Correlation between the usual residential population density difference and the peak incidence difference, computed between 2016 and 2021 at the SA2 resolution for the three considered variants: ancestral (blue), Delta (green), and Omicron (red). Data points corresponding to each SA2 area are derived as the averages over 100 runs. Dashed lines represent linear fit for each of the profiles. Total number of overlapping SA2 areas between 2016 and 2021 census years: 2,147. Pearson correlation coefficients: \(r_{ancestral} = 0.4150\), \(r_{Delta} = 0.3426\), \(r_{Omicron} = 0.4509\). These are lower correlation coefficients than the ones obtained for the population size difference, as reported in main manuscript, Fig. 6
