National Survey of Family Growth

Last updated

The National Survey of Family Growth (NSFG) is a survey conducted by the National Center for Health Statistics division of the Centers for Disease Control and Prevention to understand trends related to fertility, family structure, and demographics in the United States. [1]

History and details

The National Survey of Family Growth is conducted in five-year cycles. In each cycle, surveys are administered via personal interviews with people at homes. The interviewees generally comprise only the civilian, non-institutionalized population. [2]

The cycles so far have been: [3]

While Cycles 1–5 surveyed only women, Cycle 6 and later surveyed both men and women and used households as the unit of analysis. Cycle 6 surveyed 12,571 respondents 15–44 years of age: 7,643 females and 4,928 males. The 2006–2010 NSFG surveyed 22,682 interviews: over 10,000 interviews with men and more than 12,000 interviews with women. [2] In 2006, the NSFG shifted from periodic surveys to continuous interviewing. [11] For Cycle 6 onward, the surveys were conducted in person by female interviewers who are hired and managed by the University of Michigan Institute for Social Research. [2] The survey samples are intended to be nationally representative but not necessarily representative at subnational levels (such as individual states, ethnicities, or religions). [2]

Data

For the survey cycles that have been completed, data is available both in the form of portable document format summaries and as full data files. In addition, program statements are available in SAS, SPSS, and STATA. [4]

Key statistics are also browsable online. [12]

NSFG data is also mirrored on the website of the University of Michigan's Inter-university Consortium for Political and Social Research. [13]

Academic research

The NSFG website claims that the NSFG has been cited in "more than 1,300 journal articles, NHCS reports, and book chapters shown in our bibliography." [2] The research citing the NSFG is concentrated more on topics related to family planning, contraception, abortion, and fertility. [14] [15] [16]

Fertility awareness (FA) refers to a set of practices used to determine the fertile and infertile phases of a woman's menstrual cycle. Fertility awareness methods may be used to avoid pregnancy, to achieve pregnancy, or as a way to monitor gynecological health.

<span class="mw-page-title-main">Combined oral contraceptive pill</span> Birth control method which is taken orally

The combined oral contraceptive pill (COCP), often referred to as the birth control pill or colloquially as "the pill", is a type of birth control that is designed to be taken orally by women. It is the oral form of combined hormonal contraception. The pill contains two important hormones: a progestin and estrogen. When taken correctly, it alters the menstrual cycle to eliminate ovulation and prevent pregnancy.

<span class="mw-page-title-main">Family planning</span> Planning when to have children

Family planning is the consideration of the number of children a person wishes to have, including the choice to have no children, and the age at which they wish to have them. Things that may play a role on family planning decisions include marital situation, career or work considerations, financial situations. If sexually active, family planning may involve the use of contraception and other techniques to control the timing of reproduction.

Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. The fertility rate is the average number of children born during an individual's lifetime. In medicine, fertility refers to the ability to have children, and infertility refers to difficulty in reproducing naturally. In general, infertility or subfertility in humans is defined as not being able to conceive a child after one year of unprotected sex. The antithesis of fertility is infertility, while the antithesis of fecundity is sterility.

<span class="mw-page-title-main">Contraceptive patch</span> Transdermal patch applied to prevent pregnancy

A contraceptive patch, also known as "the patch", is a transdermal patch applied to the skin that releases synthetic oestrogen and progestogen hormones to prevent pregnancy. They have been shown to be as effective as the combined oral contraceptive pill with perfect use, and the patch may be more effective in typical use.

Male contraceptives, also known as male birth control, are methods of preventing pregnancy by interrupting the function of sperm. The main forms of male contraception available today are condoms, vasectomy, and withdrawal, which together represented 20% of global contraceptive use in 2019. New forms of male contraception are in clinical and preclinical stages of research and development, but as of 2024, none have reached regulatory approval for widespread use.

Natural family planning (NFP) comprises the family planning methods approved by the Catholic Church and some Protestant denominations for both achieving and postponing or avoiding pregnancy. In accordance with the Church's teachings regarding sexual behavior, NFP excludes the use of other methods of birth control, which it refers to as "artificial contraception".

<span class="mw-page-title-main">Hormonal contraception</span> Birth control methods that act on the endocrine system

Hormonal contraception refers to birth control methods that act on the endocrine system. Almost all methods are composed of steroid hormones, although in India one selective estrogen receptor modulator is marketed as a contraceptive. The original hormonal method—the combined oral contraceptive pill—was first marketed as a contraceptive in 1960. In the ensuing decades, many other delivery methods have been developed, although the oral and injectable methods are by far the most popular. Hormonal contraception is highly effective: when taken on the prescribed schedule, users of steroid hormone methods experience pregnancy rates of less than 1% per year. Perfect-use pregnancy rates for most hormonal contraceptives are usually around the 0.3% rate or less. Currently available methods can only be used by women; the development of a male hormonal contraceptive is an active research area.

Long-acting reversible contraceptives (LARC) are methods of birth control that provide effective contraception for an extended period without requiring user action. They include hormonal and non-hormonal intrauterine devices (IUDs), and subdermal hormonal contraceptive implants. They are the most effective reversible methods of contraception because their efficacy is not reliant on patient compliance. The failure rates of IUDs and implants is less than 1% per year.

<span class="mw-page-title-main">Birth control</span> Method of preventing human pregnancy

Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent unintended pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using human birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable.

Medroxyprogesterone acetate (MPA), also known as depot medroxyprogesterone acetate (DMPA) in injectable form and sold under the brand name Depo-Provera among others, is a hormonal medication of the progestin type. It is used as a method of birth control and as a part of menopausal hormone therapy. It is also used to treat endometriosis, abnormal uterine bleeding, paraphilia, and certain types of cancer. The medication is available both alone and in combination with an estrogen. It is taken by mouth, used under the tongue, or by injection into a muscle or fat.

Family planning in India is based on efforts largely sponsored by the Indian government. From 1965 to 2009, contraceptive usage has more than tripled and the fertility rate has more than halved, but the national fertility rate in absolute numbers remains high, causing concern for long-term population growth. India adds up to 1,000,000 people to its population every 20 days. Extensive family planning has become a priority in an effort to curb the projected population of two billion by the end of the twenty-first century.

The Responsible Parenthood and Reproductive Health Act of 2012, also known as the Reproductive Health Law or RH Law, and officially designated as Republic Act No. 10354, is a Philippine law that provides universal access to methods of contraception, fertility control, sexual education, and maternal care.

<span class="mw-page-title-main">Family planning in Pakistan</span> Political issue

Even though there is considerable demand for family planning in Pakistan, the adoption of family planning has been hampered by government neglect, lack of services and misconceptions. Demographics play a large role in Pakistan's development and security since the change from military rule to civilian leadership. Challenges to Pakistani's well-being, opportunities for education and employment, and access to health care are escalated due to the country's continuously-growing population. It was estimated in 2005 that Pakistan's population totaled 151 million; a number which grows 1.9 percent annually, equaling a 2.9 million population growth per year. Though Pakistan's fertility rates still exceed those of neighboring South Asian countries with a total fertility rate at 4.1 and contraception use is lower than 35 percent, approximately one-fourth of Pakistani women wish to either delay the birth of their next child or end childbearing altogether.

<span class="mw-page-title-main">Prevalence of birth control</span> Overview article

Globally approximately 45% of those who are married and able to have children use contraception. As of 2007, IUDs were used by about 17% of women of child bearing age in developing countries and 9% in developed countries or more than 180 million women worldwide. Avoiding sex when fertile is used by about 3.6% of women of childbearing age, with usage as high as 20% in areas of South America. As of 2005, 12% of couples are using a male form of contraception with rates of up to 30% in the developed world.

Abortion in Uganda is illegal unless performed by a licensed medical doctor in a situation where the woman's life is deemed to be at risk.

Natural Cycles is a mobile app designed to help women track their fertility. The app predicts the days on which a woman is fertile and may be used for planning pregnancy and contraception. It was developed by scientist Elina Berglund, who founded the company with her husband, Raoul Scherwitzl.
