In the given case, the percent of total driver under the age of 20 are (9435/92290)*100 = 10.22%.
The percent of total male drivers are = (46021/92290)*100 = 49.87%.
Here it can be observed that the female drivers are greater in number between the age group of 20 to 59, while the male drivers are more in numbers for the individuals below the age 20 and above the age 60.
