The proportion is 1:1, because in every birth there's a 50% for each. To convience you:
1/2 of the families have 1 boy.
1/4 have 1 girl + 1 boy.
1/8 have 2 girls + 1 boy.
1/16 have 3 girls + 1 boy.
and so on.
So If N is the number of families, the total number of boys is:
(1/2 + 1/4 + 1/8 + 1/16 ...) N = N
Which is obvious since every familiy has 1 boy.
The total number of girls is:
(1/4 + 2* 1/8 + 3* 1/16 + ) N = N.
