I'll let the numbers speak for themselves, but this study shows some interesting stuff for singles to know about our changing world:

Over the past half century, family structure changed dramatically and the number of unmarried Americans increased considerably. During the 1950’s, approximately 80 percent of Americans lived in households headed by married couples; now that number is just less than half. By 2008, more than half will be headed by an unmarried person. As more people remain or become unmarried (e.g., divorce), families are starting to look different. According to a recent study, 24 percent of households in the country are in “traditional” or “nuclear” families (defined as two parents with children) and 16 percent of households are in non-traditional families (defined as a child and a male or female head of household, with no spouse present). In 1950, only 9 percent of children were growing up in one-parent homes, while by 2000 this number had increased to 26 percent.

There are 10 million more unmarried women than unmarried men (56 percent female compared to 44 percent male), primarily because women live longer than men. Twenty-four percent of voting-age Americans are unmarried women, compared to 19 percent who are unmarried men.

For the past half century, unmarried women have been growing steadily as a share of the population. In 1965, only 15 percent of all Americans were unmarried women, compared to 24 percent now. Nearly half (46 percent) of all women are unmarried.

The moral of the story? If you're single, no matter what age or sex, you're not alone.
