Disavantage for babies born end of the academic year

A recent newspaper article I found on the disadvantage of having you babies in the summer in the UK.
The article concludes that babies born towards the end of the academic year have a slightly lesser chance of going onto higher education and going to top Oxbridge university

In the case of the Hong Kong international school system, this would be babies born at the end of the year.

Any comments ?
