WASHINGTON (AP) — Singles, take note: With marriages at an all-time low, states in the South and West rank among the highest for couples hearing wedding bells. But many of these states also have higher rates of divorce.The first-of-its-kind analysis by the Census Bureau, released Thursday, also finds people are waiting longer before marrying for the first time. In particular, the percentage of women who wed as teenagers has dropped precipitously since 1970, while many men are postponing marriage past their college-age years.In all, there were 19.1 weddings performed per 1,000 men and 17.6 per 1,000 women across the U.S. in 2009, while divorces became final for 9.2 of every 1,000 men and 9.7 of every 1,000 women.By region, the South and West had the most marriages, with rates of roughly 19 per 1,000.
