The study by Lawrence B. Finer and Mia R. Zolna examines the incidence and disparities of unintended pregnancies in the United States in 2006. The research combines data from various sources, including the National Survey of Family Growth (NSFG), abortion patient surveys, birth records, and population data. Key findings include: - Nearly half (49%) of pregnancies were unintended in 2006, slightly higher than in 2001 (48%). - The unintended pregnancy rate increased to 52 per 1,000 women aged 15-44 in 2006 from 50 in 2001. - Disparities in unintended pregnancy rates persisted, with women aged 18-24, poor women, and cohabiting women having rates two to three times higher than the national average. - The rate of unintended pregnancies ending in abortion decreased from 47% in 2001 to 43% in 2006, while the unintended birth rate increased from 23 to 25 per 1,000 women aged 15-44. - The study concludes that the U.S. has not made progress in reducing unintended pregnancies since 2001, and efforts should focus on increasing access to effective contraceptives, particularly for high-risk groups such as poor and cohabiting women.The study by Lawrence B.
