00:00research from Northwestern University published in the American Economic Review suggests a
00:09significant link between a child's birth weight and their academic performance throughout primary
00:14and secondary education this implies that a longer gestation period maximizing time in
00:20the mother's womb may be beneficial for a child's future academic success the study involved an
00:27extensive analysis of data from over 1.3 million children and nearly 15,000 pairs of twins tracking
00:34their development from birth through high school for example children born weighing three kilograms
00:40typically scored in the 46th percentile for reading and math in primary school in contrast those born
00:47at 4.5 kilograms averaged the 57th percentile in the same subjects crucially these findings were
00:55consistent even among twins the twin with the higher birth weight generally achieved better
01:00academic results this correlation held true regardless of other influential factors such as
01:06school quality race socioeconomic status maternal education or family environment David Figlio a
01:15co-author of the study clarified that a child born healthy does not necessarily have a completely formed
01:21brain however he also offered a reassuring note stating that birth weight does not seal a child's destiny
01:28indicating that while it is a factor it is not the sole determinant of a child's future
