  1. † The percentage change is from 1981–84 to 1996–99, estimated by fitting a ordinary least squares regression (unweighted) to the SIIs to work out the regression-estimated change in the SII over time, the regression estimated value for 1981–84, and hence the percentage change.
  2. ‡ We conducted ordinary least squares regression of the SII on census year (weighted by the inverse of the variance of the SII), and used the p-value for the census year term as our p-value for trend.
