To determine which of the given reasons does not cause a variance in divorce rates among segments of the population in the United States, we need to examine each option.

1. Age of first marriage: Research has shown that the age at which individuals get married can influence divorce rates. Generally, studies suggest that marrying at a younger age carries a higher risk of divorce. Therefore, age of first marriage can be a factor contributing to variance in divorce rates among different segments of the population.

2. Education: Education level has been found to have an impact on divorce rates. In general, individuals with higher educational attainment tend to have lower divorce rates. On the other hand, lower educational levels have been associated with higher divorce rates. Hence, education is a factor contributing to variance in divorce rates among different segments of the population.

3. Race and ethnicity: Divorce rates do differ across various racial and ethnic groups in the United States. For example, some studies have shown that certain racial and ethnic minorities may have higher divorce rates compared to others. Consequently, race and ethnicity are factors contributing to variance in divorce rates among different segments of the population.

4. Social class: Social class, often measured by income, occupation, and education, has demonstrated associations with divorce rates. Studies have revealed that individuals from lower socioeconomic backgrounds often experience higher divorce rates compared to those from higher socioeconomic backgrounds. Therefore, social class is a factor that contributes to variance in divorce rates among different segments of the population.

After considering each option, it can be concluded that all of the given reasons cause a variance in divorce rates among segments of the population in the United States. Therefore, the correct answer is "None" or "All" of the above options.
