Final answer:
The statement that older married couples argue more than younger married couples is false. Mature couples often develop better communication skills, and having multiples can lead to more strain than age. The median age for first marriages has risen, suggesting possibly stronger relationships.
Step-by-step explanation:
The statement 'Older married couples argue more than younger married couples do' is false. Studies have suggested that as people get older, they may find their values and life goals change, which could affect marital satisfaction. However, this doesn't necessarily lead to more arguments. Instead, many mature couples have been found to have developed better communication and conflict resolution skills over time. Additionally, factors such as raising children, particularly multiples like twins or triplets, have been suggested to have a more significant impact on marital strain than age alone. The median age of first marriage has increased for both men and women, which indicates that couples are taking more time before committing to marriage, possibly leading to more established relationships that are less susceptible to frequent arguments.
