The passage around this formula

…population totals or the actual SharedResponsesSurvey.csv microdata, and no value of ρR,Y\rho_{R,Y} for any real country is claimed here. What can be computed honestly, using only the paper’s own reported extremes for n — 101 respondents at the low end, 448,125 at the high end [ 1 ] — is how small ρR,Y\rho_{R,Y} would need to be, at illustrative (not dataset-matched) population scales, to produce a cross-country divergence of δ\delta = 0.1 , a magnitude in the range visible between clusters in the paper’s own Fig. 3b…
