Oh, I get what you're trying to highlight. I just disagree. I think you missed the point of her article.

If the societal stereotype is that all single mothers are irresponsible youth who got knocked up out of wedlock then going unmarried women are automatically included. Her article was merely pointing out that the majority of single moms got there via divorce, making the stereotype an inaccurate reflection of reality. That doesn't erase or eliminate women who became single mothers through another avenue, such as widowhood, adoption, surrogacy, foster parenting, artificial insemination without a husband, the Heart (rock group) method, or young, unwed, and sexually active.

By the way, I absolutely do NOT fit into the majority. I was not married when I had a planned pregnancy. I did not have a long term partner either. So, I did not become a single mother due to divorce. I became a single mother because I was ready to have a child and I wanted one. I realized I wasn't one to catch myself a husband just to get what I want and if I did I'd end up divorced and on my own anyway. So instead I prepared for having a child and I had one. It's as simple as that.
