Builders Focus On Non-Nuclear Families
According to the National Association of Home Builders (NAHB), "married couples with children made up 50% of new home buyers in 1985 but only 33% in 2001. Meanwhile, the percentage of single people buying new homes doubled to 14% in 2001 from 7% in 1985, and the percentage of married couples without children remained steady but high at 34% in 2001, compared to 33% in 1985... The market has also grown because developers have realized the financial and consumer power of couples without children, singles and small households."
