The US rate of divorces per married couple: 1.94 % in 2008. This means one out of every 52 couples divorced that year. The lowest was North Dakota with 1.43%. The highest was DC at 3.45% (although it has recently had the LOWEST raw per capita divorce rate.) Most states, though, generally seem at first glance to be higher on this scale if they have higher raw per capita divorce rates, and vice versa. The US per capita rate, in contrast, was 0.72% of the population divorcing every year, or 0.36 divorces for every 100 people. (It's now down to 0.68%, or 0.34 divorces, etc.)
US ratio of marriages celebrated to divorce granted: 1.83 in 2008. This number ranged from 3.1 in North Dakota to 1.3 in Delaware.
Kelly M. Roberts writes: The Healthy Marriage research collection: Trends, Attitudes and Social Implications is now up. Dan Hubler and I put a great deal of time into that project; much thanks go to coordinator Courtney Harrison, and reviewers Bill Coffin and Theo Ooms. Great reasource - quick access to many of the seminal articles building the foundation for healthy marriage.
The Barna Group, which has done major, highly respected studies in the past on the demographics of marriage, divorce and religion, released a major new survey March 31, based on interviews conducted in 2007.
Some of its findings:
25% of Americans over 18 have been divorced. One-third of Americans who have ever married have divorced at least once. (Note: that's not the same as one-third of all marriages.)
The highest-divorce groups (per marriage):
downscale adults (39%) [i.e. income <$20,000, no college] Baby Boomers
(38%) members of non-Christian faiths (38%)
social and political
liberals (37%) African-Americans (36%),
The least-divorced groups (per marriage):
Asians (20%) upscale
adults (22%) [i.e. income >$75,000, college grads] evangelicals (26%), Catholics (28%), self-described
social and political conservatives (28%)
Groups with near-average divorce rates (per marriage): Whites 32% Hispanics 31% Moderates 33% born-agains 33% [apparently very distinct from evangelicals although there's considerable overlap. Barna specializes in polling distinctions of religious identity.] atheisits and agnostics 30% [rate may be distorted by their lower marriage rate, which is 65% -- average is 78% and evangelicals are 84%]
