The United States has over 1,314,000 child care teachers and of those approximately 4.4% are men (U.S. Bureau of Labor Statistics). This trend has remained the same for  many years. It's similar with other occupations that have women working as the majority (e.g. nursing, dental hygienists).

In the United States there has been a long history of men teaching children. There have been several time periods or waves of trying to recruit more men teach. Historically, it's been the younger the children the fewer the men. One of the pioneers for men in early education was David Giveans in the early 1970s who helped to establish the Men's Caucus with affiliation with the National Association for the Education of Young children www.naeyc.org. David created the first publication dealing with this topic called Nurturing News.

You'll find regional groups all over the United States for example in New England, California and in some major cities: Chicago, Minneapolis, Atlanta.
