Do you have a link to the actual CDC report you quote? The numbers just make no sense.

These are the only CDC numbers on divorce i could find
Lets see how to get only 6.6% of marriage survive 10 years.
In the same data it also states the marriage rate is 6.8 per 1000 and divorce rate is 3.4 per 1000.
So it seems 50% marriage will last.
From the pew research site, it states that 40% of marriage is remarriage. So the rate for divorce + remarriage is 6.12 while the marriage rate is 6.8. That means first time marriage that end in failure can go up to 90%.
However it should be less then 90% because we are not accounting for people who married for more then one time get divorce again. If we use the statistic of 40% of divorce are from remarriage and should not be counted again, first time marriage failure maybe as low as 70%.
So it is at minimum 70% and maximum 90%. Given that some people have surviving second marriages, or dies before getting second / third divorce, the numbers move closer to 90%.
For whites, the remarriage rate is 60% so the minimum failure rate rise to 80%. So it is likely 90% of brothers that marry are divorce at least once.
So yeah 90% of first time marriage failure does not seem too exaggerated. And the non white brothers first marriage failure rate does not fall too far behind.
So we know the 50% marriage failure rate is a lie, they just need to hide the remarriage statistic.
