Oh FGS this is getting even more ridiculous. I thought the whole point of the census is for accurate data collection for planning resources and for studying population trends.
The Office for National Statistics, which runs the census, said it would be “continuing to ask the binary choice male/female sex question. This approach is unchanged since 1801.” Its guidance says the answer you give can be different from that on your birth certificate.
Of course the male female sex question is binary. Sex IS binary.
But what about people who feel themselves to be non binary? Will there be an 'other' option for them? If not, why not? And if there is, what use will the data be if EVERYONE declares they are 'other'?
I despair.
