Trend in Portugal’s Divorce Rate

Marital History of U.S. Men from 1940-2012


Over time this figure shows the changes in marital history of men in different birth cohorts (a birth cohort is all the men born in a specific time period).  The men born in the years 1940-44 were ages 77-82 when this report was created.  The men born in the years 1975-79 were ages 32-37.  Keep this in mind when looking at these data.  The younger group (1975-79) is still likely to experience more changes in their marital history.

Nevertheless, you can still see some trends.  On average, about 2/3 of men are married at least once and this has remained constant over much of this period except this most recent period (those born 1975-79 who still have a chance of marriage).  A more difficult trend to determine in whether 2nd and 3rd time marriages are declining– the cohorts between 1950-1969 seem to suggest this trend.  The increase in the number of men never getting married is also apparent, but there is also a trend of marrying at older ages so some of the men born between 1970-1979 may still get married.  Marital History of Men By birth cohorts 2008-2012

Remarriage Rates by State – United States 2008-2012


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.

75 Years of Change in American Families– 1910 – 1990


A good description of the changes in American families from 1910- 1990.

For example, see this figure for how fertility has changed over the 20th century.  The number of children per family declines until after WWII, then increases dramatically until it reaches 3.7 children per woman (family) in the late 1950s, (higher than in the 1920s), then declines again in the earlier 1970s to less than 2 children per woman (family).
