Births
Summary: Number of births, birth and parent characteristics
Database Detail
| Name | Births |
| Summary | Number of births, birth and parent characteristics |
| Additional Background | This database report counts of live births occurring within the United States by state, county, child's gender and weight, mother's race, mother's age, mother's education, gestation period, and prenatal care. Births to nonresidents of the United States are excluded from all tabulations by place of residence. Data are derived from birth certificates. Counties with fewer than 100,000 persons are combined together under the label "Unidentified Counties." For confidentiality reasons, totals of 1-5 in counties are suppressed. Data are not available for all counties.
Birth rates and fertility rates are not available from 1995-2002. Birth rates and fertility rates by race and ethnicity are not available from 2020-2021. We expect the NCHS to update these over the next year, and we will publish them when available.
Changes in demographic category classifications in 2010 make some birth and fertility rates comparisions inconsistent with earlier years. Users should exercise caution when comparing time series data across races and/or ethnicities because of this change.
Note that some states, including California, ceased reporting the mother's age and marital status, e.g., Mothers 25-29, Unmarried, Mothers 25-29, Married, etc. in 2017. Instead, while states still report the mother's age, they report marital status as unknown or not available.
See additional documentation from the CDC for changes in some variables over time.

Set APA as default format
APA
Format or style, from the American Psychological Association, is commonly used for footnotes in behavioral and social science publications. APA citation is an author-year-system. It is one of the most common styles used and taught at colleges and high schools. See here for more details, including APA formatting for bibliographies.Chicago
Format or style (also known as Turabian), created by the University of Chicago, is commonly used for footnotes in history, business, and fine arts and occasionally in the humanities, sciences, and social sciences. The Chicago style has two systems of citation. The author-date system (most common in social sciences and sciences) cites sources parenthetically in the text. The notes and bibliography system (most common in humanities) cites sources in numbered footnotes or endnotes which correspond to a superscript number in the text. See here for more details, including Chicago formatting for bibliographies.MLA
Modern Language Association (MLA) format or style is most commonly used for footnotes in the language arts, cultural studies, liberal arts, and humanities. MLA uses short parenthetical citations within the text that are linked to an alphabetical list of work cited at the end of the document. MLA commonly cites using this format: author's last name, first name, title, publication, edition or chapter, and year. See here for more details, including MLA formatting for bibliographies.AMA
American Medical Association (AMA) format or style is most commonly used for footnotes in medicine, biomedical research, nursing, dentistry, and other life sciences. AMA uses numerical superscript for citing sources in-text and refers to a list at the end of the work. These references appear in sequential order of when the sources were cited, instead of alphabetical order. See here for more details, including AMA formatting for bibliographies.Derived From: National Center for Health Statistics (NCHS) at the Centers for Disease Control and Prevention (CDC)
