State IQ and Fertility in the United States
Steven M. Shatz, Hofstra University
The relationship between IQ and fertility was examined at the state level within the USA. As predicted, SAT-derived state IQ scores were negatively correlated with three different indicators of state fertility rates. The IQ-fertility relationship remained relatively unchanged when demographic and educational characteristics of the states were controlled for. Limitations and possible causal hypotheses are discussed.
