Final answer:
The United States has the highest teen birth rates among the countries listed, influenced by its economic development level and societal factors. European countries like the Netherlands have lower rates due to different approaches to sex education and liberal attitudes toward sex.
Step-by-step explanation:
Among the countries listed, the United States has historically had the highest rates of teen births. The teen birth rates in highly developed countries like Austria, Canada, and Germany are generally lower than those in the United States. Factors that influence these rates include societal attitudes toward sex, levels of sexual education, accessibility to contraception, and overall fertility patterns in the country. It is commonly known that certain European countries like the Netherlands have very low teen birth rates, due to comprehensive sex education and liberal attitudes towards sex. In contrast, countries with higher fertility rates and intermediate levels of economic development, such as the United States, tend to have higher rates of teen births.
