The correct answer to this open question is the following.
Although there are no options attached or specific context, we can comment on the following.
Migration patterns impact women differently because depending on their own circumstances and the country in which they live, women are exposed to many different things that affect them and their children.
For instance, in many Central American countries such as El Salvador, Nicaragua, and Honduras, men leave their homes to immigrate to the United States. Meanwhile, women stay at home with their children, living the exact same problems: poverty, hunger, disease, and lack of opportunities. So if the husband can cross the US-México border and get a decent job in the United States, that is a matter of luck and the pass of time. During that process, women have to feed and protect their children under the worst of circumstances. And that is a major issue for women.
What governments can do to protect women from the negative effects of migration is to establish a series of programs and legislation that protect women while their husbands are away trying to get a fortune in the United States, for instance. This means that the government should invest to spend some money on social programs to guarantee basic living standards for mothers and children. For example, the opportunity to access health systems and public education to their children.
