Why Have Interracial Marriages Shot Up Since 1997?

For indispensable reporting on the coronavirus crisis, the election, and more, subscribe to the Mother Jones Daily newsletter.

Alex Tabarrok pointed today to a paper that caught my eye. In it, the authors offer an explanation for why interracial marriages, which had been increasing at a steady rate for decades, suddenly accelerated in the mid-90s. Their answer: the rise of online dating played a big role.

The reasons for this are a little complicated, and you can read the paper if you’re interested. However, here’s the basic chart that motivates the analysis. It shows the percentage of interracial marriages among newlyweds:

This is interesting, and I don’t really have any special reason to doubt the online-dating hypothesis. But there’s an odd thing: the trendline accelerates first in the mid-90s, and then accelerates again around 2007. (The red line is my eyeball trendline.) So does that mean online dating also accelerated in 2007? It turns out the answer is no:

At the very moment that online dating plateaued among hetero couples, the growth rate of interracial marriages took a big jump, from 0.35 percent per year to 0.58 percent per year. This doesn’t fit the online-dating model.

So either it’s wrong or it’s incomplete. If it’s incomplete, it means something happened around 2007 in addition to online dating that caused a big jump in the number of interracial marriages. What do you suppose it could be? An Obama effect? A Facebook effect? Something else?

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
