Fertility factor (demography)

Fertility factors are determinants of the number of children that an individual is likely to have. Fertility factors are mostly positive or negative correlations without certain causations.

Factors generally associated with increased fertility include religiosity, fertile parents, the intention to have children,marriage and cohabitation, maternal and social support, rural residence,familism, social pressure,homophily,patriarchy, single nuclear family households, and governmental monetary family allowances.

Factors generally associated with decreased fertility include income, education,female labor participation,population control,contraception, partner reluctance to having children, intense or unstable relationships, changes in values, higher tax rates, generosity of public pensions,increased female age, and (to a lesser degree) increased male age.

The predictive power of intentions continues to be debated. Research argues that intentions are a good predictor of actual results, which tends to be drawn of ideas from the Theory of Planned Behavior (TPB). According to the Theory of Planned Behavior, intentions stem from three factors, being attitude, subjective norms, and perceived control. Factor one, attitudes regarding children, include the cost of raising them versus perceived benefits. Factor two, subjective norms, is regarding the fact that the influence of others and what is perceived can either increase of decrease the intention to have kids. The third factor, perceived control over behavior, deals with how much control an individual possesses over their own behavior.
