The three key areas of family economics—marriage, child-rearing, and divorce—are explained by describing price inflation variables from across the globe. Rising prices for educational goods and services, housing, and other relevant household costs have contributed to later ages for first marriage throughout the world. Furthermore, fertility reductions have been linked to rising housing costs, increased time preference rates, net income flows for having children as well as governmental interventions of various kinds. Divorce is the least understood phenomenon among economists, nevertheless, strained household finances, changing labor market dynamics and real income and wealth, have all been pointed out as contributing to divorce trends in the post-World War II era. Monetary inflationism is a neglected variable that may play a role in generating these family-altering phenomena.
