This article discusses one of the most important geophysical factors, which produces an impact on the demographic processes and reflects the nature of variability in the anomalous gravity field intensity in space. The article characterises the horizontal gravity gradients, which vary from 0,2 to 2,5 mGal/km. At the end, the article gives an ecodemographic evaluation of the territory of Latvia by the gradience of the anomalous gravitational field.
