It’s well known that in the US/West women initiate 70-80% of divorces, I was curious to see if this was uniquely a western phenomenon or not, so I did some digging. I came across an interesting article about divorce in China which had this stat:

Around 74 percent of first hearings in divorce cases in 2016 and 2017 were filed by women, according to a report by China's Supreme People's Court.

Doing some more digging, I found stats from other countries showing similar numbers, with 70-80% of divorces being filed by women.

A stat from Poland:

Constantly in over 2/3 of all cases, it was women who filed for a divorce.

Singapore:

In 2012, 64% of the divorce cases were initiated by women, filing.

Iran:

Most divorces take place during the first two years of marriage and are initiated by women.

Brazil:

The lawyer says that about 70% of divorce applications are initiated by women, and the most frequent complaint is the work overload they have.

Indonesia:

Currently, more than 70% of divorce cases decided by Indonesia’s Islamic courts are initiated by wives.

Morocco:

Moreover, while over 14,000 divorce proceedings were initiated by men, over 26,000 were initiated by women in 2007;

That adds up to women initiating at least 65% of divorce proceedings in Morocco.

Anyways, I think you guys get the point. While this not every country, it does point to an interesting trend where the majority of divorces across different cultures are filed by women, this does not seem to be a western only phenomenon. So far in my research (and I’ve looked at a lot more countries then what I listed) I have not been able to find one country where men are the ones who file the majority of divorces. Why do you think that is? Any theories as to why women regardless where they are from are more likely to end a relationship/marriage?
