Girls lead boys in academic achievement globally

Posted: 26 Jan 2015 09:50 AM PST

Considerable attention has been paid to how boys' educational achievements in science and math compare to girls' accomplishments in those areas, often leading to the assumption that boys outperform girls in these areas. Now, using international data, researchers have determined that girls outperform boys in educational achievement in 70 percent of the countries they studied -- regardless of the level of gender, political, economic or social equality.

Got bees? Got vitamin A? Got malaria? Loss of pollinators increases risk of malnutrition, disease
