This study is from the American College of Pediatricians.

The Stream writes about the study:

The American College of Pediatricians recently published a paper, Cohabitation, which cautions adolescents and young adults about the negative consequences of cohabitation for both themselves and their children, and urges parents to teach their children about the advantages of waiting until marriage.

More young people are now first cohabiting than are marrying without prior cohabitation, yet research shows that, rather than being a stepping-stone to a healthy marriage, living together before marriage (cohabitation) makes couples more likely to break-up and more likely to divorce if they do marry. It results in lower marital satisfaction and increased negative communication.  Cohabiting couples spend less time together; men are more likely to spend their time on personal pleasure than do married men.

Commitment failure:

Cohabiting couples are now less likely to later marry than 40 years ago. Controlling for other factors that increase risk of divorce, marriages preceded by cohabitation are still 50 percent more likely to end in divorce.  (Some recent studies challenge this, but are scientifically flawed and omit the raw data.)  Also 27 percent of cohabitations dissolve without marriage in the first three years.

Domestic violence:

Cohabiters commit increased violence against their partner. Women are nine times more likely to be killed by a cohabiting partner than by their husband. Severe violence is four times as common among cohabiting couples; any violence is nearly 50 percent more common among couples cohabiting before marrying and doubled among couples continuing to cohabit after five years.

Alcohol abuse:

Men who cohabit without marrying in 5 to 10 years have more than double the rate of alcohol abuse as married men; women who cohabit without marrying have 4 to 7 times the rate of alcohol abuse as married women.

Infidelity:

Cohabiters, both men and women, have rates of infidelity in the preceding year more than triple that of married spouses. Among the married, those cohabiting prior to marriage were 50 percent more likely to be unfaithful as those marrying without cohabiting.

Poverty:

Poverty is more common among cohabitating women and their children. Their male partners have both a higher unemployment rate (15 percent vs 8 percent), and work less hours if employed.

Abortion:

Cohabitating women are ten times more likely to have an abortion than married women, and suffer from its associated mortality and morbidity. In fact, 89 percent of women who have had abortions have at one time cohabited; 40 percent have lived with three or more men. Abortion also puts future children at risk, especially from extremely premature birth.

Harm to children:

Children who survive also suffer due to parental cohabitation.  They have increased risk of losing a parent to divorce or separation, possibly multiple times.  Children born of cohabiting parents are over four times more likely to suffer separation of their parents by their third birthdays (49 percent) than those born to married parents (11 percent).

[…]Nearly one-third of couples enter into cohabitation with a child from a previous relationship, as do half of those cohabitating for six years or longer. Children living with a parent and unmarried partner (live-in boyfriend) have 20 times the risk of sexual abuse and eight times the risk of all maltreatment compared to children living with married biological parents.  Even if the couple marries, stepchildren have over eight times the risk of sexual abuse and triple the overall risk of abuse of neglect. Girls living with a stepparent had 60 percent higher risk of being raped than girls living with their biological parents.

Depression:

Women in cohabiting relationships have more depression than married women, and poorer responsiveness to their children’s emotional needs.  Children whose mothers are depressed have increased cortisol responses to stress (which may explain their increased hypertension in adulthood). Children with unmarried mothers are half as likely to be breastfed, leading to higher rates of asthma, pneumonia, ear and intestinal infections, diabetes, obesity, and lower intelligence.

So what do I want to say about this in my 500 words? Well, I want to say that the cohabitation issue is a good opportunity for us to reason about whether there should be any rules around sexuality and relationships.

Our culture is absolutely poisoned right now with a kind of feelings-oriented non-judgmentalism that prevents debate. Everything has been reduced to people feeling “offended” and using the power of government to stifle debate. Nowhere is this more evident than on the university campus, which is the source of the problem. This hyper-tolerance and emotional non-judgmentalism leaves people open to making poor decisions that cause self-destruction and harm to others. As a result, young people are blindly accepting a script for sexuality and relationships from the culture, e.g. – Hollywood, celebrities, and ideologically-driven academics. A script made by professional story-tellers insulated from the consequences of their ideas.

As Christians, we seem to have so much trouble talking to young people about rules around sexuality and relationships. So many young people think that premarital sex is benign. That cohabitation is no big deal. And that redefining marriage cannot be opposed. Christian parents and pastors are not preparing themselves to discuss these things with young people. If there is a battle of ideas, and one side shows up with a bunch of feelings and lies, that side still wins – if the other side doesn’t show up at all. Don’t be so focused on your career and your own self that you fail your children by failing to discuss and debate with them about the issues. Don’t assume that just because your children look OK on the surface that there are not serious questions underneath.

There is so much I could say about this problem of talking to young people. As I argued in a previous post, I truly believe that apologists should not neglect these social / cultural / fiscal issues. We have to study them and know how to argue for our values using secular arguments and evidence, such as you see in the study above. Once young people have decided that Christian teachings on sexuality (e.g. – chastity, courting) are primitive and irrational, or worse, then getting them to accept Christianity becomes that much harder. And that goes double for marriage. If they think that cohabitation, no-fault divorce, same-sex marriage and gay adoption are opposed for no other reason than blind prejudice or even hatred, then we’ve lost before we even begin to make our first philosophical argument. We have to use a combined arms approach.

Let’s attack! Now is the time!
