Same Sex Couples - 7 times less likely to have children in 2017 than Heterosexual Couples

Been looking through the IVF stats and pondered if we could use those stats to detect Gay and Lesbian Birth ratios. As Same sex couples absolutely have to use IVF treatments (Surrogacy in the case of Males and Sperm Donation in the case of females) to reproduce, we can extrapolate those figures to see what the interest is in having kids in the homosexual community.

Anyway, we first have to start with the estimates of the couples. In 2016, there were 46,800 same sex couples, 50.6% male, 49.4% female. The same sex couple rate had been growing at 6.8% a year since 2011. So extrapolating that into 2017, it leads us to 49,977 same sex couples in 2017.

In regards to total couples, in 2016, there were 5,200,000 couples in Australia (removing the same sex couples gives us 5,153,200), and that was growing at 1.5% a year.
So extrapolating that into 2017, it leads us to  5231138 hetero-sexual couples in Australia,

Now we have the births. Assuming all Surrogacy live births are Gay Couple babies (likely to produce a higher number), we have 62 babies born in 2017

Assuming all Sperm donor babies are Lesbian Couple babies (again, too high) we have 348 live births. So that gives us a total of 410 babies for Same Sex Couples.

The total live births are 309,142 births. Take away the 410 same sex couple babies and we have 308,732

So the rate of Hetero sexual couple to live birth is (5231138/308732) =16.94

Rate of Homosexual couple to live birth is (49,977/410) = 121.9

So Heterosexual couples are 7.2 times more likely to have a child in 2017 that Homosexual Couples.

If you divide the stats into Male Couples vs Female Couples

Males Couples  are 24 less likely to have kids than Heterosexual Couples
Female Couples are 4 times less likely to have kids than Heterosexual Couples.

Makes you wonder why the Same Sex marriage debate was so toxic. Same Sex couples are less likely to want kids anyway.
