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 associated with increased fertility include the intention to have children,^[1] remaining religiosity,^[2] general inter-generational transmission of values,^[1] high status of marriage^[3]^{[non-primary source needed]} and cohabitation,^[4]^{[non-primary source needed]} maternal^[5] and social^[1] support, rural residence,^[1] a small subset of pro-family social programs,^[1] low IQ^[6] such as conscientiousness, and generally increased food production.^[7]

Factors generally associated with decreased fertility include rising income,^[1] value and attitude changes,^[8]^[1] education,^[1]^[9] female labor participation,^[10] population control,^[11] age,^[12] contraception,^[1] partner reluctance to child-bearing,^[1] infertility,^[13] pollution,^[14] and obesity.^[15]
