Instruction Manual Part 3a Classification and Coding Instructions for Live Birth Records The purpose of this manual is to document the specifications for coding and key entry of statistical items that will be tabulated from the birth certificate by the National Center for Health Statistics (NCHS). Primarily, these specifications are used by the 54 registration areas of the United States that submit data to NCHS in electronic form through the Vital Statistics Cooperative Program (VSCP). Under the terms of the VSCP contracts with NCHS, the registration area must incorporate NCHS specifications into their own procedures so that the resultant data files meet the needs of both NCHS and the registration area. The manual is in Wordperfect 7 format (161 KB uncompressed and 42 KB bytes compressed, 3amanual.zip) and ASCII (3amanual.txt). In the future, a pdf version may also be provided. Questions and comments regarding the format of these files should be addressed to Donna Hoyert, Room 820, MSB/NCHS, 6525 Belcrest Road, Hyattsville, MD 20782. Questions about the content of the manual should be directed to the Data Acquisition and Evaluation Branch, NCHS, P.O. Box 12214, Research Triangle Park, North Carolina 27709.
