PIP: The National Survey of Family Growth staff contracted with researchers for an improved measurement of unintended pregnancy for Cycle 6 in the year 2001. There is a need for additional data related to unintended pregnancy for individuals practicing contraception, and for individuals who wanted to be pregnant but are not using any method. Substantive additions for the study include motivation desire to avoid pregnancy, ambivalence, and reasons for unintended pregnancy. Moreover, the introduction at the beginning of the "intendedness" series is to know about the feelings of a woman right before she becomes pregnant. A question is asked on the method or methods used in the month of conception. The impact of the question on the respondents needs to be assessed.
