Abstract: We check if the first significant digit of the dispersion measure of pulsars and Fast Radio Bursts (using the CHIME catalog) is consistent with the Benford distribution. We find a large disagreement with Benford’s law with χ2 close to 80 for 8 degrees of freedom for both these aforementioned datasets. This corresponds to a discrepancy of about 7σ. Therefore, we conclude that the dispersion measures of pulsars and FRBs do not obey Benford’s law.
