own children under 5 years old and 5 to 9 years old are the survivors of births in the respective periods from April 1, 1955, to March 31, 1960, and from April 1, 1950, to March 31, 1955. With the aid of various adjustments, described in the forthcoming monograph sponsored by the Community and Family Study Center of the University of Chicago, it is possible to use the data to derive average annual age-specific birth rates, total fertility rates, and other measures such as gross and net reproduction rates, for the birth periods. The adjustments make provision for children not living with their mother and for the effect of mortality on women and children between the time the children were born and the date of the census, and also include interpolation and combination of data. By use of these adjustments it is possible to derive birth rates by social and economic characteristics that are available from decennial censuses but not from birth registration data.
Illustrative materials appear in table B. The census data were not adjusted for any undercount of women and children under 5 because there is evidence that nearly equal proportions of women and children were missed in the 1.960 Census.
4 Data by type of residence in the detail given in table B are not available from birth registration data.

41960 Census of Population, Vol.I, Characteristics of the Population, Part 1, U.S. Summary.
1 Obtained by multiplying published rates (Vital Statistics of the United States, 1964, Volume I, Nativity, tables 1-D and 1-E) by the relative completeness of the count of women by age and color as estimated from the 1960 Census. The published rates allowed for underregistration of births but not for any undercount of women in the bases.
