Gender Parity Index and more

Hi class! This time our data team focuses on Gender Parity Index across countries.
Gender Parity Index (GPI) is a socioeconomic index usually designed to measure the relative access to education of males and females. It is calculated as the quotient of the number of females by the number of males enrolled in a given stage of education. (If the value is less than 1, then it means that the number of males enrolled is greater than that of females enrolled)
Here is the source from UNStats.

And this is my summary!
U.S.A.: 1.37 (in 2013)
China: 1.15 (in 2013)
Peru : 1.09 (in 2010)
Pakistan: 0.98 (in 2013)
Mexico: 0.96 (in 2013)
India: 0.92 (in 2013)
Japan: 0.90 (in 2012)
Viet Nam: 0.90 (in 2013)
Korea: 0.75 (in 2014)
Singapore: – (no data found)
To be honest, I’m very surprised by the fact there is less differences across Asian countries than I thought and there is almost no correlation with gross enrollment ratio that I posted last time (http://edblogs.columbia.edu/inafu6653-001-2017-1/2017/02/08/international-comparison-gross-enrollment-ratio/). Another striking fact is Korea and Japan is lagging behind even within Asian countries.
And rather than just showing this alone, we also wanna share World Economic Forum’s Global Gender Gap Rankings in 2016. This index is composed mainly of four factors (economic participation and opportunity, educational attainment, health and survival, and political empowerment)
U.S.A.: 45th
Singapore: 55th
Viet Nam: 65th
Mexico: 66th
Peru : 80th
India: 87th
China: 99th
Japan: 111th
Korea: 116th
Pakistan: 143rd
