The Gender Inequality Index (GII) A. comprises the same measures as the HDI but applies only to women. B. compares indicators for females with those for males within a country. C. assesses the development level of women in a country against the global average for women. D. integrates economic and political indicators of empowerment. E. is not an applicable development indicator for the United States.

B. The Gender Inequality Index (GII) compares indicators for females with those for males within a country. It is a composite measure reflecting inequality in achievements between women and men in three dimensions: reproductive health, empowerment, and the labor market.

Extra: The GII is part of the Human Development Reports published by the United Nations Development Programme (UNDP). Unlike the Human Development Index (HDI), which measures overall development based on health, education, and income, the GII focuses specifically on gender disparities. The three dimensions of the GII can be further explained as follows:

1. Reproductive Health: Measured by maternal mortality ratio and adolescent birth rates. A higher maternal mortality ratio or a higher number of births per 1,000 women ages 15-19 typically indicates greater inequality and less reproductive health services for women.

2. Empowerment: Assessed by the proportion of parliamentary seats occupied by females, and the proportion of adult females and males aged 25 years and older with at least some secondary education. These indicators reflect women's political power and access to education in comparison to men.

3. Labor Market: Analyzed through the labor force participation rate for women and men aged 15 and older. This demonstrates the inequality in employment opportunities between genders.

The GII shows that countries with higher scores (closer to 1) have greater disparities between males and females, while countries with scores closer to 0 have less inequality. It's important to note that the GII does apply to all countries for which data is available, including the United States; however, the relevance and level of gender inequality observed might vary significantly between countries depending on cultural, economic, and political factors.
