Despite the number of single fathers doubling in the last 25 years - from 4% to 8%, there are almost no studies on single fathers. By single father - it is a man who has primary custody, in most cases the biological mother just has visitation rights. It isn't evident from google but these single fathers almost never receive child support or government help.

So google single parent assistance - it almost always changes to single mother assistance - a blight on society. That single mothers are a blight on society is rationalized away by these studies.

There are twice as many Single fathers as LGBTQ but they don't get a special day etc. Just saying.
