SCHS: Basic Automated Birth Yearbook (Baby Book)

• A "live birth" is the complete expulsion or extraction from its mother of a product of conception irrespective of the duration of pregnancy, which, after such separation, breathes or shows any other evidence of life, such as beating of the heart, pulsation of the umbilical cord, or any definite movement of voluntary muscles, whether or not the umbilical cord has been cut or the placenta is attached. (Definition adopted by the World Health Organization in 1950.)
• An "unmarried" mother is one who has never been legally married or who has been widowed or legally divorced from her husband for more than 280 days.
• "Birth order" is the sum of all previous deliveries (live births plus other reported terminations, i.e., spontaneous and induced at any time after conception) plus the present live birth.
• "Birth weight" is expressed in grams. A low-weight birth is defined as a live born infant weighing less than 2500 grams (5 pounds, 8 ounces or less) at birth, regardless of the period of gestation. (Birth Weight Index recommended by the expert group on prematurity of the World Health Organization, 1950.)
• "Age of mother" is her reported age in completed years on her last birthday.

Residence Allocation

Births are assigned to the usual residence of the mother, regardless of the place of occurrence.

Note: Counts and percentages in this report are based on live births filed with the local registrar before April and processed in the state office prior to May of the year following the birth. The number filed subsequently is considered negligible for statistical purposes.

Example 1

Table 4: North Carolina Resident Births for 2001 by Education of Mother and Birth Weight in Grams for Minority Women

Tables in this book produced by SAS System programming are of two basic types. Example 1 is the first type. It is a tabulation of the resident births in North Carolina for selected criteria where each birth is counted only once in the table.

• Section one of Example 1 is the title and general description of the tables in a group. In Example 1, we have resident births for the year 2001 with education of mother by birth weight in grams controlling for race.
• Section two of Example 1 is the specific variable that is controlled for the table. In Example 1, the control variable is race equals minority.
• Section three of Example 1 is the table itself. At the top of this section is the name of the row variable and the name of the column variable. In example 1 the row variable is "Education of Mother" and the column variable is "Birth Weight in Grams".
• The body of the table is divided into cells. Across the top are the values of the column variable (birth weight in grams). In Example 1 these values are: < 1500, 1500-2499, >=2500, unknown, and total. Down the left side are the values of the row variable (education of mother). In Example 1 these values are: None or Elem., H.S. 1-3 Years, H.S. 4 Years, Col. 1-3 Years, Col. 4+ Years, not stated and total. Down the right side are the row totals. In Example 1, row one, the total births to minority women with None or Elem. education equals 761. Across the bottom are the column totals. In Example 1, column one, the number of births to minority women where the birth weight is under 1,500 grams equals 1,079. The remaining cells each contain the frequency (i.e., the number of births for the specified education and birth weight). To determine the percentage, divide the frequency by either the column total or the row total.

Example 2

Table 22: North Carolina Resident Births for 2001 by Conditions of Newborn and Birth Weight in Grams for Minority Women

Tables in this book produced by SAS System programming are of two basic types. Example 2 is the second type. It is a tabulation of the resident births in North Carolina for selected criteria where one birth may be counted more than once in the table.

• Section one of Example 2 is the title and general description of the tables in a group. In Example 2, we have resident births for the year 2001 with conditions of the newborn by birth weight in grams controlling for race.
• Section two of Example 2 (the line just above the body of the table) is the specific variable that is controlled for in the table. In Example 2, the control variable is minority women.
• Section three of Example 2 is the table itself. At the top of this section is the name of the row variable and the name of the column variable. In Example 2 the row variable is "condition of newborn" and the column variable is "birth weight in grams". Down the left side of the table (below row variable name) are the values of the row variable. In Example 2 these values are: none, assisted ventilation, all others, one or more, unknown, and total. Across the top of the table (below column variable name) are the values of the column variable. In Example 2 these values are: <1500 grams, 1500 - 2499, >=2500 plus grams, unknown, and total.
• The body of the table is divided into cells. Each cell is the number of births with a specific condition or conditions and birth weight in grams for minority women. In Example 2 the number of births that had assisted ventilation and weighed less than 1,500 grams was 355. In this example, if a birth had assisted ventilation and another condition of the newborn, then that birth would be counted three times in this table (under "assisted ventilation", "all others", and "one or more"). However, the birth is counted only once in the column total.
