Is Marriage the Strongest Predictor of Wealth in Canada?

Love, they say, is a many-splendored thing. But I can tell you with confidence that, in Canada at least, it also pays handsomely.

Sharp downward trends in fertility rates are pointing to a bleak future. And as we’re discovering, immigration isn’t necessarily going to save us. Working on the reasonable assumption that the high costs of raising kids were holding us back, governments have been working for decades to encourage childbirth through programs like the Canada Child Tax Benefit. Their hearts were in the right place, but the result haven’t been great.

The child and family support programs have been significant. For example, the average total of government support transfers in inflation-adjusted dollars paid to single parents have grown from $11,600 in 1976 to $19,400 in 2022. That amounts to around 29 percent of their average total earned income. Benefits for couples with children nearly tripled from a 1976 average of $5,800 to $15,300 by 2022. Those transfers included child benefits, employment insurance benefits, and social assistance.

But it turns out that even without government programs, marriage and parenting are both financially rewarding endeavors. In 2022, According to Statistics Canada, the average individual “not in an economic family” earned just $53,400 from both market (i.e., earned) income and government support. That same year, couples earned $135,600 - an increase of around 51 percent over what they would have earned in 1976. And the average couple with children took $169,900 home. For comparison, single parents earned just $80,100.

Of course it’s possible that couples who happen to be wealthier are more likely consider themselves capable of raising children, so to some extent they’re self-selecting. And some singles feel unable to start families because of crazy housing costs. Nevertheless, it seems that marriage and, to a lesser degree, parenthood are important predictors of higher income.

Are government social support programs behind the imbalance? Not so much. The average couple in 2022 received $7,300 in benefits, but that’s significantly less than the $9,800 that the average singles (without kids) got. In fact, it’s also a lot less than the $10,400 childless couples would have received from the government in 1976.

It’s clearly earned income that’s driving the greater wealth of both couples as a whole and couples with children.

This isn’t a new development. Throughout the half century since 1976 - when you exclude government benefits - couples have out-earned singles by an average of 140 percent. And couples with children have earned an average of 12.5 percent more than couples in general.

The bottom line is that couples - both with and without children - earn significantly more than both single parents and singles living outside of a family unit. This economic reality has persisted through financial crises, evolving government policy standards, and social upheavals.

That knowledge could play a role in young peoples’ thinking as they plan their lives. But it’s also one of many reasons that we, as a society, should aggressively protect the integrity of the family as an institution. All things being equal, families lead to better outcomes.

This idea is something found in no less a source than the United Nation’s Universal Declaration of Human Rights (Article 16):
