Determinants of teenage birth rates as an unpooled sample -: Age matters for socioeconomic predictors

Illinois teenage birth rates are estimated both as a pooled sample and also as an unpooled sample (under eighteen years old and eighteen to nineteen years old). The younger teens' are statistically significantly affected by the number of two-parent families in the county. The older teens birth rates have statistically significant coefficients for three additional predictors-county education and income levels and the percent of children living in poverty. Variables that do not have a statistically significant relationship with either group's birth rates are population density and the unemployment rate. The proportion of while population was a statistically significant determinant for the younger teens' birth rate.
