Which of the following statements about poverty rates is not true? a. Black and Hispanic people are more than twice as likely to live in poverty as White people. b. Children are more likely than average to live in poverty. c. Families headed by a single mother are about five times as likely to live in poverty as a family headed by a married couple. d. Older adults are more likely than average to live in poverty.

**Step 1. Evaluate Statement (a):** It is well documented that in the United States, Black and Hispanic individuals have poverty rates that are more than twice that of White individuals. This statement aligns with available data. **Step 2. Evaluate Statement (b):** Children have a higher likelihood of experiencing poverty compared to the overall average. This is due to factors such as family income levels and economic inequality. Thus, this statement is also consistent with known trends. **Step 3. Evaluate Statement (c):** Families headed by a single mother are significantly more likely to live in poverty than those headed by a married couple, with estimates suggesting about a fivefold increase in risk. Hence, this statement is accurate. **Step 4. Evaluate Statement (d):** Statistics indicate that older adults, in many cases, have lower poverty rates relative to children or single-mother households. Therefore, the claim that "older adults are more likely than average to live in poverty" does not align with typical data. **Conclusion:** The statement that is not true is: \( \textbf{d. Older adults are more likely than average to live in poverty.} \)
