I don't know about china, but India is so conservative that it's pretty close to 0, but also probably very hard to get any reliable statistics

There's a bunch of other developing countries missing too, such as the entirety of Africa. Aside from their large populations, I'm not sure why the absence of China and India should be any more surprising than the presence of Colombia and Chile (for example).

It is a bit of a funny mix, though, which makes me wonder of the person who made it was trying to push a narrative.

I think many children born outside marriage are still born inside a permanent relationship. In many countries it isn't normative anymore to marry when you are living together as a couple.

I'm just spit balling here but I believe Catholics are also very against birth control and abortion, so that could play a role as well, no?

More religious means less sex education and less access to birth control. Abortion might also be more frowned upon so they carry the baby to term even out of wedlock. And let’s face it, religion isn’t stopping teenagers with raging hormones and young adults from having sex.

There's also the issue of what "marriage" is defined as in each country. I know that there are states in the US where you qualify as "common law" married if you just live together, both agree you are married, and say in public that you are married. Even stranger is while that sounds a like a liberal thing, it's not. It's the law in at least one of the most conservative states in the US.

A lot of people just don’t get married, or do so very late. I bet the vast majority of those babies are born into healthy long-term relationships.

What is CR?
