**Question:** The magnitude of completed family size can be obtained from
A. Total fertility rate
B. Total number of children ever born
C. Total number of children ever wanted
D. Total number of children ever conceived
**Correct Answer:** B. Total number of children ever born
**Core Concept:** Completed family size is the total number of children a couple has had, regardless of whether they wanted or intended to have more children in the future. Understanding completed family size is important for evaluating family planning programs, demographic studies, and understanding population dynamics.
**Why the Correct Answer is Right:** The correct answer, "Total number of children ever born" (option B), represents the actual number of children that a couple has had throughout their lifetime. This option directly quantifies the family size, unlike the other options. Options A, C, and D are related to different aspects of family planning and fertility, but they do not accurately represent the completed family size.
**Why Each Wrong Option is Incorrect**:
A. Total fertility rate (TFR) - TFR is the average number of children born per woman during her reproductive years. It represents the potential family size, not the actual completed family size.
C. Total number of children ever wanted (or desired) - This option reflects the couple's intended family size, but does not account for the actual family size achieved. Wanting more children in the future does not define completed family size.
D. Total number of children ever conceived - This option considers the total number of pregnancies a couple has experienced, including those that resulted in miscarriages, stillbirths, and abortions. Completed family size is determined by the actual number of children born, not all pregnancies.
**Clinical Pearl:** Understanding completed family size provides valuable information for assessing a couple's reproductive history and demographic data. It helps in evaluating family planning programs, assessing contraceptive use, and studying population dynamics.
