The term 'birth rate' specifically refers to the number of live births in a given year for every 1,000 people in the total population. This measurement provides a standardized way to compare the fertility levels of different populations, regardless of their overall size. By using a per 1,000 population basis, it allows sociologists and demographers to analyze trends over time and across various regions more effectively.

In contrast with the other options, measuring births specifically among women or looking at total births over a decade does not provide a complete picture relative to population size. Also, the percentage of women who give birth would not convey the same statistical insight as the birth rate does, as this would exclude many demographic factors, such as age distribution and population growth. Therefore, the correct choice reflects the broader context in which birth rates are useful for understanding societal trends.
