Estimates of average varit slaughter weights (kg) plotted against district-level summer population densities (km−2). Filled circles are estimates from the years used by Ims and Kosmo (2001, slaughter data from autumns of 1998–2000), and open circles are for the subsequent years up to 2019 and 1997/1998. The line gives the best fit linear regression line with log(density) fitted as a predictor variable (estimated regression coefficients: intercept = 32.41, SE = 0.47, ln(density) slope = − 3.71, SE = 0.24)
