HOW AMERICANS LIVE
New York is America's largest city, however, it may also be the country's loneliest city. People living
alone make up forty-eight percent of all households (家庭) on the island of Manhattan.
"I think it's the best way to live," James Combo, a 35-year-old New York musician said,"If you want to
make a mess, you can make a mess. If you want to paint the walls a certain color, you can do it."
In the USA, there are more single-person households than classic nuclear families----a married couple and
their natural children----according to a latest report. Other cities with high percentages (百分比) of single
households are Washington DC, St. Louis, Denver and San Francisco.
The high number of single households shows today's values. People living alone, especially unmarried
women used to have something to do with sadness. That feeling is no longer true. Self-esteem (自尊) isn't
based on having children and being married any more.
