This study examines statistics for alcohol consumption and violent crime in Sweden during historic periods when alcohol consumption underwent rapid change. In the first period examined, alcohol rationing was practiced during World War I due to a general food shortage. Alcohol consumption decreased by two-thirds, and the assault rate decreased simultaneously, although the general crime rate increased two to three times. In the second period studied, alcohol was rationed again in Sweden between 1919 and 1955. When the system was abolished in 1955, alcohol consumption increased about 25 percent in 2 years. The assault rate also increased, but by only 8 percent. In 1958 higher taxation pressed alcohol consumption back to the 1954 level. The assault rate, however, did not decrease. In the third period examined, a strike at the State Monopoly for alcohol products resulted in a cut off of liquor to liquor stores and restaurants for about 3 months, and liquor became more and more difficult to obtain. A slight reduction in the more aggravated forms of assault appeared. In three other periods analyzed, strong positive correlation was found between alcohol consumption and violence rates in the four Scandinavian countries; the larger the increase in per capita consumption of alcohol, the stronger the increase in violence rates. The study argues that alcohol consumption is one important factor among many that cause violent crimes. Four references and seven figures are provided.
