Left: histogram of the Gaia DR2 Bayesian distance estimates from Bailer-Jones et al. (2018) for the sample of 243 291 stars within 100 pc from the Sun. Right: distribution of the first significant digit of the Gaia DR2 Bayesian distance estimates displayed in the left panel, together with the theoretical prediction of a sample of stars with uniform, constant density. The data have vertical error bars to reflect Poisson statistics, but the error bars are much smaller than the symbol sizes.
