Births in the United States, 2016
NCHS Data Brief
|November 21, 2017
Summary
Key 2016 U.S. birth data reveal trends in fertility rates and maternal health indicators like cesarean delivery and preterm births. Analysis compares 2016 rates to 2015 and recent highs or lows.
Area of Science:
- Reproductive Health
- Demographic Statistics
- Maternal and Infant Health
Background:
- Maternal and infant health indicators provide crucial insights into population well-being.
- Tracking demographic trends is essential for public health planning and resource allocation.
Purpose of the Study:
- To present key demographic and maternal-infant health indicators from 2016 final birth data.
- To analyze trends in general fertility rate, age-specific birth rates, cesarean delivery, preterm births, and multiple birth rates.
- To compare 2016 data with 2015 and recent historical high/low rates for context.
Main Methods:
- Utilized final birth data from the United States for the year 2016.
- Calculated general fertility rate (births per 1,000 women aged 15–44).
- Analyzed age-specific birth rates, cesarean delivery rates, preterm birth rates, and triplet/higher-order multiple birth rates by maternal age.
Main Results:
- Presents detailed 2016 data for selected maternal and infant health indicators.
- Compares 2016 indicator rates against 2015 and relevant historical benchmarks.
- Highlights trends across different maternal age groups.
Conclusions:
- The report provides a comprehensive overview of 2016 U.S. birth statistics.
- Identifies significant demographic and health trends impacting maternal and infant outcomes.
- Establishes a baseline for future monitoring and intervention strategies in reproductive health.

Population Growth
28.8K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

Birth Control Methods
6.9K
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Applications of Life Tables
378
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

Nondisjunction
5.2K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Nondisjunction
82.3K
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.

Sexually Transmitted Infections
1.3K
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
