The first bar chart illustrates the number of married and divorced couples in the US from 1970 to 2000, while the second chart shows figures for the marital status of adult citizens in both 1970 and 2000.
From the charts, we can observe a slight falling trend in the number of marriages, and a brief rise followed by a gradual decline for divorces over the 30-year period. It is also clear that married people predominated at the beginning and end of the same period.
In 1970, there were 2.5 million marriages, and this figure remained constant until 1980, before falling gradually to 2 million in 2000. The number of divorces was relatively low in 1970 at 1 million. This figure saw a noticeable increase in 1980 to slightly more than half the number of marriages, before it declined along with marriages to remain at 50% thereof in 2000.
Between 1970 and 2000, the proportion of the population who were married had dropped by 10% from 70%. The percentage who were widowed witnessed a much slighter reduction from 8% to 6%. In contrast, those who had never married or were divorced had risen from 15% to 20% and from 2% to 9% of the population respectively.
