Fertility

Factors generally associated with decreased fertility include wealth, education, female labor participation, urban residence, cost of housing, intelligence, increased female age and (to a lesser degree) increased male age.

There is evidence that, on a population level, intelligence is negatively correlated with fertility rate and positively correlated with survival rate of offspring.

According to the March of Dimes, "At age 25, your risk of having a baby with Down syndrome is 1 in 1,340. At age 30, your risk is 1 in 940. At age 35, your risk is 1 in 353. At age 40, your risk is 1 in 85. At age 45, your risk is 1 in 35."

Males with Down syndrome usually do not father children, while females have lower rates of fertility relative to those who are unaffected.

Fertility awareness refers to a set of practices used to determine the fertile and infertile phases of a woman's menstrual cycle.

These model life tables both established new empirical regularities, and proved invaluable in the development of later techniques for estimating mortality and fertility in populations with inaccurate or incomplete data.

Household decisions analyzed in this journal include consumption, savings, labor supply and other time uses, marriage and divorce, demand for health and other forms of human capital, fertility and investment in children's human capital, households and environmental economics, economics of migration, and economics of religion.

Fertility differs from fecundity, which is defined as the potential for reproduction (influenced by gamete production, fertilization and carrying a pregnancy to term).

Human fertility depends on factors of nutrition, sexual behavior, consanguinity, culture, instinct, endocrinology, timing, economics, way of life, and emotions.

Demographers measure the fertility rate in a variety of ways, which can be broadly broken into "period" measures and "cohort" measures.

Factors generally associated with increased fertility include religiosity, intention to have children, and maternal support.

The "Three-step Analysis" of the fertility process was introduced by Kingsley Davis and Judith Blake in 1956 and makes use of three proximate determinants: The economic analysis of fertility is part of household economics, a field that has grown out of the New Home Economics.

Influential economic analyses of fertility include Becker (1960), Mincer (1963), and Easterlin (1969).

The latter developed the Easterlin hypothesis to account for the Baby Boom.
