As can be seen from the first bar chart, 2.5 million marriages took place in America in 1970 and 1980. This figure then dropped gradually to approximately 2.3 million in 1990 and to 2 million at the end of the 20th century. The number of divorced case in 1970 was only two fifths of that of marriages, with 1 million case. The gap between marriages and divorces was significantly shortened in 1980 when the number of divorce went up to just under 1.5 million, a record high
in the given period. This figure then dropped back to the 1970’s level in 2000.
The never married and divorced group experienced a slight increase of around 8% in the percentage of American adults from 1970 to 2000. In 2000, 20% of American adults were reported to stay single all their life while nearly 10% were reported to be in divorced status. The proportion of the married and widowed, on the other hand, accounted for smaller shares of the number of American adults between 1970 and 2000. The married group witnessed the greatest change with a 10% drop, while the fall in the percentage of widowed group was less significant with just only 2%.
