Summary: I promised another post on divorce and I finally have enough data to write about. So here it is. (This just keeps getting more and more interesting.)

I have analyzed census data from 1880, 1890, 1900, 1910, 1920, and 1930. I restricted the analysis to the white, 15 and older population for the states and territories of the lower 48 states.

In 1880 Utah’s female divorce rate was the third highest in the US, only New Mexico and Nevada are higher. From 1880 to about 1910 Utah’s female divorce rate steadily decreases while the rest of the US tends to increase. From 1910 to 1930 Utah’s female divorce rate rapidly increases, following the national trend. The male divorce rate from 1890 to 1930 follows the national trend.

When looking at the difference in percent male and percent female divorce rates we see that in 1880 Utah had the second highest difference in the US, only Nevada is higher. Utah’s over 15 male to female ratio in 1880 was about 1.1 while Nevada’s was almost 2.5. Utah had a population of 143,964 compared to Nevada’s 62,266. From 1890 and 1900 Utah had the highest difference in male and female divorce rates in the United States. By 1910 Utah’s male and female divorce rate difference was the second only to Colorado. By 1920 Utah had the second highest divorce rate difference, only California was higher. By 1930 the difference in Utah’s male-female divorce rate was equal to the US third quartile.

Because the male and female divorce rates for US states and territories are correlated better than 89% two factor plots provide some additional insight. When the female divorce rate is plotted against the male divorce rate Utah stands out from the national trend for 1880, 1890, and 1900. For 1910 and 1920 it stands out a little. By 1930 Utah is well within national trends.

The only explanation I can see for this is polygamy. It appears that polygamy increased Utah’s female divorce rate noticeably above national trends. And this effect lasted for 20 years after the Church of Jesus Christ of Latter-day Saints officially stopped polygamy in 1890, maybe longer.

The value of this goes beyond academic interest. It can also relate to the gay marriage debate currently going on in the US Supreme Court. If the state can ban polyamorous unions then why not same sex marriage. From this data we can see quite objectively that polygamy increases the female divorce rate. I’m not going to get into that debate now but you can hear the supreme court arguments here and here. Continue reading

Divorce in 1890 Utah: Signs of Polygamy

Summary: I said this post would be interesting. And it is. The LDS Church officially abandoned polygamy in 1890 due to intense government pressure. The 1890 Census Report contains detailed information on divorce that I believe captures evidence of polygamy in Utah. My previous post analyzed the marriage data (Marriage in 1890 Utah: Very Normal).

Firstly, when talking about divorce in 1890 we are dealing with a very small percentage of the population. The median divorce rate for the US was 0.23%. And it turns out that the overall divorce rate in 1890 in Utah is ordinary, right at the third quartile for US states and territories. However, when you look at divorce by age and sex it becomes much more interesting. Above age 34 Utah has the highest or second highest female divorce rate in the US–from 45 on up only Nevada is higher. But this is interesting because Nevada’s total population was 45,761 compared to Utah’s 207,905. Nevada’s male to female ratio was 1.76 and Utah’s was 1.13. Nevada was a much more difficult place for a woman to live and you would expect a higher divorce rate. But Utah?

More can be said. The male divorce rate for Utah qualifies as ordinary (falls between the first and third quartiles) for all age categories. But if you look at the difference between male and female divorce rates by age then Utah really stands out. The national trend is, overall, downward with male divorces eventually exceeding female divorces. The Utah trend is starkly upward, increasing in nearly a straight line from age 15 to 64. Overall, the female divorce rate far exceeds the male divorce rate. Not only does the divergence between the Utah male and female divorce rates increase with age, it also diverges from the national trend. Continue reading
