Numerical calculations based on the collisional-radiative model is made for rate equations of optically thin hydrogen plasma to give the collisional-radiative and population coefficients. Results are tabulated for the range of plasma parameters of Te from 1000 to 256,000 K and ne from 10^6 to 10^20 per cubic cm. Behavior of all the coefficients is analyzed as a function of electron density and as a result the asymptotic expressions of the coefficients at low and high electron-density limits as well as the approximate expressions of the critical electron densities for these asymptotic behaviors are obtained in terms of the rate coefficients for atomic transitions. Effects of trapping of resonance radiation on the coefficients are discussed.
