If you educate a man you simply educate an individual, but if you educate a woman you educate a family

Girls have the right same right to education as boys. Educated girls can make informed choices - and from a far better range of options. Educating girls saves lives and builds stronger families, communities and economies.

An educated female population increases a country's productivity and fuels economic growth. Some countries lose more than $1 billion a year by failing to educate girls to the same level as boys.

Often, girls are marginalised and are out of school simply because they are girls and it is not the cultural norm. Their chances of getting a quality education are even smaller if they come from a poor family, live in a rural area or have a disability.

There has been improvement in gender equality in education. Between 2000 and 2015, the number of girls for every 100 boys in primary education rose from 92 to 97 and from 91 to 97 in secondary education.

The number of countries that achieved gender parity in both primary and secondary education from 2000 to 2015 increased from 36 to 62. But the overall improvement does not tell the full story. Some parts of the world, including sub-Saharan Africa and South and West Asia, are not making as much progress.
