Although disputed by scholars past and present (Polit & Falbo, 1987; 1988, Newman, 2011), the popular belief is that only children are self-centered, spoiled, in constant need of the spotlight, and socially inept. Nevertheless, more and more American couples are choosing single-child families. The percentage of women who have one child has more than doubled in the past 20 years up from 10% to 13% (U.S. Bureau of the Census, 2011). In 1970 families averaged 2.5 children compared to today's 1.8 (The National Center for Health Statistics, 2011). The Only Child (2011) reported that there are 20 million only child households in the United States alone.
The changes are in part, economically driven: raising one child costs less than raising two or more. But people are also marrying later in life and in so doing, there is less time to have more than one child. Career-oriented women in particular have been having babies later in life. Susan Newman's recent book, The Case for the Only Child: Your Essential Guide (HCI, 2011) addresses many of these issues.
While I do not wish to dispute the research which casts a positive light on only children, I would like to share a few personal quirks which I believe are a result of my being raised an only child. Please keep in mind this isn't meant to be a sweeping generalization of the only child. I'm well aware that not all only children are raised alike. I also realize that some adults who grew up with siblings may have the same quirks. I'm simply sharing 10 personal idiosyncrasies with the hope that some will resonate with you. If you find them somewhat humorous, all the better:
