The baby boom generation likes to watch such family-oriented shows as "The Cosby Show" and "Leave It to Beaver," even though less than a fifth of that age group have traditional marriages, a survey of Americans ages 18-44 shows.

The survey, released Tuesday in the current issue of Rolling Stone magazine, found most Americans in that age group either are unmarried or live in non-traditional families with two working parents or single parents.The report was based on personal interviews conducted with 816 adults by Peter D. Hart Research Associates Sept. 11-20. The margin of error was plus or minus 4 percent.

One-third of those polled were single, 16 percent were divorced or widowed with children and 26 percent were in a marriage in which both the wife and husband worked, the magazine said.

Forty-nine percent said the rise in working mothers is a change for the worse, while 37 percent considered it a change for the better, the survey said.

Another 55 percent said having more children in day care is a change for the worse and 67 percent also said a rise in single parenthood marked a negative change.

Asked to list the television shows with values most important for children, the respondents listed "The Cosby Show," "Family Ties," "Father Knows Best," and "Leave It to Beaver," shows with traditional families, the survey said.

More than half the respondents said they would raise their children the same as their parents did, the survey said.

Sixty-five percent said they had engaged in premarital sex and 8 percent voiced regrets, the survey said.

Thirty percent lived with a member of the opposite sex while not married and 2 percent regretted it, the magazine said.
