Size and Characteristics of the Unauthorized Migrant Population in the U.S.
III. Unauthorized Migrants: Families and Children
Gender and family composition
Because unauthorized migration is driven primarily by the search for better wages (Kochhar 2005), the undocumented migrant is commonly thought of as a young, male worker usually unaccompanied by a wife or children. In fact, the full portrait of the unauthorized migrant population is more varied. Unauthorized migrants also live as couples (sometimes with a spouse who is a U.S. citizen or legal immigrant), and many of these couples have children. Some children are U.S. citizens and some are unauthorized, and sometimes there are both U.S. citizen and unauthorized children in the same family. There are also hundreds of thousands of single women.
The unauthorized population included about 5.4 million adult males which is a little less than half of the 11.1 million total in the March 2005 estimate. There were more unauthorized adult men than women, with those 5.4 million males accounting for 58% of the 9.3 million unauthorized adults in the March 2005 estimates. (See Figure 6.) Approximately half of the adult men, or 2.4 million, were “solo males,” i.e., in the U.S. without wives or children (Figure 7).
There were approximately 3.9 million adult women in the unauthorized migrant population, representing 42% of the adults in the March 2005 estimate. Among adult women, only one in five, or about 730,000, is “solo”— in the U.S. without a husband or children (Figure 7).
There were 6.6 million unauthorized families in March 2005—defined here as a family unit (or solo individual) in which the head or spouse is unauthorized. Since unauthorized families can include U.S. citizens and legal residents as well as unauthorized migrants, the total number of persons in unauthorized families was 14.6 million, a figure that includes the 11.1 million unauthorized migrants.
A majority of these unauthorized families—3.9 million, or 59%—did not have children (Figure 7). They were made up of single adults, couples, or some other combination of adult relatives. The vast majority of these—about 3.2 million of the families without children—were solo individuals.
Families with children
Unauthorized families with children come in many combinations of legal and illegal statuses, both among the parents and their offspring. Of the 14.6 million people in unauthorized families in the March 2005 estimates, there were approximately 4.9 million children. Of these, about 3.1 million children, or 64% of all the children in unauthorized families, were American citizens because they were born in the United States. About 1.8 million of the children in these families were themselves unauthorized. Thus, children make up 16% of the entire unauthorized population of 11.1 million in the March 2005 estimates. (See Figure 6.)
Out of the total of 6.6 million unauthorized families, a significant share can be classified as being of “mixed status”—in other words, families in which at least one parent is unauthorized and at least one child was born in the United States. There were 1.5 million unauthorized families in which all the children were born in the United States. These families represent about one-quarter of all unauthorized families and more than half of unauthorized families with children. Another 460,000 families, or 7% of unauthorized families, had both U.S. citizen children and children who were unauthorized. Taken together, these mixed status families represent about one-third of all unauthorized families and five out of six unauthorized families with children. Finally, 725,000 families, or 11% of all unauthorized families, had only unauthorized children. (See Figure 7.)
