male to female ratio of total US population: 0.97
male to female ratio at birth in US: 1.05
No offense, but rowdyowl's answer simply isn't right. I think he is just using general reasoning without having the data or technical biological information to reach the correct conclusion.

It depends on how you count: There are about 105 males born for every 100 females born.
However, more males die at a young age than do females, so the ratio evens out if you count adult population. There are tyically more females alive than males unless there is significant cultural pressure against having females (as there still is in some backwards cultures.)

Pretty much any population that is large enough and has no strange influences is going to be almost exactly 1:1. Sex chromosomes and the laws of random assortment ensure it.
actuator is right, but it is interesting to see how the current birth rate seems to compensate for the current imbalance. It's be fascinating to see those statistics over time and see if there is constant pattern fluctuating above and below 1.00
