Why would females have the higher population in the younger age groups (0-4 yrs.)? Does it have something to do with a biological advantage during conception?

Thanks.

Assuming that statistic to be true (I haven't checked), I do recall hearing that the risk of SIDS (sudden infant death syndrome) is higher for males than for females. The cause of SIDS is unknown. Not to say that SIDS is the only reason, but it may be one factor.
