Natality Detail File, 2001 [United States] (ICPSR 4708)

Principal Investigator(s):


This collection provides information on live births in the United States during calendar year 2001. The natality data in these files are a component of the vital statistics collection effort maintained by the federal government. Part 1 contains data on births occurring within the United States to United States residents and nonresidents, while Part 2 contains data on births occurring in the United States territories of Puerto Rico, the Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands. Geographic variables describing residence for births include the state, county, city, county and city population size, metropolitan statistical area (MSA), primary metropolitan statistical area (PMSA), consolidated metropolitan statistical area (CMSA), New England County metropolitan area (NECMA), and metropolitan/nonmetropolitan county. Other variables include place of delivery, person in attendance, live-birth order, and medical and health data such as the number of prenatal visits, tobacco and alcohol use during pregnancy, method of delivery, medical risk factors, and infant health characteristics. Birth and fertility rates and other statistics related to this study can be found in the National Vital Statistics Report in the codebook documentation. Demographic variables include the child's sex, birthweight, and date of birth, the mother and father's age, race, and ethnicity, as well as the mother's place of birth, marital status, education level, and nation of origin.

Data Collection Notes:

(1) This collection has not been processed by ICPSR staff. ICPSR is distributing the data and documentation for this collection in essentially the same form in which they were received. When appropriate, documentation has been converted to Portable Document Format (PDF), data files have been converted to non-platform-specific formats, and variables have been recoded to ensure respondents' anonymity. (2) Per agreement with NCHS, ICPSR is distributing the data files and text of the technical documentation for this collection as prepared by NCHS. (3) The codebook is provided by the principal investigator as a Portable Document Format (PDF) file. (4) The geographic code structure, as well as populations and population-based rates listed in the codebook documentation, were based on the results of the 1990 Census of Population. As a result, rates were generally larger than would be the case if 2000-based estimates had been used. The magnitude of the overestimate varies by population group. A report containing revised rates based on the 2000 Census can be found via the National Center for Health Statistics National Vital Statistics Natality Web site.


Sample:   One-hundred percent of birth certificates in calendar year 2001.
