In 1966, one year after Nicolae Ceausescu became the Communist dictator of Romania, he made abortion illegal. "The fetus is the property of the entire society," he proclaimed. "Anyone who avoids having children is a deserter who abandons the laws of national continuity."

Such grandiose declarations were commonplace during Ceausescu's reign, for his master plan-to create a nation worthy of the New Socialist Man-was an exercise in grandiosity. He built palaces for himself while alternately brutalizing and neglecting his citizens.
Abandoning agriculture in favor of manufacturing, he forced many of the nation's rural dwellers into unheated apartment buildings. He gave government positions to forty family members including his wife, Elena, who required 40 homes and a commensurate supply of fur and jewels. Madame Ceausescu, known officially as the Best Mother Romania Could Have, was not particularly maternal. "The worms never get satisfied, regardless of how much food you give them," she said when Romanians complained about the food shortages brought on by her husband's mismanagement. She had her own children bugged to ensure their loyalty.

Ceausescu's ban on abortion was designed to achieve one of his major aims: to rapidly strengthen Romania by boosting its population. Until 1966, Romania had had one of the most liberal abortion policies in the world. Abortion was in fact the main form of birth control, with four abortions for every live birth. Now, virtually overnight, abortion was forbidden. The only exemptions were mothers who already had four children or women with significant standing in the Communist Party. At the same time, all contraception and sex education were banned. Government agents sardonically known as the Menstrual Police regularly rounded up women in their workplaces to administer pregnancy tests. If a woman repeatedly failed to conceive, she was forced to pay a steep "celibacy tax."

Ceausescu's incentives produced the desired effect. Within one year of the abortion ban, the Romanian birth rate had doubled. These babies were born into a country where, unless you belonged to the Ceausescu clan or the Communist elite, life was miserable. But these children would turn out to have particularly miserable lives. Compared to Romanian children born just a year earlier, the cohort of children born after the abortion ban would do worse in every measurable way: They would test lower in school, they would have less success in the labor market, and they would also prove much more likely to become criminals.

The abortion ban stayed in effect until Ceausescu finally lost his grip on Romania. On December 16, 1989, thousands of people took to the streets of Timisoara to protest his corrosive regime. Many of the protestors were teenagers and college students. The police killed dozens of them. One of the opposition leaders, a 41-year-old professor, later said it was his 13-year-old daughter who insisted he attend the protest, despite his fear. "What is most interesting is that we learned not to be afraid from our children," he said. "Most were aged 13 to 20." A few days after the massacre in Timisoara, Ceausescu gave a speech in Bucharest before one hundred thousand people. Again the young people were out in force. They shouted down Ceausescu with cries of "Timisoara!" and "Down with the murderers!" His time had come. He and Elena tried to escape the country with $1 billion, but they were captured, given a crude trial, and, on Christmas Day, executed by firing squad.

Of all the Communist leaders deposed in the years bracketing the collapse of the Soviet Union, only Nicolae Ceausescu met a violent death. It should not be overlooked that his demise was precipitated in large measure by the youth of Romania-a great number of whom, were it not for his abortion ban, would never have been born at all.

The story of abortion in Romania might seem an odd way to begin telling the story of American crime in the 1990s. But it's not. In one important way, the Romanian abortion story is a reverse image of the American crime story. The point of overlap was on that Christmas Day of 1989, when Nicolae Ceausescu learned the hard way-with a bullet to the head-that his abortion ban had much deeper implications than he knew.

On that day, crime was just about at its peak in the United States. In the previous 15 years, violent crime had risen 80 percent. It was crime that led the nightly news and the national conversation.

When the crime rate began falling in the early 1990s, it did so with such speed and suddenness that it surprised everyone. It took some experts many years to even recognize that crime was falling, so confident had they been of its continuing rise. Long after crime had peaked, in fact, some of them continued to predict ever-darker scenarios.

But the evidence was irrefutable: the long and brutal spike in crime was moving in the opposite direction, and it wouldn't stop until the crime rate had fallen back to the levels of 40 years earlier.

Now the experts hustled to explain their faulty forecasting. The criminologist James Alan Fox explained that his warning of a "bloodbath" was in fact an intentional overstatement. "I never said there would be blood flowing in the streets," he said, "but I used strong terms like `bloodbath' to get people's attention. And it did. I don't apologize for using alarmist terms." (If Fox seems to be offering a distinction without a difference-"bloodbath" versus "blood flowing in the streets"-we should remember that even in retreat mode, experts can be self-serving.)

After the relief had settled in, after people remembered how to go about their lives without the pressing fear of crime, there arose a natural question: just where did all those criminals go?

At one level, the answer seemed puzzling. After all, if none of the criminologists, police officials, economists, politicians, or others who traffic in such matters had foreseen the crime decline, how could they suddenly identify its causes?

But this diverse army of experts now marched out a phalanx of hypotheses to explain the drop in crime. A great many newspaper articles would be written on the subject. Their conclusions often hinged on which expert had most recently spoken to which reporter. Here, ranked by frequency of mention, are the crime-drop explanations cited in articles published from 1991 to 2001 in the ten largest-circulation papers in the LexisNexis database:


1. Innovative policing strategies 52
2. Increased reliance on prisons 47
3. Changes in crack and other drug markets 33
4. Aging of the population 32
5. Tougher gun control laws 32
6. Strong economy 28
7. Increased number of police 26
8. All other explanations (increased use of 34 capital punishment, concealed-weapons laws, gun buybacks, and others)

If you are the sort of person who likes guessing games, you may wish to spend the next few moments pondering which of the preceding explanations seem to have merit and which don't. Hint: of the seven major explanations on the list, only three can be shown to have contributed to the drop in crime. The others are, for the most part, figments of someone's imagination, self-interest, or wishful thinking. Further hint: one of the greatest measurable causes of the crime drop does not appear on the list at all, for it didn't receive a single newspaper mention.

Think back for a moment to Romania in 1966. Suddenly and without warning, Nicolae Ceausescu declared abortion illegal. The children born in the wake of the abortion ban were much more likely to become criminals than children born earlier. Why was that? Studies in other parts of Eastern Europe and in Scandinavia from the 1930s through the 1960s reveal a similar trend. In most of these cases, abortion was not forbidden outright, but a woman had to receive permission from a judge in order to obtain one. Researchers found that in the instances where the woman was denied an abortion, she often resented her baby and failed to provide it with a good home. Even when controlling for the income, age, education, and health of the mother, the researchers found that these children too were more likely to become criminals.

The United States, meanwhile, has had a different abortion history than Europe. In the early days of the nation, it was permissible to have an abortion prior to "quickening"-that is, when the first movements of the fetus could be felt, usually around the sixteenth to eighteenth week of pregnancy. In 1828, New York became the first state to restrict abortion; by 1900 it had been made illegal throughout the country. Abortion in the twentieth century was often dangerous and usually expensive. Fewer poor women, therefore, had abortions. They also had less access to birth control. What they did have, accordingly, was a lot more babies.

In the late 1960s, several states began to allow abortion under extreme circumstances: rape, incest, or danger to the mother. By 1970 five states had made abortion entirely legal and broadly available: New York, California, Washington, Alaska, and Hawaii. On January 22, 1973, legalized abortion was suddenly extended to the entire country with the U.S. Supreme Court's ruling in Roe v. Wade. The majority opinion, written by Justice Harry Blackmun, spoke specifically to the would-be mother's predicament:

The detriment that the State would impose upon the pregnant woman by denying this choice altogether is apparent. . . . Maternity, or additional offspring, may force upon the woman a distressful life and future. Psychological harm may be imminent. Mental and physical health may be taxed by child care. There is also the distress, for all concerned, associated with the unwanted child, and there is the problem of bringing a child into a family already unable, psychologically and otherwise, to care for it.

The Supreme Court gave voice to what the mothers in Romania and Scandinavia-and elsewhere-had long known: when a woman does not want to have a child, she usually has good reason. She may be unmarried or in a bad marriage. She may consider herself too poor to raise a child. She may think her life is too unstable or unhappy, or she may think that her drinking or drug use will damage the baby's health. She may believe that she is too young or hasn't yet received enough education. She may want a child badly but in a few years, not now. For any of a hundred reasons, she may feel that she cannot provide a home environment that is conducive to raising a healthy and productive child.

In the first year after Roe v. Wade, some 750,000 women had abortions in the United States (representing one abortion for every four live births). By 1980 the number of abortions reached 1.6 million (one for every 2.25 live births), where it leveled off. In a country of 225 million people, 1.6 million abortions per year-one for every 140 Americans-may not have seemed so dramatic. In the first year after Nicolae Ceausescu's death, when abortion was reinstated in Romania, there was one abortion for every 22 Romanians. But still: 1.6 million American women a year who got pregnant were suddenly not having those babies.

Before Roe v. Wade, it was predominantly the daughters of middle or upper-class families who could arrange and afford a safe illegal abortion. Now, instead of an illegal procedure that might cost $500, any woman could easily obtain an abortion, often for less than $100.

What sort of woman was most likely to take advantage of Roe v. Wade? Very often she was unmarried or in her teens or poor, and sometimes all three. What sort of future might her child have had? One study has shown that the typical child who went unborn in the earliest years of legalized abortion would have been 50 percent more likely than average to live in poverty; he would have also been 60 percent more likely to grow up with just one parent. These two factors-childhood poverty and a single-parent household-are among the strongest predictors that a child will have a criminal future. Growing up in a single-parent home roughly doubles a child's propensity to commit crime. So does having a teenage mother. Another study has shown that low maternal education is the single most powerful factor leading to criminality.

In other words, the very factors that drove millions of American women to have an abortion also seemed to predict that their children, had they been born, would have led unhappy and possibly criminal lives.

To be sure, the legalization of abortion in the United States had myriad consequences. Infanticide fell dramatically. So did shotgun marriages, as well as the number of babies put up for adoption (which has led to the boom in the adoption of foreign babies). Conceptions rose by nearly 30 percent, but births actually fell by 6 percent, indicating that many women were using abortion as a method of birth control, a crude and drastic sort of insurance policy.

Perhaps the most dramatic effect of legalized abortion, however, and one that would take years to reveal itself, was its impact on crime. In the early 1990s, just as the first cohort of children born after Roe v. Wade was hitting its late teen years-the years during which young men enter their criminal prime-the rate of crime began to fall. What this cohort was missing, of course, were the children who stood the greatest chance of becoming criminals. And the crime rate continued to fall as an entire generation came of age minus the children whose mothers had not wanted to bring a child into the world. Legalized abortion led to less unwantedness; unwantedness leads to high crime; legalized abortion, therefore, led to less crime.

This theory is bound to provoke a variety of reactions, ranging from disbelief to revulsion, and a variety of objections, ranging from the quotidian to the moral. The likeliest first objection is the most straightforward one: is the theory true? Perhaps abortion and crime are merely correlated and not causal.

It may be more comforting to believe what the newspapers say, that the drop in crime was due to brilliant policing and clever gun control and a surging economy. We have evolved with a tendency to link causality to things we can touch or feel, not to some distant or difficult phenomenon. We believe especially in near-term causes: a snake bites your friend, he screams with pain, and he dies. The snakebite, you conclude, must have killed him. Most of the time, such a reckoning is correct. But when it comes to cause and effect, there is often a trap in such open-and-shut thinking. We smirk now when we think of ancient cultures that embraced faulty causes-the warriors who believed, for instance, that it was their raping of a virgin that brought them victory on the battlefield. But we too embrace faulty causes, usually at the urging of an expert proclaiming a truth in which he has a vested interest.

How, then, can we tell if the abortion-crime link is a case of causality rather than simply correlation?

One way to test the effect of abortion on crime would be to measure crime data in the five states where abortion was made legal before the Supreme Court extended abortion rights to the rest of the country. In New York, California, Washington, Alaska, and Hawaii, a woman had been able to obtain a legal abortion for at least two years before Roe v. Wade. And indeed, those early-legalizing states saw crime begin to fall earlier than the other 45 states and the District of Columbia. Between 1988 and 1994, violent crime in the early-legalizing states fell 13 percent compared to the other states; between 1994 and 1997, their murder rates fell 23 percent more than those of the other states.

But what if those early legalizers simply got lucky? What else might we look for in the data to establish an abortion-crime link?

One factor to look for would be a correlation between each state's abortion rate and its crime rate. Sure enough, the states with the highest abortion rates in the 1970s experienced the greatest crime drops in the 1990s, while states with low abortion rates experienced smaller crime drops. (This correlation exists even when controlling for a variety of factors that influence crime: a state's level of incarceration, number of police, and its economic situation.) Since 1985, states with high abortion rates have experienced a roughly 30 percent drop in crime relative to low-abortion states. (New York City had high abortion rates and lay within an early-legalizing state, a pair of facts that further dampen the claim that innovative policing caused the crime drop.) Moreover, there was no link between a given state's abortion rate and its crime rate before the late 1980s-when the first cohort affected by legalized abortion was reaching its criminal prime-which is yet another indication that Roe v. Wade was indeed the event that tipped the crime scale.

There are even more correlations, positive and negative, that shore up the abortion-crime link. In states with high abortion rates, the entire decline in crime was among the post-Roe cohort as opposed to older criminals. Also, studies of Australia and Canada have since established a similar link between legalized abortion and crime. And the post-Roe cohort was not only missing thousands of young male criminals but also thousands of single, teenage mothers-for many of the aborted baby girls would have been the children most likely to replicate their own mothers' tendencies.

To discover that abortion was one of the greatest crime-lowering factors in American history is, needless to say, jarring. It feels less Darwinian than Swiftian; it calls to mind a long ago dart attributed to G. K. Chesterton: when there aren't enough hats to go around, the problem isn't solved by lopping off some heads. The crime drop was, in the language of economists, an "unintended benefit" of legalized abortion. But one need not oppose abortion on moral or religious grounds to feel shaken by the notion of a private sadness being converted into a public good.

Indeed, there are plenty of people who consider abortion itself to be a violent crime. One legal scholar called legalized abortion worse than either slavery (since it routinely involves death) or the Holocaust (since the number of post-Roe abortions in the United States, roughly thirty-seven million as of 2004, outnumber the six million Jews killed in Europe). Whether or not one feels so strongly about abortion, it remains a singularly charged issue. Anthony V. Bouza, a former top police official in both the Bronx and Minneapolis, discovered this when he ran for Minnesota governor in 1994. A few years earlier, Bouza had written a book in which he called abortion "arguably the only effective crime-prevention device adopted in this nation since the late 1960s." When Bouza's opinion was publicized just before the election, he fell sharply in the polls. And then he lost.

However a person feels about abortion, a question is likely to come to mind: What are we to make of the trade-off of more abortion for less crime? Is it even possible to put a number on such a complicated transaction?

As it happens, economists have a curious habit of affixing numbers to complicated transactions. Consider the effort to save the northern spotted owl from extinction. One economic study found that in order to protect roughly 5,000 owls, the opportunity costs-that is, the income surrendered by the logging industry and others-would be $46 billion, or just over $9 million per owl. After the Exxon Valdez oil spill in 1989, another study estimated the amount that the typical American household would be willing to pay to avoid another such disaster: $31. An economist can affix a value even to a particular body part. Consider the schedule that the state of Connecticut uses to compensate for work-related injuries.

Now, for the sake of argument, let's ask an outrageous question: what is the relative value between a fetus and a newborn? If faced with the Solomonic task of sacrificing the life of one newborn for an indeterminate number of fetuses, what number might you choose? This is nothing but a thought exercise-obviously there is no right answer-but it may help clarify the impact of abortion on crime.

For a person who is either resolutely pro-life or resolutely pro-choice, this is a simple calculation. The first, believing that life begins at conception, would likely consider the value of a newborn versus the value of a fetus to be 1:1. The second person, believing that a woman's right to an abortion trumps any other factor, would likely argue that no number of fetuses can equal even one newborn.

But let's consider a third person. (If you identify strongly with either person number one or person number two, the following exercise might strike you as offensive, and you may want to skip this paragraph and the next.) This third person does not believe that a fetus is the 1:1 equivalent of a newborn, yet neither does he believe that a fetus has no relative value. Let's say that he is forced, for the sake of argument, to affix a relative value, and he decides that 1 newborn is worth 100 fetuses.

There are roughly 1.5 million abortions in the United States every year. For a person who believes that 1 newborn is worth 100 fetuses, those 1.5 million abortions would translate-dividing 1.5 million by 100-into the equivalent of a loss of 15,000 human lives. Fifteen thousand lives: that happens to be about the same number of people who die in homicides in the United States every year. And it is far more than the number of homicides eliminated each year due to legalized abortion. So even for someone who considers a fetus to be worth only one one-hundredth of a human being, the trade-off between higher abortion and lower crime is, by an economist's reckoning, terribly inefficient.

What the link between abortion and crime does say is this: When the government gives a woman the opportunity to make her own decision about abortion, she generally does a good job of figuring out if she is in a position to raise the baby well. If she decides she can't, she often chooses the abortion.

But once a woman decides she will have her baby, a pressing question arises: what are parents supposed to do once a child is born?
