<p>Well, it would be where the real fun lies. I imagine that states like Florida have a low divorce rate for the simple reason that they have a very elderly population - very few people divorce in their 60s. If you take out the college students from OOS, Ma has an average age of 46 - pretty old. Again, not many people divorce at age 50.</p>
<p>Hypothetically,</p>
<p>Two states have identically-sized populations of 150 adults each.<br>
-In state 1, 100 people are between 20 and 25. The remaining 50 people are between 30 and 40.<br>
-In state 2, 100 people are between 30 and 40 and the remaining 50 are in the 20-25 age range.<br>
-Everyone gets married.</p>
<p>Hypothetically, again, the divorce rates are as follows:
state 1, 20-25: 50%
state 2, 20-25: 60%</p>
<p>State 1, 30-40: 20%
State 2, 30-40: 25%</p>
<p>So State 1 has lower divorce rates, right? Nope! Let’s do the math.</p>
<p>Let’s calculate divorce rates:
State 1: 100(.5) + 50(.20) = 50 + 10 = 60 divorces per 150 people
State 2: 50(.6) + 100(.25) = 30 + 25 = 55 divorces per 150 people</p>
<p>YET, you have a better chance of staying married in State 1! (See corresponding lower divorce rates for each age bracket.) The discrepancy comes because there are more young, higher-divorce rate people in state 1. If you normalize for number of people in each age range, you see that you would rather be in State 1.</p>
<p>I know that some people are going to yell and scream before thinking about it, but be a statistics weenie before you do so. A slight shift in the population (different ages of people there, different trends) can show you the why of a statistic. </p>
<p>Now, it is entirely possible that the “red” states, while having higher divorce rates and lower ages of first marriage, still have higher divorce rates, even when normalizing for factors that contribute to divorce. Maybe. Maybe not. Maybe, once you go through all the numbers, it’s better to be in a red state than a blue state, regardless of what age you are when you wed.</p>
