Violent crimes by the degree of public danger and the severity of the caused damage far exceed other criminal manifestations. Rapers disseminate the stereotype of aggressively-violent behaviour in the domestic and leisure microenvironment. These criminal offences are mostly condemned from the point of view of the general human morality. The aim of the present article is to examine the impact of socio-economic development level of a country on the level of violent crimes which are committed in that country. Successful prevention of a violent crime, which infringes on such important values as a human’s life and health, demands scrutinizing of its causes. Any crime, the violent one in particular, is not as a rule the result of one cause but is a combination of external and internal factors. The qualitative analysis conducted within the research has proved the conclusion that there is a definite connection between the socioeconomic development level of a country and the trend of the proportion of particular crime types that dominate in it. In less developed countries the proportion of violent crimes is much higher than in the developed ones, where thefts and other crimes against property prevail.
