Stats SA has published Census 2022 data broken down to police precincts, which has allowed me to produce some more detailed maps than previously. New blog post with images: adrian.frith.dev/census-2022-...
Census 2022 maps based on police district data
In August of this year Stats SA released
data from Census 2022 at the level of police districts (precincts). With 1,167

I couldn't resist the opportunity to use this meme image to announce that yes, I'm officially on the spectrum. Level 1 autism - what would previously have been called Asperger's Syndrome.

Moment of interest as I learned that Zohran Mamdani, promising candidate for Mayor of New York, attended the same primary school as me for a couple of years. Immediately followed by moment of horror as I realised that he was several grades below me. 😱 I should not be that old!

SA's Electoral Reform Panel is starting its public consultations this month, so it seems a good time to recall that we already did this once with the Electoral Task Team in 2003.

It appears that Stats SA will only be releasing data at ward level, and not small area level. This is ... not good.

Some preliminary mapping now that Census 2022 data has started trickling out.
I don't know what's happening in Richtersveld where population supposedly doubled in 10 years. (6.8% per year = double in 10.5 years.) Maybe a data validity issue because of Census undercount.

For those who might be wondering: Stats SA is releasing the Census national results on Tuesday, but that's only the high-level figures. I will only be able to update dotmap.adrianfrith.com and census2011.adrianfrith.com when the detailed data comes out in a later phase.
