The U.S. Census Bureau published a recent report on remarriage.  Here are a couple of graphs that illustrate some of the findings. In the graph below you can see which states have a higher than average remarriage rate ( Purple)  and which states have a lower rate (Green).  Interesting to speculate as to why the Midwest  and Northeast has a lower rate.  May be due to age of the population.  Note that about 25% of all adults (older than 15) are remarried.
