues until you're unable to perform anymore or you have bad form.

The number of pushups can increase or decrease greatly based on your fitness level. If you are below these average numbers, don't be alarmed -- because you can improve. The best way to avoid being below average is to do pushups, and other exercises that work your chest muscles. Some exercises that work the chest include bench press, incline press, dumbbell press, and decline press. As you improve on these exercises, you will also improve the number of pushups you can do.
