Single parent
In the United States, 83% of single parents are mothers. Among this percentage of single mothers: 45% of single mothers are currently divorced or separated, 1.7% are widowed, 34% of single mothers never have been married. Although decades ago, having a child outside of marriage and/or being a single mother was not prominent. Census information from 1960 tells us that in that year, only nine percent of children lived in single parent families. Today four out of every ten children are born to an unwed mother.
Montessori in the United States
In the 1960s, a growing homeschool movement arose in the United States, due to parental concern about the quality and nature of the government system of free public schools. By 2003, the number of homeschooling children in the United States rose to over 1 million, an increase of some 29% from 1999. In this growing context, parents have been seeking to use the Montessori Method as well. For example, Elizabeth Hainstock, a homeschooling mother in the United States, used the Montessori method with her own children in the 1960s, and wrote about her experiences and knowledge on the subject in several books to guide other parents interested in using the Montessori method at home. No reliable figure exists of the number of homeschoolers using materials or methods borrowed from Montessori.
