Celebrate Your Ten Year Anniversary

The Census Bureau has some statistics on how long marriages last, but what I actually wanted was the conditional probability based on how long you've been married, to see if it went up or down as the marriage went on. I imported the data into R and transformed it, and the graph below shows the conditional probability of staying married for another 5 years, given how long you have been married alredy (I believe I used the data for women).

As you can see, 10 years is when you've passed the trough and the prospects are looking better again.
