DELAYING MARRIAGE

One-third of men and nearly one-quarter of women have never been married when they reach 34, nearly four times the rates in 1970, Census Bureau figures show.

POSSIBLE REASONS

People are focusing on education and careers. The easing of taboos about couples living together before marriage and having children outside marriage may also contribute.

STILL MARRYING

Americans still do marry -- eventually. In 1970, 8 percent of people 65 and older never had married; now it's 4 percent.
