I went to the BLS website and looked up the occupational statistics on agriculture and construction. From these statistics I extrapolated the contribution by sex via the number of people employed in that industry.
The next time you sit down to a meal, or close the door behind you to keep out the bad weather consider the following:
Men produce 78% of the food we eat.Men build 97% of our structures (houses, apartments, offices, stores, roads...)
