The annual per capita divorce rate for the 12 months ending in September, 2007 -- the latest figures currently available -- show an annual rate of 0.36 divorces (i.e., 0.72 people getting divorced) for every 100 people in the population. For the latest figures, check the National Vital Statistics Reports at http://www.cdc.gov/nchs/products/pubs/pubd/nvsr/nvsr.htm.
An earlier month's report had showed a rate of 0.34% for the 12 months ending in June 2007, but the rate is now 0.36%, the same as the 2006 rate.
Official state-level divorce rates still are available only through 2004.
