L.N.E. signifies a low number event. When the number of low birth-weight babies in a given county and year is fewer than 5, the data is suppressed to protect the confidentiality of individuals.


Before 2007, the prenatal care question asked for the month of pregnancy in which prenatal care began.

Beginning in 2007, the question now asks for the date of last normal menses and the date of the first prenatal visit.  The month prenatal care began is then calculated from these two variables. 

If the day of the month was unknown, the day of the month was calculated using a program that the National Center for Health Statistics (NCHS) has developed. NCHS has observed a decrease in the percent of mothers receiving care in the first month for all states who have adopted the revised certificate and considers it to be the result of better reporting.
