In 2001, 1.35 million children were born outside marriage. This represents 33.5 percent of all children born in the United States in that year. Children raised by never-married mothers are seven times more likely to be poor when compared to children raised in intact married families. The obvious nexus between single-parent families and child poverty has led President George W. Bush to propose a new trial program aimed at increasing child well-being and reducing child poverty by promoting healthy marriage.
Critics have rejected President Bush’s proposal as illogical. They argue that increasing marriage would not significantly reduce child poverty for two reasons: first, that there is a substantial shortage of suitable males for single mothers to marry, and second, that even if single mothers married the father of their children, the earnings of the fathers are so low that they would not lift the family out of poverty.
However, new light has been shed on the status of non-married parents though the recent Fragile Families and Child Well-Being Study. The Fragile Families survey is a nationwide effort to collect data on both married and non-married parents at the time of a child’s birth. The survey reveals that most of the claims about marriage and non-married fathers made by the opponents of the Bush “healthy marriage” proposal are wildly inaccurate.
The Fragile Families Study shows the following:
- The median age of non-married mothers is 22 at the time of birth of the child.
- Nearly three-quarters of non-married mothers are in a relatively stable romantic relationship with the expectant father at around the time of birth of their child.
- The expectant non-married fathers who have a romantic involvement with the mother-to-be are quite “marriageable.” Very few have drug, alcohol, or physical abuse problems.
- On average, the earnings of non-married expectant fathers are higher than the earnings of expectant mothers in the year before the child’s birth.
- The median annual earnings of non-married fathers are approximately $17,500 per year.
In this CDA Report, the Fragile Families data are used to calculate how much marriage could reduce poverty among couples who are not married at the time of the child’s birth. This analysis finds that marriage would dramatically reduce poverty among the non-married mothers who are romantically involved with the fathers at the time of the child’s birth.
Specifically, if these mothers do not marry but remain single, about 55 percent will be poor. By contrast, if all the mothers married the child’s father, the poverty rate would fall to less than 17 percent. Thus, on average, marriage would reduce the odds that a mother and a child will live in poverty by more than 70 percent.
The contention, made by critics of the President’s marriage-strengthening policy, that increased marriage will not reduce child poverty because fathers do not earn enough to lift a family out of poverty is inaccurate. While marriage of mothers and fathers would not eliminate child poverty in every case, in the overwhelming majority of cases, marriage would lift families out of poverty. Overall, the insights culled from the Fragile Families dataset and described in this CDA Report strongly indicate that a policy aimed at promoting healthy marriage among young parents has enormous potential to reduce child poverty.
Analysis
The data used in this analysis are taken from the Fragile Families and Child Well-Being Study, developed jointly by Princeton University’s Center for Research on Child Well-Being and Columbia University’s Social Indicators Survey Center. The Fragile Families Study provides the best data available on the characteristics of non-married parents around the time of a child’s birth.
These couples are of particular public policy interest since they are likely to be a high-priority target group for President Bush’s proposed program to promote healthy marriage. Thus, the non-married parents in the Fragile Families survey are an excellent population for assessing the potential economic consequences of increasing marriage.
Characteristics of Non-Married Parents
Some 38 percent of the mothers in the Fragile Families Study were not married at the time of their child’s birth. Popular opinion sees out-of-wedlock childbearing as occurring mainly to young girls of high-school age who lack stable relationships with their child’s father. This perception is erroneous. The median age for mothers who give birth outside marriage is 22.
Nor are non-married mothers alone and isolated at the time of birth. As Table 1 shows, nearly 50 percent of these mothers are cohabiting with the expectant father at around the time of the child’s birth. Another 23 percent describe themselves as “romantically involved” with the father, although the couple is not cohabiting.

The characteristics of non-married fathers who are cohabiting or romantically involved with the mother are generally more favorable than the popular stereotype. (See Table 2.) Around 67 percent of the fathers have at least a high-school degree. Some 97 percent were employed during the prior year, and 82 percent were employed at the time of the child’s birth. The median annual income of these romantically involved/cohabiting fathers was between $15,000 and $20,000.
Among romantically involved or cohabiting couples, physical abuse is rare: A full 98 percent of the women in this group report that the father has never slapped them when angry. While some fathers do have drug and alcohol problems, the level is less than might be expected: Around 12 percent of the mothers report arguing with their boyfriends about a drug or alcohol problem in the last month; 2.5 percent report that drugs or alcohol impede the boyfriend’s ability to hold a job.

On average, the non-married expectant fathers have higher earnings than the expectant mothers in the year before the child’s birth. The median wage rate of fathers is $8.55 per hour, compared to $7.00 per hour for the mothers.
Nearly all couples that are romantically involved or cohabiting are interested in developing a long-term, stable relationship. Some 95 percent believe that there is at least a 50/50 chance they will marry in the future.
Marriage Simulation
The purpose of this CDA Report is to calculate the reduction in poverty that would occur if non-married women married the fathers of their new children around the time of the child’s birth. As shown in Table 1, some non-married pregnant women do not have positive and stable relationships with their child’s father. In these cases, marriage is not, for the most part, a reasonable option. Therefore, we have restricted our initial marriage simulation to the 73 percent of non-married couples who were cohabiting or romantically involved but living apart at the time of their child’s birth. We shall henceforth refer to these couples as the “marriageable group.”
To determine the impact of marriage on the poverty of children and mothers, we first estimate what the poverty rate of the mothers would be if they remained single. We then calculate what the poverty rate would be if the mother and father marry. The difference between the poverty rate of the mothers when single and the rate for mothers when married demonstrates the potential for marriage to reduce child poverty and maternal poverty.
Employment and Earnings
The Fragile Families survey contains data on the annual earnings of new fathers during the year in which the child was born. We employ these annual earnings figures in our analysis. The study also provides annual earnings for mothers in the year before birth. However, women’s participation in the labor force may be altered significantly by the birth of a child. Because of this, the paper estimates mothers’ post-birth earnings based on a range of assumptions concerning the hours of employment.
Specifically, we have calculated the effect of marriage on poverty according to three separate scenarios relating to the mothers’ employment after the child’s birth.
In each scenario, the annual earnings of the fathers are assumed to be the same as the earnings in the year before the child’s birth. The annual earnings of the mother are derived by multiplying the mother’s hourly wage rate by the specified hours worked. In each scenario, the employment and earnings of a mother are assumed to be unchanged by marriage; that is, the mother is assumed to earn the same amount when married as when single.
Welfare Benefits
The simulation assumes that single mothers will be eligible for TANF (Temporary Assistance for Needy Families), EITC (Earned Income Tax Credit), and food stamps. The level of benefits that a single mother would receive from each program is determined by the number of children in the family and the mother’s annual earnings. Simulations for married couples assume that they are eligible only for food stamps and the EITC. The couple’s earnings and family size determine the value of benefits. It is assumed that no married couples will receive TANF benefits.
Results of the Marriage Simulation
Under each scenario, we calculate the percentage of mothers who would be poor if they lived as single parents and the percentage who would be poor if they were married to the child’s father.
Scenario #1: The mother is unemployed
Chart 1 shows the impact of marriage on maternal and child poverty under Scenario #1. In this scenario, the mothers are not employed after the birth of the child. When single, the mothers are solely dependent on welfare (TANF and food stamps). When married, the mothers are solely dependent on the father’s earnings plus EITC and food stamps.

As Chart 1 shows, if mothers remain single and unemployed, they will be poor 100 percent of the time. This is because welfare benefits alone rarely, if ever, provide enough income to raise a family above the poverty level. By contrast, if the mother marries the child’s father, the poverty rate drops dramatically to 35 percent. In other words, nearly two-thirds of the non-married fathers within the marriageable group earn enough by themselves to support a family above poverty without any employment on the part of the mother.
Under the conditions of Scenario #1, marriage more than doubles the family income of mothers and children. If unmarried, the mothers would have a median income of around $8,800. Marriage would raise the mothers’ median family income by over $11,000 to $20,226. (See Table 3.)
Scenario #2: The mother is employed part-time
Chart 2 shows the impact of marriage on child poverty under Scenario #2. In this scenario, mothers are assumed to be employed part-time for a total of 1,000 hours per year after the birth of their child. This scenario closely matches the employment rates of single mothers with young children as reported by the U.S. Bureau of the Census. Thus, it is the most realistic of the three scenarios.
Single mothers are assumed to receive income from earnings, EITC, food stamps, and, in some cases, TANF. Married couples are assumed to receive income from earnings, EITC, and food stamps. In this scenario, mothers are assumed to work 1,000 hours per year, whether single or married.
As Chart 2 shows, 55 percent of the mothers in the Fragile Families Study will live in poverty if they remain single and are employed part-time. By contrast, if the mothers marry, their poverty rate plummets to 17 percent. In other words, the father’s normal earnings, combined with the part-time earnings of the mother, are sufficient to raise 83 percent of the families above the poverty line.
Under conditions of part-time maternal employment in Scenario #2, marriage increases family income by 75 percent. If unmarried, mothers would have a median income of around $13,500. Marriage would raise the mothers’ median family income by around $10,000 to a level of $23,700.
Marriage combined with part-time maternal employment not only raises nearly all families above poverty, but in many cases also raises family income well above the poverty level. For example, under Scenario #2, less than 4 percent of single mothers would have family incomes above 150 percent of the poverty level. By contrast, about 46 percent of married couples would have an income above 150 percent of the poverty level.
Scenario #3: The mother is employed full-time
Full-time/full-year employment is very effective in reducing poverty among single mothers. Some 90 percent of single mothers could maintain their families above poverty if they worked full-time throughout the year. (Full-time/full-year employment is equivalent 2,000 annual hours of employment or 40 hours per week for 50 weeks.) Census Bureau data reveal that approximately 30 percent of single mothers with children under four are employed 2,000 hours or more per year.
Since very few single mothers who were employed full-time/full-year would remain poor, marriage has little effect in reducing poverty in this scenario. (Nearly 96 percent of married couples would have incomes above the poverty level, compared to 90 percent of single mothers.) However, marriage would raise the family incomes of many full-time working mothers well above poverty and into middle-class levels.
Full-time working mothers would have a median income of around $17,500 per year. If these mothers married their child’s father, median family income would rise to $29,000 per year. As Chart 4 shows, nearly two-thirds of these married couples would have incomes above 150 percent of the poverty level. By contrast, only 20 percent of full-time working single mothers would have incomes above that level.

Summary of Results
Tables 3 and 4 summarize the results of the three scenarios for marriageable couples. As Table 3 shows, marriage would increase median family income of mothers in the study by between $10,200 and $11,400 per year. (The increase in median family income is less than the median annual earnings of the fathers—$17,500—because marriage entails an offsetting loss of welfare benefits for the mother.)
Table 4 summarizes the impact of marriage on poverty. In each scenario, marriage reduces the probability that mothers will live in poverty by at least two-thirds. Marriage would lift the incomes of many mothers above 150 percent of the poverty level. In Scenario #1, some 30 percent of married families would have incomes above 150 percent of the poverty level. In Scenario #3, nearly two-thirds of married families would have incomes above that level.


Alternative Marriage Simulation for All Non-married Couples
As noted, the marriage simulation data presented in Charts 1, 2, and 3 and Tables 3 and 4 pertain to the “marriageable” couples within the Fragile Families survey—i.e., those who, at the time of the child’s birth, are cohabiting or living separately but are still romantically involved. These couples represent 73 percent of all non-married couples at the time of a child’s birth.
Expectant mothers and fathers in the marriageable group have somewhat higher earnings than other non-married couples in the year before their child’s birth. Therefore, marriage may have a substantially greater effect in reducing poverty among the marriageable group than among non-married couples in general.
To investigate that possibility, the marriage simulation was rerun for all non-married couples in the Fragile Families survey; thus, the new simulation included both the “marriageable” and “non-marriageable” couples. The results of this expanded simulation were extremely similar to those for the marriageable subset. For example, under Scenario #2, 56.5 percent of mothers will be poor, if unmarried, compared to 18.4 percent of mothers, if married. (For the marriageable sub-group, the figures were 55.1 percent and 16.9 percent, respectively.) The complete results of the expanded simulation for all non-married couples are shown in Appendix Table A.
