As cohabitation has gone from a pre marriage detour to a full on highway worldwide, the UN’s birth outside marriage trend has climbed while numerous U.S., Nordic, and European studies keep finding that unions begun by cohabiting are typically far more likely to break up and end in divorce than marriages, with children and relationship stability paying a noticeable price for that “try before you tie the knot” gamble.

Single sourceLegal & Economic Consequences Interpretation
In the U.S., cohabiting may look like marriage at Netflix volume, but legally it’s often a low-security contract with looser protections, worse tax and benefit treatment, and thinner intestate and property rights that help explain why cohabiting households with children can be far more likely to live in poverty than their married-couple counterparts.
