Data Challenge

We invite GISRUK conference delegates to develop a novel analysis or visualisation of CDRC and associated data in order to investigate the hypothesis set out in the Economist article “The immigration paradox Explaining the Brexit vote” (Jul 14th 2016) that argues that the rate of change in number of migrants in an area rather than the total headcount influenced the Brexit vote.

We welcome analysis based on parts or all of the CDRC data listed below as well as analysis that links this with other CDRC data and other data holdings.

Issues that might be addressed include but are by no means limited to:

  • Whether Local Authority district is the most appropriate scale at which to ground analysis
  • Whether country of birth or ethnicity as defined by CDRC is the best predictor of voting behaviour
  • Whether the country of birth of recent immigrants plays any role in shaping voting intentions
  • Whether enfranchised members of recently arrived ethnic minority groups are themselves likely to vote for Brexit
  • Whether established party political affiliations affect the share of the Brexit vote
  • Whether voting behaviour varies according to other local, Regional or national circumstances.
