Women is working harder than men?

When I was waiting for the nightly bus at last night, I notice a strange thing.

At the bus station, there is 7 women and 3 men.

In the passing buses, more women than men in the first impression.

When I took my bus, I also found that the scale of women and men was about 3:1.

When I took my lift, I found that there is 3 girls arround me, and I am the only boy.

Is women working harder than men in this city?
