What is the reported annual trend in birth rates for the 15-17 age group in 2011?

The reported annual trend in birth rates for the 15-17 age group in 2011 indicates a decline, which aligns with the correct answer. A decrease by 10% reflects a broader trend observed in that period where teenage birth rates were experiencing a significant downward shift. This decline can be attributed to various factors, including improved access to contraception, increased education on sexual health, and shifting societal attitudes towards teenage pregnancy.

The context of this reduction is important, as it demonstrates public health successes in interventions aimed at decreasing unintended pregnancies among adolescents. This trend is significant in discussions surrounding perinatal mental health as well, as lower rates of teenage pregnancy can lead to better mental health outcomes for both young mothers and their children. The other choices reflect either increases in birth rates or more moderate decreases that do not align with the data from that year.
