For 63 straight years, the number of boys born in he United States has outnumbered the births of girls, according to a June 14, 2005, news release from the Centers for Disease Control and Prevention (CDC). A report from the CDC examines total gender ratios at birth (ie, number of male births divided by female births times 1,000) for more than six decades.

Findings of the report include the following.

* Between 1940 and 2002, an average of 91,685 more male babies than female babies have been born each year, a total of 5,776,130 during that 63-year period.

* The highest ratio occurred in 1946 (ie, 1,059 mate births per 1,000 female births), and the lowest occurred in 1991 and 2001 (ie, 1,046 male births per 1,000 female births).

* The more children a woman has the more Likely she is to give birth to an equal number of boys and gifts.
