Briefly

By
  • Andrew Chen’s twitter reactions  to a workshop at VUW on regulating facial recognition technologies
  • Interactive exploration of fairness in predictive sentencing algorithms (the same issue as my ‘Kinds of fairness worth working for‘)
  • Beautiful new atlas of the land and people of Aotearoa, “We Are Here“, by Chris McDowall and Tim Denee. Also, their code and data source repository
  • Visualisations of various cities by the street name suffix, eg, Street vs Road vs Avenue
  • From Stuff: ‘Statistics New Zealand challenges Colliers analysis on housing demand’.   There has been a tendency to treat the 2013 2018 Census data as uniformly bad, and it would be good if people were a bit more discriminating — some of the data are of very high quality, and some are of very low quality.  You might, for example, read our report

    “some of the data are of very high quality, and some are of very low quality.”
    However the Report linked doesnt indicate any data is ‘ very low qualitity’. All except 2 categories are said to be high or very high. Only 2 are said to be moderate quality and none are low or very low quality.
    Of course the ratings are ‘qualified’ , that is cherry picked.
    eg
    “Stats NZ rate the quality of Age as very high quality. The panel endorse this assessment at the national and regional council levels of geography. The panel has not seen analyses below regional council level.” oh dear.

    Considering that the report says “For many New Zealanders (an estimated 12.4% of the population), the 2018 Census field
    operation obtained no individual data at all. ” Which is One in Eight persons.
