Black District residents were the most frequent victims of violent crimes in 1973, but a greater percentage of the smaller white population were victims of the same crimes, according to study by the Law Enforcement Assistance Administration.

The study also found that twice as many men were victims of violent crimes, such as robbery and assault, compared to women and that the rate of victimization was substantially higher for people under 35 years of age.

The victimization rate was highest for young white men under the age of 34, the young white men under the age of 34, the study showed. The rate for white males between the ages of 12 and 15 was five times the rate for black males in the same age group, the study said.

The report on Washington crime victims, released last week, is a detailed supplement to a 1975 LEAA study of crime victims in 13 American cities. The study was based on a survey of 18,353 District residents over 12 years of age that was conducted in early 1974 by the U.S. Census Bureau for the LEAA. The information collected pertained to crimes committed in 1973, including those not reported to the police. Operators of 1.528 businesses were also interviewed for the study.

The study drew no conclusions about the differences in victimization rates for various population groups.

For example, the study found that there were 55 incidents of violent crimes for every 1,000 white men in 1973 compared to 35 usch incidents for every 1,000 black men.

While the victimization rate was thus higher for a white men that year in terms of the city's total population, there were an estimated 5,355 violent crimes involving black men compared to 3,630 involving black men compared to 3,630 involving white men, the study showed. The study said there were an estimated 153,100 black male and 66,700 white male residents at the time.

An estimated 96,800 crimes involving District residents and businesses occurred in 1973, the study said.

There were twice as many personal crimes of theft - like snatched purses and picked pockets - than personal crimes of violence - like robbery and assault, the study found.

According to the study, white homeowners were burglary victims at a significantly higher rate than black homeowners in 1973. There were 88 incidents of burglary for every 1,000 white homeowners compared to 58 for the same number of black homeowners, the study said.

The lowest burglary rate was found for households headed by a person over 65 years of age, the study said.

Most robberies and household crimes occurred during the night, it said. The study also found that offenders used weapons - commonly a gun - in about half the incidents of rape, robbery and assault. Half the victims of violent crimes attempted to defend themselves, either with physical force or weapons other than guns and knives, the study said.

An estimated 25 per cent of all businesses in the city were burglarized during 1973, the study said.

Forty-two per cent of all personal crimes - such as rape, robbery, assault and larceny - were reported to the police, the study said. Victims who did not report crimes primarily felt that nothing could be done about the incident or that the crime was not important enough to report, the survey found.
