摘要:

Reproduction rates calculated from specific fertility rates controlled for parity and age, but not fully controlled for nuptiality may be more sensitive to fluctuations in marriage rates than the conventional reproduction rates. Consideration of this factor is necessary before drawing conclusions concerning changes in fertility.

摘要:

This note provides additional information concerning the plan for eliminating the need for callbacks described in the March, 1949 issue of the Journal. Attention is called to the difference in the effects of clustering in using the “nights-at-home” plan or callbacks, and an error in the calculation of the sampling error of the former is corrected.
