Quite lucky for this year's cohort that they are part of a demographic drop:
The number of births in England and Wales fell in 2013 by the largest annual amount in nearly 40 years, official figures show.
The Office for National Statistics said live births decreased from 729,674 to 698,512 in 2013, down 4.3% which is the biggest fall since 1975.
Interesting that despite the 4% demographic fall, the article you linked still had only a 1% overall increase in children getting their 1st choice school.
And predictably, in areas with more kids at private schools:
The number of successful first-choice applications fell from 77.8 per cent to 65.6 per cent in the City of London, from 72.3 per cent to 66.7 per cent in Kensington and Chelsea, and from 71.2 per cent to 66.9 per cent in Westminster.
It also became harder to secure a first-choice school place in boroughs such as Camden, Barnet, Sutton, Bromley and Croydon.
Despite the 4% fall in demographics in the current Y6 cohort. Hmm.
As you say, it will be very interesting to see what happens for 6th form offers.
You said that grammar offers were out. Do you know whether the stats are out for percentage offered and pass rate? I think that will be telling too.
