Today there are many different kinds of families around the globe. Some people live in traditional families--that is to say, a stay-at-home mother, a working father, and their own biological children. Others live in two-paycheck families--that is, both parents work outside the home. There are many single-parent families; in other words, only a mother or a father lives with the children. Still others have adoptive or foster families (i.e., adults take care of children not biologically theirs) or blended families--in other words, divorced or widowed men and women marry again and live with the children from their previous, or earlier, marriages.Some kids have stepparents-that is,some youngsters under the age of 18 have to take care of kids-either their own or their younger siblings.In different countries around the world, There are also same-sex partnerships--with or without children, childless marriages, unmarried live-in relationships, and so on.
