A group living in the United States in 2004 consisted of fifteen households with no elderly members. There were five single individuals living separately from each other (less than 65 years old). Their incomes were $7,000, $7,500, $8,000, $9,000, and $10,000 respectively. There were five married-couple households (under age 65) with incomes of $10,000, $11,000, $12,000, $13,000, and $14,000, respectively. And there were five two parent (under age 65), two-children households with incomes of $10,000, $15,000, $20,000, $25,000, and $30,000, respectively. What percentage of these households were poor? What was the poverty rate among this group? Note: In 2004, for a single person family in which the individual was less than 65 years old, the poverty threshold was $9,827. The poverty threshold for a couple without children (both adults under 65) was $12,649. For a four-person family with two adults (under age 65) and two children, it was $19,157.
