Abstract Consideration of the orbits of meteorites indicates that their inclinations to the ecliptic are small and may be neglected in many statistical treatments. With this assumption the variation in the rates of meteorite falls per unit area on the surface of the earth is derived for meteorite velocities of 15, 20 and 25 km/sec as a function of both ecliptic and geographic latitude. At low meteorite velocities the variation is small but for meteorites with average or above average velocity the rate of impact in polar regions decreases to 50 or 60% of the equatorial values.
