The answer correctly uses the national estimate of 2% for adopted children, which aligns well with the sample size of 1000, leading to an estimate of 20 adopted children. However, the critique lies in the reliance on national averages without acknowledging that state-specific data may differ due to various factors such as demographics and local adoption policies. Thus, while the answer is reasonably accurate, it lacks specificity regarding California's unique context, which may yield a different adoption percentage than the national average. Providing a caveat about the variability and importance of localized data would enhance the completeness of the response.

The answer is factually accurate and uses a reasonable methodology. The 2% adoption rate is consistent with U.S. Census data and academic research showing approximately 2-2.5% of U.S. children are adopted. The calculation (2% of 1000 = 20) is correct. The answer appropriately acknowledges potential variation in California-specific data while justifying the use of national averages as a proxy. However, the answer could be slightly more complete by noting that: (1) adoption rates can vary by age group, with higher percentages among older children in the sample range, and (2) California's adoption rate may differ from the national average due to its unique demographics and foster care system size. These are minor omissions that don't significantly impact the answer's reliability.
