title: [Effect of solar and geomagnetic activity on population dynamics among residents of Russia].
abstract: Basing on the annual data of mortality and birth-rate in Russia in 1867-1897 an attempt to evaluate the role of solar (sunspot number W) and geomagnetic activity (Kp-index) in the population was made. It was shown that mortality is affected by the solar activity and by the absolute value of geomagnetic activity deviation from the mean level: Mi = 3.29 + 0.0044Wi + 1 + 0.030 delta Kp,i (r = 0.78). For the birth-rate the following expression was obtained: Bi = 5.00-0.049 delta Kp,i + 1-0.0012Wi + 3; (r = -0.67). The correlation coefficients between the observed variations of the mortality (and birth-rate) and indices Mi and Bi amounts the values 0.78 and -0.67 correspondingly.
